Mediterranean Sea
Template:Short description Template:About Template:Redirect Template:Redirect Template:Use dmy dates Template:Use British English Template:Infobox body of water
The Mediterranean Sea (Template:IPAc-en Template:Respell) is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean basin and almost completely enclosed by land: on the east by the Levant in West Asia, on the north by Anatolia in West Asia and Southern Europe, on the south by North Africa, and on the west almost by the Morocco–Spain border. The Mediterranean Sea covers an area of about Template:Convert,<ref name="britannica">Template:Britannica URL</ref> representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only Template:Convert wide.
Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago.
The sea was an important route for merchants and travellers of ancient times, facilitating trade and cultural exchange between the peoples of the region. The history of the Mediterranean region is crucial to understanding the origins and development of many modern societies. The Roman Empire maintained nautical hegemony over the sea for centuries and is the only state to have ever controlled all of its coast.
The Mediterranean Sea has an average depth of Template:Convert and the deepest recorded point is Template:Convert in the Calypso Deep in the Ionian Sea. It lies between latitudes 30° and 46° N and longitudes 6° W and 36° E. Its west–east length, from the Strait of Gibraltar to the Gulf of Alexandretta, on the southeastern coast of Turkey, is about Template:Convert. The north–south length varies greatly between different shorelines and whether only straight routes are considered. Also including longitudinal changes, the shortest shipping route between the multinational Gulf of Trieste and the Libyan coastline of the Gulf of Sidra is about Template:Convert. The water temperatures are mild in winter and warm in summer and give name to the Mediterranean climate type due to the majority of precipitation falling in the cooler months. Its southern and eastern coastlines are lined with hot deserts not far inland, but the immediate coastline on all sides of the Mediterranean tends to have strong maritime moderation.
The countries surrounding the Mediterranean and its marginal seas in clockwise order are Spain, France, Monaco, Italy, Slovenia, Croatia, Bosnia and Herzegovina, Montenegro, Albania, Greece, Turkey, Syria, Lebanon, Israel, Palestine (Gaza Strip), Egypt, Libya, Tunisia, Algeria, and Morocco; Cyprus and Malta are island countries in the sea. In addition, Northern Cyprus (de facto state) and two overseas territories of the United Kingdom (Akrotiri and Dhekelia, and Gibraltar) also have coastlines along the Mediterranean Sea. The drainage basin encompasses a large number of other countries, the Nile being the longest river ending in the Mediterranean Sea.<ref>Template:Cite web</ref> The Mediterranean Sea encompasses a vast number of islands, some of them of volcanic origin. The two largest islands, in both area and population, are Sicily and Sardinia.
Names and etymology
[edit]
The Ancient Egyptians called the Mediterranean Wadj-wr/Wadj-Wer/Wadj-Ur. This term (literally "great green") was the name given by the Ancient Egyptians to the semi-solid, semi-aquatic region characterised by papyrus forests to the north of the cultivated Nile delta, and, by extension, the sea beyond.<ref>Template:Cite book</ref>
The Ancient Greeks called the Mediterranean simply Template:Lang (hē thálassa; "the Sea") or sometimes Template:Lang (hē megálē thálassa; "the Great Sea"), Template:Lang (hē hēmetérā thálassa; "Our Sea"), or Template:Lang (hē thálassa hē kath’hēmâs; "the sea around us").
The Romans called it Mare Magnum ("Great Sea") or Mare Internum ("Internal Sea") and, starting with the Roman Empire, Mare Nostrum ("Our Sea"). The term Mare Mediterrāneum appears later: Solinus apparently used this in the 3rd century, but the earliest extant witness to it is in the 6th century,<ref name="Seirinidou2017">Vaso Seirinidou, "The Mediterranean" in Diana Mishkova, Balázs Trencsényi, European Regions and Boundaries: A Conceptual History, series European Conceptual History 3, Template:Isbn, 2017, p. 80</ref> in Isidore of Seville.<ref>Template:Cite book</ref> It means 'in the middle of land, inland' in Latin, a compound of medius ("middle"), terra ("land, earth"), and -āneus ("having the nature of").
The modern Greek name Template:Lang (mesógeios; "inland") is a calque of the Latin name, from Template:Lang (mésos, "in the middle") and Template:Lang (gḗinos, "of the earth"), from Template:Lang (gê, "land, earth"). The original meaning may have been 'the sea in the middle of the earth', rather than 'the sea enclosed by land'.<ref>Template:Cite web</ref><ref>Template:Cite OED</ref>
Ancient Iranians called it the "Roman Sea", and in Classical Persian texts, it was called Daryāy-e Rōm (دریای روم), which may be from Middle Persian form, Zrēh ī Hrōm (𐭦𐭫𐭩𐭤 𐭩 𐭤𐭫𐭥𐭬).<ref>Template:Cite web</ref>
The Carthaginians called it the "Syrian Sea". In ancient Syrian texts, Phoenician epics and in the Hebrew Bible, it was primarily known as the "Great Sea", הים הגדול HaYam HaGadol, (Numbers; Book of Joshua; Ezekiel) or simply as "The Sea" (1 Kings). However, it has also been called the "Hinder Sea" because of its location on the west coast of the region of Syria or the Holy Land (and therefore behind a person facing the east), which is sometimes translated as "Western Sea". Another name was the "Sea of the Philistines", (Book of Exodus), from the people inhabiting a large portion of its shores near the Israelites. In Modern Hebrew, it is called הים התיכון HaYam HaTikhon 'the Middle Sea'.<ref name="melitensia" /> In Classic Persian texts was called Daryāy-e Šām (دریای شام) "The Western Sea" or "Syrian Sea".<ref>Template:Cite web</ref>
In Modern Standard Arabic, it is known as Template:Transliteration (Template:Lang) 'the [White] Middle Sea'. In Islamic and older Arabic literature, it was Baḥr al-Rūm(ī) (Template:Lang or Template:Lang) 'the Sea of the Romans' or 'the Roman Sea'. At first, that name referred only to the eastern Mediterranean, but the term was later extended to the whole Mediterranean. Other Arabic names were Baḥr al-šām(ī) (Template:Lang) ("the Sea of Syria") and Baḥr al-Maghrib (Template:Lang) ("the Sea of the West").<ref name="eoi">"Baḥr al-Rūm" in Encyclopedia of Islam, 2nd ed</ref><ref name="Seirinidou2017"/>
In Turkish, it is the Akdeniz 'the White Sea'; in Ottoman, Template:Lang, which sometimes means only the Aegean Sea.<ref>Diran Kélékian, Dictionnaire Turc-Français, Constantinople, 1911</ref> The origin of the name is not clear, as it is not known in earlier Greek, Byzantine or Islamic sources. It may be to contrast with the Black Sea.<ref name="eoi"/><ref name="melitensia">Template:Cite journal</ref><ref>Özhan Öztürk claims that in Old Turkish ak also means "west" and that Akdeniz hence means "West Sea" and that Karadeniz (Black Sea) means "North Sea". Özhan Öztürk. Template:Cite book</ref> In Persian, the name was translated as Baḥr-i Safīd, which was also used in later Ottoman Turkish.<ref name="eoi"/> Similarly, in 19th century Greek, the name was Template:Lang (áspri thálassa; "white sea").<ref>Template:Cite web</ref><ref>Template:Cite web</ref>
According to Johann Knobloch, in classical antiquity, cultures in the Levant used colours to refer to the cardinal points: black referred to the north (explaining the name Black Sea), yellow or blue to east, red to south (e.g., the Red Sea) and white to west. That would explain the Bulgarian Byalo More, the Turkish Akdeniz, and the Arab nomenclature described above, Template:Abbr "White Sea".<ref>Johann Knoblock.

History
[edit]Ancient civilisations
[edit]
Major ancient civilisations were located around the Mediterranean. The sea provided routes for trade, colonisation, and war, as well as food (from fishing and the gathering of other seafood) for numerous communities throughout the ages.<ref>Template:Cite book</ref> The earliest advanced civilisations in the Mediterranean were the Egyptians and the Minoans, who traded extensively with each other. Other notable civilisations that appeared somewhat later are the Hittites and other Anatolian peoples, the Phoenicians, and Mycenean Greece. Around 1200 BC the eastern Mediterranean was greatly affected by the Bronze Age Collapse, which resulted in the destruction of many cities and trade routes.
The most notable Mediterranean civilisations in classical antiquity were the Greek city states and the Phoenicians, both of which extensively colonised the coastlines of the Mediterranean.
Darius I of Persia, who conquered Ancient Egypt, built a canal linking the Red Sea to the Nile, and thus the Mediterranean. Darius's canal was wide enough for two triremes to pass each other with oars extended and required four days to traverse.<ref>Rappoport, S. (Doctor of Philosophy, Basel). History of Egypt (undated, early 20th century), Volume 12, Part B, Chapter V: "The Waterways of Egypt", pp. 248–257 (online). London: The Grolier Society.</ref>
Following the Punic Wars in the 3rd and 2nd centuries BC, the Roman Republic defeated the Carthaginians to become the preeminent power in the Mediterranean. When Augustus founded the Roman Empire, the Romans referred to the Mediterranean as Mare Nostrum ("Our Sea"). For the next 400 years, the Roman Empire completely controlled the Mediterranean Sea and virtually all its coastal regions from Gibraltar to the Levant, being the only state in history to ever do so, being given the nickname "Roman Lake".
Middle Ages and empires
[edit]The Western Roman Empire collapsed around 476 AD. The east was again dominant as Roman power lived on in the Byzantine Empire formed in the 4th century from the eastern half of the Roman Empire. Though the Eastern Roman Empire would continue to hold almost all of the Mediterranean, another power arose in the 7th century, and with it the religion of Islam, which soon swept across from the east; at its greatest extent, the Arabs, under the Umayyads, controlled most of the Mediterranean region and left a lasting footprint on its eastern and southern shores.
A variety of foodstuffs, spices and crops were introduced to the western Mediterranean's Spain and Sicily during Arab rule, via the commercial networks of the Islamic world. These include sugarcane,<ref name="spanish-food.org">Template:Cite web</ref> rice,<ref>Template:Cite journal</ref> cotton, alfalfa, oranges,<ref>Template:Cite web</ref> lemons,<ref>Template:Cite web</ref> apricots,<ref>Template:Cite web</ref> spinach,<ref>Template:Cite web</ref> eggplants,<ref>Template:Cite journal</ref> carrots,<ref>Template:Cite web</ref> saffron<ref>Template:Cite web</ref> and bananas.<ref>Template:Cite web</ref> The Arabs also continued extensive cultivation and production of olive oil (the Spanish words for 'oil' and 'olive'—aceite and aceituna, respectively—are derived from the Arabic al-zait, meaning 'olive juice'),<ref>Template:Cite web</ref> and pomegranates (the heraldic symbol of Granada) from classical Greco-Roman times.
The Arab invasions disrupted the trade relations between Western and Eastern Europe while disrupting trade routes with Eastern Asian Empires. This, however, had the indirect effect of promoting trade across the Caspian Sea. The export of grains from Egypt was re-routed towards the Eastern world. Products from East Asian empires, like silk and spices, were carried from Egypt to ports like Venice and Constantinople by sailors and Jewish merchants. The Viking raids further disrupted the trade in western Europe and brought it to a halt. However, the Norsemen developed the trade from Norway to the White Sea, while also trading in luxury goods from Spain and the Mediterranean. The Byzantines in the mid-8th century retook control of the area around the north-eastern part of the Mediterranean. Venetian ships from the 9th century armed themselves to counter the harassment by Arabs while concentrating trade of Asian goods in Venice.<ref>Template:Cite book</ref>
The Fatimids maintained trade relations with the Italian city-states like Amalfi and Genoa before the Crusades, according to the Cairo Geniza documents. A document dated 996 mentions Amalfian merchants living in Cairo. Another letter states that the Genoese had traded with Alexandria. The caliph al-Mustansir had allowed Amalfian merchants to reside in Jerusalem about 1060 in place of the Latin hospice.<ref>Template:Cite book</ref>
The Crusades led to the flourishing of trade between Europe and the outremer region.<ref>Template:Cite book</ref> Genoa, Venice and Pisa created colonies in regions controlled by the Crusaders and came to control the trade with the Orient. These colonies also allowed them to trade with the Eastern world. Though the fall of the Crusader states and attempts at banning of trade relations with Muslim states by the Popes temporarily disrupted the trade with the Orient, it however continued.<ref>Template:Cite book</ref>
Europe started to revive, however, as more organised and centralised states began to form in the later Middle Ages after the Renaissance of the 12th century.
Ottoman power based in Anatolia continued to grow, and in 1453 extinguished the Byzantine Empire with the Conquest of Constantinople. Ottomans gained control of much of the eastern part sea in the 16th century and also maintained naval bases in southern France (1543–1544), Algeria and Tunisia. Barbarossa, the Ottoman captain is a symbol of this domination with the victory of the Battle of Preveza (1538). The Battle of Djerba (1560) marked the apex of Ottoman naval domination in the eastern Mediterranean. As the naval prowess of the European powers increased, they confronted Ottoman expansion in the region when the Battle of Lepanto (1571) checked the power of the Ottoman Navy. This was the last naval battle to be fought primarily between galleys.
The Barbary pirates of Northwest Africa preyed on Christian shipping and coastlines in the Western Mediterranean Sea.<ref>Template:Cite book</ref> According to Robert Davis, from the 16th to 19th centuries, pirates captured 1 million to 1.25 million Europeans as slaves.<ref>Template:Cite web</ref>
The development of oceanic shipping began to affect the entire Mediterranean. Once, most of the trade between Western Europe and the East was passing through the region, but after the 1490s the development of a sea route to the Indian Ocean allowed the importation of Asian spices and other goods through the Atlantic ports of western Europe.<ref>C.I.

The sea remained strategically important. British mastery of Gibraltar ensured their influence in Africa and Southwest Asia. Especially after the naval battles of Abukir (1799, Battle of the Nile) and Trafalgar (1805), the British had for a long time strengthened their dominance in the Mediterranean.<ref>See: Brian Lavery "Nelson's Navy: The Ships, Men, and Organization, 1793–1815" (2013).</ref> Wars included Naval warfare in the Mediterranean during World War I and Mediterranean theatre of World War II.
With the opening of the lockless Suez Canal in 1869, the flow of trade between Europe and Asia changed fundamentally. The fastest route now led through the Mediterranean towards East Africa and Asia. This led to a preference for the Mediterranean countries and their ports like Trieste with direct connections to Central and Eastern Europe experienced a rapid economic rise. In the 20th century, the 1st and 2nd World Wars as well as the Suez Crisis and the Cold War led to a shift of trade routes to the European northern ports, which changed again towards the southern ports through European integration, the activation of the Silk Road and free world trade.<ref>Mary Pelletier "A brief history of the Suez Canal" In: Apollo 3 July 2018; Harry de Wilt: Is One Belt, One Road a China crisis for North Sea main ports? in World Cargo News, 17.

21st century and migrations
[edit]Template:FurtherTemplate:CSS image crop In 2013, the Maltese president described the Mediterranean Sea as a "cemetery" due to the large number of migrants who drowned there after their boats capsized.<ref>Template:Cite web</ref> European Parliament president Martin Schulz said in 2014 that Europe's migration policy "turned the Mediterranean into a graveyard", referring to the number of drowned refugees in the region as a direct result of the policies.<ref>Template:Cite web</ref> An Azerbaijani official described the sea as "a burial ground ... where people die".<ref>Template:Cite web</ref>
Following the 2013 Lampedusa migrant shipwreck, the Italian government decided to strengthen the national system for the patrolling of the Mediterranean Sea by authorising "Operation Mare Nostrum", a military and humanitarian mission in order to rescue the migrants and arrest the traffickers of immigrants. In 2015, more than one million migrants crossed the Mediterranean Sea into Europe.<ref>Template:Cite web</ref>
Italy was particularly affected by the European migrant crisis. Since 2013, over 700,000 migrants have landed in Italy,<ref>Template:Cite news</ref> mainly sub-Saharan Africans.<ref>Template:Cite news</ref>
Geography
[edit]Template:Multiple imageTemplate:See also The Mediterranean Sea connects:
- to the Atlantic Ocean by the Strait of Gibraltar (known in Homer's writings as the "Pillars of Hercules") in the west
- to the Sea of Marmara and the Black Sea, by the Straits of the Dardanelles and the Bosporus respectively, in the east
The Template:Convert long artificial Suez Canal in the southeast connects the Mediterranean Sea to the Red Sea without ship lock, because the water level is essentially the same.<ref name="melitensia"/><ref>Harald Krachler "Alois Negrelli, der Suezkanalplaner" In: Wiener Zeitung 18 January 1999.</ref>
The westernmost point of the Mediterranean is located at the transition from the Alborán Sea to the Strait of Gibraltar, the easternmost point is on the coast of the Gulf of Iskenderun in southeastern Turkey. The northernmost point of the Mediterranean is on the coast of the Gulf of Trieste near Monfalcone in northern Italy while the southernmost point is on the coast of the Gulf of Sidra near the Libyan town of El Agheila.
Large islands in the Mediterranean include:
- Cyprus, Crete, Euboea, Rhodes, Lesbos, Chios, Kefalonia, Corfu, Limnos, Samos, Naxos, and Andros in the Eastern Mediterranean
- Sicily, Cres, Krk, Brač, Hvar, Pag, Korčula, and Malta in the central Mediterranean
- Sardinia, Corsica, and the Balearic Islands: Ibiza, Mallorca, and Menorca in the Western Mediterranean
The Alpine arc, which also has a great meteorological impact on the Mediterranean area, touches the Mediterranean in the west in the area around Nice.
The typical Mediterranean climate has hot, dry summers and mild, rainy winters. Crops of the region include olives, grapes, oranges, tangerines, carobs and cork.

Extent
[edit]
The International Hydrographic Organization defines the limits of the Mediterranean Sea as follows:<ref name="IHO">Template:Cite web</ref> Stretching from the Strait of Gibraltar in the west to the entrances to the Dardanelles and the Suez Canal in the east, the Mediterranean Sea is bounded by the coasts of Europe, Africa, and Asia and is divided into two deep basins:
- Western Basin:
- On the west: A line joining the extremities of Cape Trafalgar (Spain) and Cape Spartel (Africa)
- On the northeast: The west coast of Italy. In the Strait of Messina, a line joining the north extreme of Cape Paci (15°42′E) with Cape Peloro, the east extreme of the Island of Sicily. The north coast of Sicily
- On the east: A line joining Cape Lilibeo the western point of Sicily (Template:Coord), through the Adventure Bank to Cape Bon (Tunisia)
- Eastern Basin:
- On the west: The northeastern and eastern limits of the Western Basin
- On the northeast: A line joining Kum Kale (26°11′E) and Cape Helles, the western entrance to the Dardanelles
- On the southeast: The entrance to the Suez Canal
- On the east: The coasts of Lebanon, Syria, Israel, and Palestine (through the Gaza Strip)
Hydrography
[edit]
The drainage basin of the Mediterranean Sea is particularly heterogeneous and extends much further than the Mediterranean region.<ref>Template:Cite book</ref> Its size has been estimated between Template:Convert,Template:NoteTag depending on whether non-active parts (deserts) are included or not.<ref>Template:Cite book</ref><ref name="Margat 2004 p4">Template:Cite book</ref><ref>Template:Cite journal</ref> The longest river ending in the Mediterranean Sea is the Nile, which takes its sources in equatorial Africa. The basin of the Nile constitutes about two-thirds of the Mediterranean drainage basin<ref name="Margat 2004 p4" /> and encompasses areas as high as the Ruwenzori Mountains.<ref>Template:Cite book</ref> Among other important rivers in Africa, are the Moulouya and the Chelif, both on the north side of the Atlas Mountains. In Asia, are the Ceyhan and Seyhan, both on the south side of the Taurus Mountains.<ref name="UNEP">Template:Cite web</ref> In Europe, the largest basins are those of the Rhône, Ebro, Po, and Maritsa.<ref name="UNECE">Template:Cite book</ref> The basin of the Rhône is the largest and extends up as far north as the Jura Mountains, encompassing areas even on the north side of the Alps.<ref>Template:Cite book</ref> The basins of the Ebro, Po, and Maritsa, are respectively south of the Pyrenees, Alps, and Balkan Mountains, which are the major ranges bordering Southern Europe.
Total annual precipitation is significantly higher on the European part of the Mediterranean basin, especially near the Alps (the 'water tower of Europe') and other high mountain ranges. As a consequence, the river discharges of the Rhône and Po are similar to that of the Nile, despite the latter having a much larger basin.<ref name="UNEP" /> These are the only three rivers with an average discharge of over Template:Convert.<ref name="Margat 2004 p4"/> Among large natural fresh bodies of water are Lake Victoria (Nile basin), Lake Geneva (Rhône), and the Italian Lakes (Po). While the Mediterranean watershed is bordered by other river basins in Europe, it is essentially bordered by endorheic basins or deserts elsewhere.
The following countries are in the Mediterranean drainage basin while not having a coastline on the Mediterranean Sea:
- In Europe, through various rivers:<ref name="UNECE"/> Andorra,Template:NoteTag Bulgaria,Template:NoteTag Kosovo,Template:Notetag North Macedonia,Template:NoteTag San Marino,Template:NoteTag Serbia,Template:NoteTag and Switzerland.Template:NoteTag
- In Africa, through the Nile:<ref>Template:Cite web</ref> Congo, Burundi, Eritrea, Ethiopia, Kenya, Rwanda, South Sudan, Sudan, Tanzania and Uganda.

Climate
[edit]Much of the Mediterranean coast enjoys a hot-summer Mediterranean climate. However, most of its southeastern coast has a hot desert climate, and much of Spain's eastern (Mediterranean) coast has a cold semi-arid climate, while most of Italy's northern (Adriatic) coast has a humid subtropical climate. Although they are rare, tropical cyclones occasionally form in the Mediterranean Sea, typically in September–November.

[edit]The Mediterranean Sea has numerous underwater geological features formed by the subduction of the African Plate beneath the Eurasian Plate.<ref>Template:Cite journal</ref><ref>Template:Cite journal</ref> The sea is divided naturally into western and eastern regions by the Malta Escarpment that runs from the island of Sicily to the African coast.<ref name=":0">Template:Cite encyclopedia</ref><ref name=":1">Template:Cite book</ref><ref name=":2">Template:Cite journal</ref><ref>Template:Cite journal</ref>
The western Mediterranean region may be separated into three main underwater basins:<ref>Template:Cite journal</ref>
- the Alboran Basin lies between the Moroccan and Spanish coasts, east of Gibraltar, west of Sardinia and Corsica, which acts as a gateway between the Atlantic Ocean and the Mediterranean Sea and is a biodiversity hotspot.<ref>Template:Cite web</ref>
- the Algerian Basin stretches from the Algerian coast to the French coast, and includes depths of up to Template:Convert.<ref>Template:Cite journal</ref> There has been significant hydrocarbon exploration, particularly off the coasts of Algeria, Libya, and Tunisia;<ref>Template:Cite report</ref> The Campi Flegrei del Mar di Sicilia is a field of submarine volcanoes located about Template:Convert southwest of Sicily very close to sea level and which temporarily emerge above sea level during significant eruptions. These include Ferdinandea, also known as Graham Island, and Empedocles;<ref>Template:Cite web</ref>
- the Tyrrhenian Basin, also referred to as the Tyrrhenian Sea, between Italy and the islands of Sardinia and Corsica.<ref name=":0" /><ref name=":1" /> The basin includes Marsili, a large undersea volcano in the Tyrrhenian Sea, about Template:Convert south of Naples, and the Palinuro Seamount, one of the largest in the Tyrrhenian Sea and lies about Template:Convert northeast from Marsili. Marsili is one of the largest volcanoes in Europe, with a length of Template:Convert and a width of 30 kilometres, larger than Mount Etna and part of the Aeolian Islands volcanic arc.<ref>Template:Cite web</ref>
The eastern Mediterranean region may also be subdivided into the following underwater basins:
- the Ionian Basin, which is a deep and narrow oceanic basin, stretches south of Italy, Albania, and Greece and contains the Calypso Deep, also known as the Oinousses or Vavilov Deep, featuring the deepest point in the Mediterranean Sea, located in the Hellenic Trench, Template:Convert southwest of Pylos, Greece, with a maximum depth of approximately Template:Convert;<ref name=":0" />
- the Levantine Basin to the south of Anatolia separated from the Ionian Basin by the Mediterranean Ridge. The Template:Convert-long submarine ridge running from Calabria along the south of Crete, to the southwest corner of Turkey is a Template:Convert-wide curved feature, which is also known for its mud volcanoes and dome-like structures and has been the subject of studies on the Messinian salinity crisis.<ref name=":2" /> The Eratosthenes Seamount, a carbonate seamount is found in the Levantine basin about Template:Convert south of western Cyprus.
- the island of Crete delineates the Levantine Basin from the Aegean Sea, which is that portion of the Mediterranean Sea north of Crete and is bordered on the east by the coast of Turkey and on the west and north by the coast of Greece. Numerous Greek islands and seamounts are located in the Aegean Sea;<ref name=":0" /><ref>Template:Cite book</ref> and
- the Adriatic Sea, which is northwest of the eastern Mediterranean Sea's main body, is bordered to the east by Slovenia, Croatia, Bosnia and Herzegovina, Montenegro, and Albania, and to the west and north by Italy.<ref name=":0" /><ref name=":1" />
Until the 1960s, the Mediterranean was believed to be the primary remaining portion of the earlier (200 million years old) Mesozoic Tethys Ocean, which once encircled the Eastern Hemisphere. However, since the late 20th century, research using the theory of seafloor spreading has indicated that most of the current Mediterranean seafloor is not a portion of the Tethys sea floor.<ref name=":0" /> Some researchers consider the Ionian Basin, to the east of the Malta Escarpment, to be the remnant of the Tethys Ocean.<ref>Template:Cite journal</ref> Over the course of the last 44 million years, the continental plates of Africa and Eurasia have converged and receded, resulting in the current tectonically active basin and its surrounding mountain chains. According to the interpretation of geologic data, there are currently several major places where Africa and Eurasia collide, causing land submergence, mountain building, and volcanism.<ref name=":0" />
Sediment cores drilled in 1970 and 1975 led to theories that about 6 million years ago, the Mediterranean was around Template:Convert below the current sea level and included arid deserts blanketed with evaporite salts. It was thought that Gibraltar's high ridges prevented Atlantic waters from entering until roughly 5.5 million years ago, when they broke through and flooded the Mediterranean. According to more recent seismic and microfossil research, the seafloor was never entirely dry. Rather approximately 5 million years ago, the seafloor was made up of many basins with varying topography and sizes, spanning in depth from Template:Convert. Salts were likely accumulated on the bottom of highly salinised waters of widely differing depths. The uncertainty of the timing and nature of sea-bottom salt formation and evidence from later seismic research and core samples has been the subject of intense scientific debate.<ref name=":0" />
Malta Escarpment
[edit]The Malta Escarpment is a Template:Convert undersea limestone escarpment that stretches south from Sicily's eastern coast to the Maltese islands' eastern coast and beyond, primarily formed due to tectonic activities.<ref name=":0" /> There are more than 500 undersea canyons along the cliffs, which can reach heights of Template:Convert in some locations. Rich biological communities may be found in the canyons, which also serve as channels for contaminants and nutrients due to underwater currents. These deep valleys are special due to the fact that they were not carved out by surface rivers. Underwater landslides are among the natural hazards found on the Malta Escarpment. The University of Malta, UK National Oceanography Centre, New Zealand National Institute of Water and Atmospheric Research, University College Dublin and Italy’s Istituto Nazionale di Oceanografia e Geofisica collaborated on a recent study financed by the European Union that focused on the Escarpment.<ref name=":1" /><ref>Template:Cite web</ref>
Oceanography
[edit]
Being nearly landlocked affects conditions in the Mediterranean Sea: for instance, tides are very limited as a result of the narrow connection with the Atlantic Ocean. The Mediterranean is characterised and immediately recognised by its deep blue colour.
Evaporation greatly exceeds precipitation and river runoff in the Mediterranean, a fact that is central to the water circulation within the basin.<ref>Template:Cite book</ref> Evaporation is especially high in its eastern half, causing the water level to decrease and salinity to increase eastward.Template:Sfn The average salinity in the basin is 38 PSU at Template:Convert depth.<ref name=tempandsal>Template:Cite journal</ref> The temperature of the water in the deepest part of the Mediterranean Sea is Template:Convert.<ref name=tempandsal/>
The net water influx from the Atlantic Ocean is ca. Template:Convert or Template:Convert.<ref>Template:Cite journal</ref> Without this Atlantic water, the sea level of the Mediterranean Sea would fall at a rate of about Template:Convert per year.<ref>Template:Cite book</ref>
In oceanography, it is sometimes called the Eurafrican Mediterranean Sea, the European Mediterranean Sea or the African Mediterranean Sea to distinguish it from mediterranean seas elsewhere.<ref>Template:Cite report</ref>Template:Who else
General circulation
[edit]Water circulation in the Mediterranean can be attributed to the surface waters entering from the Atlantic through the Strait of Gibraltar (and also low salinity water entering the Mediterranean from the Black Sea through the Bosphorus). The cool and relatively low-salinity Atlantic water circulates eastwards along the North African coasts. A part of the surface water does not pass the Strait of Sicily, but deviates towards Corsica before exiting the Mediterranean. The surface waters entering the eastern Mediterranean Basin circulate along the Libyan and Israeli coasts. Upon reaching the Levantine Sea, the surface waters having warmed and increased its salinity from its initial Atlantic state, is now denser and sinks to form the Levantine Intermediate Waters (LIW). Most of the water found anywhere between Template:Convert deep in the Mediterranean originates from the LIW.<ref>Template:Cite book</ref> LIW are formed along the coasts of Turkey and circulate westwards along the Greek and south Italian coasts. LIW are the only waters passing the Sicily Strait westwards. After the Strait of Sicily, the LIW waters circulate along the Italian, French and Spanish coasts before exiting the Mediterranean through the depths of the Strait of Gibraltar. Deep water in the Mediterranean originates from three main areas: the Adriatic Sea, from which most of the deep water in the eastern Mediterranean originates, the Aegean Sea, and the Gulf of Lion. Deep water formation in the Mediterranean is triggered by strong winter convection fueled by intense cold winds like the Bora. When new deep water is formed, the older waters mix with the overlaying intermediate waters and eventually exit the Mediterranean. The residence time of water in the Mediterranean is approximately 100 years, making the Mediterranean especially sensitive to climate change.<ref>Template:Cite journal</ref>
Other events affecting water circulation
[edit]Being a semi-enclosed basin, the Mediterranean experiences transitory events that can affect the water circulation on short time scales. In the mid-1990s, the Aegean Sea became the main area for deep water formation in the eastern Mediterranean after particularly cold winter conditions. This transitory switch in the origin of deep waters in the eastern Mediterranean was termed Eastern Mediterranean Transient (EMT) and had major consequences on water circulation of the Mediterranean.<ref>Template:Cite journal</ref><ref>Template:Cite journal</ref><ref>Template:Cite journal</ref>
Another example of a transient event affecting the Mediterranean circulation is the periodic inversion of the North Ionian Gyre, which is an anticyclonic ocean gyre observed in the northern part of the Ionian Sea, off the Greek coast. The transition from anticyclonic to cyclonic rotation of this gyre changes the origin of the waters fueling it; when the circulation is anticyclonic (most common), the waters of the gyre originate from the Adriatic Sea. When the circulation is cyclonic, the waters originate from the Levantine Sea. These waters have different physical and chemical characteristics, and the periodic inversion of the North Ionian Gyre (called Bimodal Oscillating System or BiOS) changes the Mediterranean circulation and biogeochemistry around the Adriatic and Levantine regions.<ref>Template:Cite journal</ref>
Climate change
[edit]Because of the short residence time of its waters, the Mediterranean Sea is considered a hot-spot for climate change records,<ref name="Giorgi, F. 2006">Template:Cite journal</ref> registering indeed marked increases in temperature across the entire water column since the 1950s.<ref>Template:Cite journal</ref><ref>Template:Cite journal</ref> According to climate projections, the decrease in precipitation over the region will lead to more evaporation, ultimately increasing marine salinity.<ref>Template:Cite journal</ref> As a result of both temperature and salinity increases, the Mediterranean Sea is likely to become more stratified by the end of the 21st century, with notable consequences on water circulation and biogeochemistry. The stratification and warming have already led the eastern Mediterranean to become a net source of CO2 to the atmosphere<ref>Template:Cite journal</ref><ref>Template:Cite journal</ref> notably during summer.
Human-induced climate change appears to play a growing role in the development of marine heatwaves that have become a prominent subject of research in recent years, particularly in the Mediterranean where a number of areas in both western and eastern sub-basins now experience peaks of temperatures, along with more frequent, more intense, more prolonged warming events than ever seen on record. These events, mainly driven by a combination of oceanic and atmospheric factors, are often triggered by high pressure systems that will reduce cloud cover and increase solar absorption by the sea surface. Their impacts on marine ecosystems, such as mass mortality in benthic communities, coral bleaching events, disruptions in fishery catches and shifts in species distributions, can be devastating.<ref>Marine heatwaves in the Mediterranean Sea and beyond - an overview. 2024. pp. 5–24 in CIESM Monograph 51 (F. Briand, Ed.) ISSN 1726-5886 [1]</ref> Extreme warming can lead to biodiversity loss<ref>Template:Cite journal</ref> and presents an existential threat to some habitats<ref>Template:Cite journal</ref> while making conditions more hospitable to invasive tropical species.<ref>Template:Cite journal</ref>
Biogeochemistry
[edit]
In spite of its great biodiversity, concentrations of chlorophyll and nutrients in the Mediterranean Sea are very low, making it one of the most oligotrophic ocean regions in the world. The Mediterranean Sea is commonly referred to as an LNLC (Low-Nutrient, Low-Chlorophyll) area. The Mediterranean Sea fits the definition of a desert in which its nutrient contents are low, making it difficult for plants and animals to develop.
There are steep gradients in nutrient concentrations, chlorophyll concentrations and primary productivity in the Mediterranean. Nutrient concentrations in the western part of the basin are about double the concentrations in the eastern basin. The Alboran Sea, close to the Strait of Gibraltar, has a daily primary productivity of about 0.25 g C (grams of carbon) m−2 day−1 whereas the eastern basin has an average daily productivity of 0.16 g C m−2 day−1.<ref name="Uitz Stramski Gentili DOrtenzio 2012 p. ">Template:Cite journal</ref> For this reason, the eastern part of the Mediterranean Sea is termed "ultraoligotrophic". The productive areas of the Mediterranean Sea are few and small. High (i.e. more than 0.5 grams of Chlorophyll a per cubic meter) productivity occurs in coastal areas, close to the river mouths which are the primary suppliers of dissolved nutrients. The Gulf of Lion has a relatively high productivity because it is an area of high vertical mixing, bringing nutrients to the surface waters that can be used by phytoplankton to produce Chlorophyll a.<ref name="Bosc, E. 2004">Template:Cite journal</ref>
Primary productivity in the Mediterranean is also marked by an intense seasonal variability. In winter, the strong winds and precipitation over the basin generate vertical mixing, bringing nutrients from the deep waters to the surface, where phytoplankton can convert it into biomass.<ref>Template:Cite journal</ref> However, in winter, light may be the limiting factor for primary productivity. Between March and April, spring offers the ideal trade-off between light intensity and nutrient concentrations in surface for a spring bloom to occur. In summer, high atmospheric temperatures lead to the warming of the surface waters. The resulting density difference virtually isolates the surface waters from the rest of the water column and nutrient exchanges are limited. As a consequence, primary productivity is very low between June and October.<ref>Template:Cite journal</ref><ref name="Bosc, E. 2004"/>
Oceanographic expeditions uncovered a characteristic feature of the Mediterranean Sea biogeochemistry: most of the chlorophyll production does not occur on the surface, but in sub-surface waters between 80 and 200 meters deep.<ref>Template:Cite journal</ref> Another key characteristic of the Mediterranean is its high nitrogen-to-phosphorus ratio (N:P). Redfield demonstrated that most of the world's oceans have an average N:P ratio around 16. However, the Mediterranean Sea has an average N:P between 24 and 29, which translates a widespread phosphorus limitation.Template:Clarify<ref>Template:Cite journal</ref><ref>Template:Cite journal</ref><ref>Template:Cite journal</ref><ref>Template:Cite journal.</ref>
Because of its low productivity, plankton assemblages in the Mediterranean Sea are dominated by small organisms such as picophytoplankton and bacteria.<ref>Template:Cite journal</ref><ref name="Uitz Stramski Gentili DOrtenzio 2012 p. "/>
Geology
[edit]
The geologic history of the Mediterranean Sea is complex. Underlain by oceanic crust, the sea basin was once thought to be a tectonic remnant of the ancient Tethys Ocean; it is now known to be a structurally younger basin, called the Neotethys, which was first formed by the convergence of the African Plate and Eurasian Plate during the Late Triassic and Early Jurassic. Because it is a near-landlocked body of water in a normally dry climate, the Mediterranean is subject to intensive evaporation and the precipitation of evaporites. The Messinian salinity crisis started about six million years ago (mya) when the Mediterranean became landlocked, and then essentially dried up. There are salt deposits accumulated on the bottom of the basin of more than a million cubic kilometres—in some places more than three kilometres thick.<ref>Template:Cite journal</ref><ref>Template:Cite journal</ref>
Scientists estimate that the sea was last filled about 5.3 million years ago (mya) in less than two years by the Zanclean flood. Water poured in from the Atlantic Ocean through a newly breached gateway now called the Strait of Gibraltar at an estimated rate of about three orders of magnitude (one thousand times) larger than the current flow of the Amazon River.<ref name="GCetal2009">Template:Cite journal</ref>
The Mediterranean Sea has an average depth of Template:Convert and the deepest recorded point is Template:Convert in the Calypso Deep in the Ionian Sea. The coastline extends for Template:Convert. A shallow submarine ridge (the Strait of Sicily) between the island of Sicily and the coast of Tunisia divides the sea in two main subregions: the Western Mediterranean, with an area of about Template:Convert; and the Eastern Mediterranean, of about Template:Convert. Coastal areas have submarine karst springs or Template:Langs, which discharge pressurised groundwater into the water from below the surface; the discharge water is usually fresh, and sometimes may be thermal.<ref name="LaMoreaux2001">Template:Cite book</ref><ref>Template:Cite journal Template:In lang</ref>
Tectonics and paleoenvironmental analysis
[edit]Template:Unreferenced section The Mediterranean basin and sea system were established by the ancient African-Arabian continent colliding with the Eurasian continent. As Africa-Arabia drifted northward, it closed over the ancient Tethys Ocean which had earlier separated the two supercontinents Laurasia and Gondwana. At about that time in the middle Jurassic period (roughly 170 million years ago Template:Dubious) a much smaller sea basin, dubbed the Neotethys, was formed shortly before the Tethys Ocean closed at its western (Arabian) end. The broad line of collisions pushed up a very long system of mountains from the Pyrenees in Spain to the Zagros Mountains in Iran in an episode of mountain-building tectonics known as the Alpine orogeny. The Neotethys grew larger during the episodes of collisions (and associated foldings and subductions) that occurred during the Oligocene and Miocene epochs (34 to 5.33 mya); see animation: Africa-Arabia colliding with Eurasia. Accordingly, the Mediterranean basin consists of several stretched tectonic plates in subduction which are the foundation of the eastern part of the Mediterranean Sea. Various zones of subduction contain the highest oceanic ridges, east of the Ionian Sea and south of the Aegean. The Central Indian Ridge runs east of the Mediterranean Sea south-east across the in-betweenTemplate:Clarify of Africa and the Arabian Peninsula into the Indian Ocean.
Messinian salinity crisis
[edit]
During Mesozoic and Cenozoic times, as the northwest corner of Africa converged on Iberia, it lifted the Betic-Rif mountain belts across southern Iberia and northwest Africa. There the development of the intramontane Betic and Rif basins created two roughly parallel marine gateways between the Atlantic Ocean and the Mediterranean Sea. Dubbed the Betic and Rifian corridors, they gradually closed during the middle and late Miocene: perhaps several times.<ref>Template:Cite journal</ref> In the late Miocene the closure of the Betic Corridor triggered the so-called "Messinian salinity crisis" (MSC), characterised by the deposition of a thick evaporitic sequence – with salt deposits up to 2 km thick in the Levantine sea – and by a massive drop in water level in much of the Basin. This event was for long the subject of acute scientific controversy, now much appeased,<ref>Briand, F. (ed.) (2008). The Messinian Salinity Crisis Mega-Deposits to Microbiology – A consensus report. CIESM Publishers, Paris, Monaco. 168 p.[2]</ref> regarding its sequence, geographic range, processes leading to evaporite facies and salt deposits. The start of the MSC was recently estimated astronomically at 5.96 mya, and it persisted for some 630,000 years until about 5.3 mya;<ref>Template:Cite journalTemplate:Dead link</ref> see Animation: Messinian salinity crisis, at right.
After the initial drawdownTemplate:Clarify and re-flooding, there followed more episodes—the total number is debated—of sea drawdowns and re-floodings for the duration of the MSC. It ended when the Atlantic Ocean last re-flooded the basin—creating the Strait of Gibraltar and causing the Zanclean flood—at the end of the Miocene (5.33 mya). Some research has suggested that a desiccation-flooding-desiccation cycle may have repeated several times, which could explain several events of large amounts of salt deposition.<ref>Template:Cite journal</ref><ref>Template:Cite journal</ref> Recent studies, however, show that repeated desiccation and re-flooding is unlikely from a geodynamic point of view.<ref>Template:Cite journal</ref><ref name=GCV>Template:Cite journal</ref>
Desiccation and exchanges of flora and fauna
[edit]Template:See also The present-day Atlantic gateway, the Strait of Gibraltar, originated in the early Pliocene via the Zanclean Flood. As mentioned, there were two earlier gateways: the Betic Corridor across southern Spain and the Rifian Corridor across northern Morocco. The Betic closed about 6 mya, causing the Messinian salinity crisis (MSC); the Rifian or possibly both gateways closed during the earlier Tortonian times, causing a "Tortonian salinity crisis" (from 11.6 to 7.2 mya), long before the MSC and lasting much longer. Both "crises" resulted in broad connections between the mainlands of Africa and Europe, which allowed migrations of flora and fauna—especially large mammals including primates—between the two continents. The Vallesian crisis indicates a typical extinction and replacement of mammal species in Europe during Tortonian times following climatic upheaval and overland migrations of new species:<ref>Template:Cite book (Abstract)</ref> see Animation: Messinian salinity crisis (and mammal migrations), at right.
The almost complete enclosure of the Mediterranean basin has enabled the oceanic gateways to dominate seawater circulation and the environmental evolution of the sea and basin. Circulation patterns are also affected by several other factors—including climate, bathymetry, and water chemistry and temperature—which are interactive and can induce precipitation of evaporites. Deposits of evaporites accumulated earlier in the nearby Carpathian foredeep during the Middle Miocene, and the adjacent Red Sea Basin (during the Late Miocene), and in the whole Mediterranean basin (during the MSC and the Messinian age). Many diatomites are found underneath the evaporite deposits, suggesting a connection between theirTemplate:Clarify formations.
Today, evaporation of surface seawater (output) is more than the supply (input) of fresh water by precipitation and coastal drainage systems, causing the salinity of the Mediterranean to be much higher than that of the Atlantic—so much so that the saltier Mediterranean waters sink below the waters incoming from the Atlantic, causing a two-layer flow across the Strait of Gibraltar: that is, an outflow submarine current of warm saline Mediterranean water, counterbalanced by an inflow surface current of less saline cold oceanic water from the Atlantic. In the 1920s, Herman Sörgel proposed the building of a hydroelectric dam (the Atlantropa project) across the Straits, using the inflow current to provide a large amount of hydroelectric energy. The underlying energy grid was also intended to support a political union between Europe and, at least, the Maghreb part of Africa (compare Eurafrika for the later impact and Desertec for a later project with some parallels in the planned grid).<ref>Politische Geographien Europas: Annäherungen an ein umstrittenes Konstrukt, Anke Strüver, LIT Verlag Münster, 2005, p. 43</ref>
Shift to a "Mediterranean climate"
[edit]The end of the Miocene also marked a change in the climate of the Mediterranean basin. Fossil evidence from that period reveals that the larger basin had a humid subtropical climate with rainfall in the summer supporting laurel forests. The shift to a "Mediterranean climate" occurred largely within the last three million years (the late Pliocene epoch) as summer rainfall decreased. The subtropical laurel forests retreated; and even as they persisted on the islands of Macaronesia off the Atlantic coast of Iberia and North Africa, the present Mediterranean vegetation evolved, dominated by coniferous trees and sclerophyllous trees and shrubs with small, hard, waxy leaves that prevent moisture loss in the dry summers. Much of these forests and shrublands have been altered beyond recognition by thousands of years of human habitation. There are now very few relatively intact natural areas in what was once a heavily wooded region.
Paleoclimate
[edit]Because of its latitude and its landlocked position, the Mediterranean is especially sensitive to astronomically induced climatic variations, which are well documented in its sedimentary record. Since the Mediterranean is subject to the deposition of eolian dust from the Sahara during dry periods, whereas riverine detrital input prevails during wet ones, the Mediterranean marine sapropel-bearing sequences provide high-resolution climatic information. These data have been employed in reconstructing astronomically calibrated time scales for the last 9 Ma of the Earth's history, helping to constrain the time of past geomagnetic reversals.<ref>Template:Cite journal</ref> Furthermore, the exceptional accuracy of these paleoclimatic records has improved our knowledge of the Earth's orbital variations in the past.
Biodiversity
[edit]
Unlike the vast multidirectional ocean currents in open oceans within their respective oceanic zones; biodiversity in the Mediterranean Sea is stable due to the subtle but strong locked nature of currents which is favourable to life, even the smallest macroscopic type of volcanic life form. The stable marine ecosystem of the Mediterranean Sea and sea temperature provides a nourishing environment for life in the deep sea to flourish while assuring a balanced aquatic ecosystem excluded from any external deep oceanic factors. It is estimated that there are more than 17,000 marine species in the Mediterranean Sea with generally higher marine biodiversity in coastal areas, continental shelves, and decreases with depth.<ref>Coll, Marta, et al., "The biodiversity of the Mediterranean Sea: estimates, patterns, and threats". PLOS ONE 5.8, 2010.</ref>
As a result of the drying of the sea during the Messinian salinity crisis,<ref>Hsu K.J., "When the Mediterranean Dried Up" Scientific American, Vol. 227, December 1972, p. 32</ref> the marine biota of the Mediterranean is derived primarily from the Atlantic Ocean. The North Atlantic is considerably colder and more nutrient-rich than the Mediterranean, and the marine life of the Mediterranean has had to adapt to its differing conditions in the five million years since the basin was reflooded.
The Alboran Sea is a transition zone between the two seas, containing a mix of Mediterranean and Atlantic species. The Alboran Sea has the largest population of bottlenose dolphins in the Western Mediterranean, is home to the last population of harbour porpoises in the Mediterranean and is the most important feeding grounds for loggerhead sea turtles in Europe. The Alboran Sea also hosts important commercial fisheries, including sardines and swordfish. The Mediterranean monk seals live in the Aegean Sea in Greece. In 2003, the World Wildlife Fund raised concerns about the widespread drift net fishing endangering populations of dolphins, turtles, and other marine animals such as the spiny squat lobster.
There was a resident population of orcas in the Mediterranean until the 1980s, when they went extinct, probably due to long-term PCB exposure. There are still annual sightings of orca vagrants.<ref>Carrington, Damian. "UK's last resident killer whales 'doomed to extinction'" Template:Webarchive, The Guardian, London, 14 January 2016. Retrieved 17 February 2019.</ref>
Environmental issues
[edit]For 4,000 years, human activity has transformed most parts of Mediterranean Europe, and the "humanisation of the landscape" overlapped with the appearance of the present Mediterranean climate.<ref name="Yale" /> The image of a simplistic, environmental determinist notion of a Mediterranean paradise on Earth in antiquity, which was destroyed by later civilisations, dates back to at least the 18th century and was for centuries fashionable in archaeological and historical circles. Based on a broad variety of methods, e.g. historical documents, analysis of trade relations, floodplain sediments, pollen, tree-ring and further archaeometric analyses and population studies, Alfred Thomas Grove's and Oliver Rackham's work on "The Nature of Mediterranean Europe" challenges this common wisdom of a Mediterranean Europe as a "Lost Eden", a formerly fertile and forested region, that had been progressively degraded and desertified by human mismanagement.<ref name="Yale" /> The belief stems more from the failure of the recent landscape to measure up to the imaginary past of the classics as idealised by artists, poets and scientists of the early modern Enlightenment.<ref name="Yale" />
The historical evolution of climate, vegetation and landscape in southern Europe from prehistoric times to the present is much more complex and underwent various changes. For example, some of the deforestation had already taken place before the Roman age. While in the Roman age large enterprises such as the latifundia took effective care of forests and agriculture, the largest depopulation effects came with the end of the empire. SomeTemplate:Who assume that the major deforestation took place in modern times—the later usage patterns were also quite different e.g. in southern and northern Italy. Also, the climate has usually been unstable and there is evidence of various ancient and modern "Little Ice Ages",<ref>Jean M. Grove (2004). Little Ice Ages: Ancient and Modern. Taylor & Francis.</ref>Template:Page needed and plant cover accommodated to various extremes and became resilient to various patterns of human activity.<ref name="Yale" />
Even Grove considered that human activity could be the cause of climate change. Modern science has been able to provide clear evidence of this. The wide ecological diversity typical of Mediterranean Europe is predominantly based on human behaviour, as it is and has been closely related to human usage patterns.<ref name="Yale" /> The diversity rangeTemplate:Clarify was enhanced by the widespread exchange and interaction of the longstanding and highly diverse local agriculture, intense transport and trade relations, and the interaction with settlements, pasture and other land use. The greatest human-induced changes, however, came after World War II, in line with the "1950s syndrome"<ref>Christian Pfister (editor), Das 1950er Syndrom: Der Weg in die Konsumgesellschaft, Berne 1995</ref> as rural populations throughout the region abandoned traditional subsistence economies. Grove and Rackham suggest that the locals left the traditional agricultural patterns and instead became scenery-setting agentsTemplate:Clarify for tourism. This resulted in more uniform, large-scale formationsTemplate:Fix.<ref name="Yale" /> Among further current important threats to Mediterranean landscapes are overdevelopment of coastal areas, abandonment of mountains and, as mentioned, the loss of variety via the reduction of traditional agricultural occupations.<ref name="Yale" >The Nature of Mediterranean Europe: An Ecological History, by Alfred Thomas Grove, Oliver Rackham, Yale University Press, 2003, review at Yale university press Template:Webarchive Nature of Mediterranean Europe: An Ecological History (review) Template:Webarchive, Brian M.

Natural hazards
[edit].jpg){kind=link}
The Mediterranean region is one of the most geologically active maritime area of the globe, sitting on a complex tectonic boundary zone between the European and African plates. The geology of the region, with the presence of plate boundaries and active faults, makes it prone to quite frequent earthquakes, tsunamis and submarine landslides with can have devastating consequences in densely populated coastal areas. In addition climate change now intensifies the frequency and impacts of storm surges and coastal flooding, putting additional human lives and property at risk.<ref>Marine hazards and coastal vulnerabilities in the Mediterranean - realities and perceptions. 2024. pp. 5–25 in ’’ CIESM Monograph 52’’ (F. Briand, Ed.) ISSN 1726-5886 [3]</ref>
Earthquakes are relatively frequent in the Mediterranean Basin, ranking among the most damaging geohazards. One of the most destructive was the Crete earthquake in 365 BC, with Mw > 8, which lifted the western tip of the island by up to 9 m and caused a mega tsunami that destroyed many harbors in the eastern sub-basin.
Volcanic eruptions are not uncommon either and left their mark in historical and archaeological records. The largest include the Thera eruption, dated around 1600 BC, and the eruptions of Mount Vesuvius in 217 BC and AD 79 - the latter famously known for the destruction and the burying of the ancient cities of Pompeii and Herculaneum.<ref name=mcguire2003>Template:Cite news</ref> In the same region the Phlegraean Fields west of Naples constitute one of the most significant volcanic systems in the world, still very active. In the same general area, volcanoes like Mt. Etna and Stromboli are considered in a state of permanent activity, with frequent eruptions and lava emissions through the past 1500 years.
Tsunamis, usually triggered by earthquakes, volcanic eruptions and submarine landslides, have caused a number of documented disasters in the Mediterranean Basin in the past 2500 years. Historical examples include the 365 and 1303 tsunamis in the Hellenic Arc, more recently the disastrous 1908 event that destroyed the cities of Messina and Reggio Calabria, and the large tsunami that occurred off the Algerian margin in 2003.
On the diplomatic front, the experience of coastal countries and regional authorities is leading to exchangeTemplate:Fix at the international level with the cooperation of NGOs, states, regional and municipal authorities.<ref name=evch>Template:Cite web</ref> The Greek–Turkish earthquake diplomacy is a quite positive example of natural hazards leading to improved relations between traditional rivals in the region after earthquakes in İzmit and Athens in 1999. The European Union Solidarity Fund (EUSF) was set up to respond to major natural disasters and express European solidarity to disaster-stricken regions within all of Europe.<ref>Template:Cite web</ref> The largest amount of funding requests in the EU relates to forest fires, followed by floods and earthquakes. Forest fires, whether human-made or natural, are a frequent and dangerous hazard in the Mediterranean region.<ref name=evch/> Tsunamis are also an often-underestimated hazard in the region. For example, the 1908 Messina earthquake and tsunami took more than 123,000 lives in Sicily and Calabria and were among the deadliest natural disasters in modern Europe.
Invasive species
[edit]
The opening of the Suez Canal in 1869 created the first salt-water passage between the Mediterranean and the Red Sea. The Red Sea is higher than the Eastern Mediterranean, so the canal functions as a tidal strait that pours Red Sea water into the Mediterranean. The Bitter Lakes, which are hyper-saline natural lakes that form part of the canal, blocked the migration of Red Sea species into the Mediterranean for many decades, but as the salinity of the lakes gradually equalised with that of the Red Sea, the barrier to migration was removed, and plants and animals from the Red Sea have begun to colonise the Eastern Mediterranean. The Red Sea is generally saltier and more nutrient-poor than the Atlantic, so the Red Sea species have advantages over Atlantic species in the salty and nutrient-poor Eastern Mediterranean. Accordingly, Red Sea species invade the Mediterranean biota, and not vice versa; this phenomenon is known as the Lessepsian migration (after Ferdinand de Lesseps, the French engineer) or Erythrean ("red") invasion. The construction of the Aswan High Dam across the Nile River in the 1960s reduced the inflow of freshwater and nutrient-rich silt from the Nile into the Eastern Mediterranean, making conditions there even more like the Red Sea and worsening the impact of the invasive species.
Invasive species have become a major component of the Mediterranean ecosystem and have serious impacts on the Mediterranean ecology, endangering a number of local and endemic Mediterranean species. A first look at some groups of marine species shows that over 70% of exotic decapods<ref name="Briand">Template:Cite book</ref> and some 2/3 of exotic fishes<ref>Template:Cite web</ref> found in the Mediterranean are of Indo-Pacific origin, introduced from the Red Sea via the Suez Canal. This makes the Canal the first pathway of arrival of alien species into the Mediterranean. The impacts of some Lessepsian species have proven to be considerable, mainly in the Levantine basin of the Mediterranean, where they are replacing native species and becoming a familiar sight.
According to definitions by the Mediterranean Science Commission and the International Union for Conservation of Nature, and to Convention on Biological Diversity (CBD) and Ramsar Convention terminologies, they are alien species, as they are non-native (non-indigenous) to the Mediterranean Sea, and are found outside their normal, non-adjacent area of distribution. When these species succeed in establishing populations in the Mediterranean Sea, compete with and begin to replace native species they are "Alien Invasive Species", as they are an agent of change and a threat to the native biodiversity. In the context of CBD, "introduction" refers to the movement by human agency, indirect or direct, of an alien species outside of its natural range (past or present). The Suez Canal, being an artificial (human-made) canal, is a human agency. Lessepsian migrants are therefore "introduced" species (indirect, and unintentional). Whatever wording is chosen, they represent a threat to the native Mediterranean biodiversity, because they are non-indigenous to this sea. In recent years, the Egyptian government's announcement of its intentions to deepen and widen the Canal<ref>Template:Cite web</ref> raised concerns from marine biologists, fearing that such an act will only worsen the invasion of Red Sea species into the Mediterranean, and lead to even more species passing through the Canal.<ref>Template:Cite book</ref>
Arrival of new tropical Atlantic species
[edit]In recent decades, the arrival of exotic species from the tropical Atlantic has become noticeable. In many cases this reflects an expansion – favoured by a warming trend of sub-tropical Atlantic waters, and also by a fast-growing maritime traffic – of the natural range of species that now enter the Mediterranean through the Strait of Gibraltar. While not as intense as Lessepsian migration, the process is of importance and is therefore receiving increased levels of scientific coverage.<ref>Template:Cite book</ref>
Sea-level rise
[edit]By 2100 the overall level of the Mediterranean could rise between Template:Convert as a result of the effects of climate change.<ref>Template:Cite web</ref> This could have adverse effects on populations across the Mediterranean:
- Rising sea levels will submerge parts of Malta. Rising sea levels will also mean rising salt water levels in Malta's groundwater supply and reduce the availability of drinking water.<ref>Template:Cite news</ref>
- A Template:Convert rise in sea level would flood Template:Convert of the Nile Delta, displacing over 500,000 Egyptians.<ref>Template:Cite web</ref>
- Cyprus wetlands are also in danger of being destroyed by the rising temperatures and sea levels.<ref>Template:Cite web</ref>
Coastal ecosystems also appear to be threatened by sea level rise, especially enclosed seas such as the Baltic, the Mediterranean and the Black Sea. These seas have only small and primarily east–west movement corridors, which may restrict northward displacement of organisms in these areas.<ref>Nicholls, R.J.; Klein, R.J.T. (2005).

Pollution
[edit]Pollution in this region has been extremely high in recent years.Template:When The United Nations Environment Programme has estimated that Template:Convert of sewage, Template:Convert of mineral oil, Template:Convert of mercury, Template:Convert of lead and Template:Convert of phosphates are dumped into the Mediterranean each year.<ref>Template:Cite web</ref> The Barcelona Convention aims to 'reduce pollution in the Mediterranean Sea and protect and improve the marine environment in the area, thereby contributing to its sustainable development.'<ref>Template:Cite web</ref> Many marine species have been almost wiped out because of the sea's pollution. One of them is the Mediterranean monk seal which is considered to be among the world's most endangered marine mammals.<ref>Template:Cite web</ref> The Mediterranean is also plagued by marine debris. A 1994 study of the seabed using trawl nets around the coasts of Spain, France and Italy reported a particularly high mean concentration of debris; an average of 1,935 items per km2 (Template:Convert).<ref name="nep.org/regionalseas/ma">Template:Cite web</ref>
Shipping
[edit]
Some of the world's busiest shipping routes are in the Mediterranean Sea. In particular, the Maritime Silk Road from Asia and Africa leads through the Suez Canal directly into the Mediterranean Sea to its deep-water ports in Valencia, Piraeus, Trieste, Genoa, Marseille and Barcelona. It is estimated that approximately 220,000 merchant vessels of more than 100 tonnes cross the Mediterranean Sea each year—about one-third of the world's total merchant shipping. These ships often carry hazardous cargo, which if lost would result in severe damage to the marine environment.
The discharge of chemical tank washings and oily wastes also represent a significant source of marine pollution. The Mediterranean Sea constitutes 0.7% of the global water surface and yet receives 17% of global marine oil pollution. It is estimated that every year between Template:Convert of crude oil are deliberately released into the sea from shipping activities.
Approximately Template:Convert of oil are transported annually in the Mediterranean Sea (more than 20% of the world total), with around 250–300 oil tankers crossing the sea every day. An important destination is the Port of Trieste, the starting point of the Transalpine Pipeline, which covers 40% of Germany's oil demand (100% of the federal states of Bavaria and Baden-Württemberg), 90% of Austria and 50% of the Czech Republic.<ref>Thomas Fromm "Pipeline durch die Alpen: Alles im Fluss" In: Süddeutsche Zeitung, 26 December 2019.</ref> Accidental oil spills happen frequently with an average of 10 spills per year. A major oil spill could occur at any time in any part of the Mediterranean.<ref name="greenpeace.org"/>
Tourism
[edit]
The coast of the Mediterranean has been used for tourism since ancient times, as the Roman villa buildings on the Amalfi Coast or in Barcola show. From the end of the 19th century, in particular, the beaches became places of longing for many Europeans and travellers. From then on, and especially after World War II, mass tourism to the Mediterranean began with all its advantages and disadvantages. While initially, the journey was by train and later by bus or car, today the plane is increasingly used.<ref>Rüdiger Hachtmann "Tourismus-Geschichte". (2007); Attilio Brilli "Quando viaggiare era un'arte. Il romanzo del grand tour." (1995).</ref>
Tourism is today one of the most important sources of income for many Mediterranean countries, despite the human-made geopolitical conflictsTemplate:Clarify in the region. The countries have tried to extinguish rising human-made chaotic zonesTemplate:Clarify that might affect the region's economies and societies in neighbouring coastal countries, and shipping routes. Naval and rescue components in the Mediterranean Sea are considered to be among the bestTemplate:Citation needed due to the rapid cooperation between various naval fleets. Unlike the vast open oceans, the sea's closed position facilitates effective naval and rescue missionsTemplate:Citation needed, considered the safestTemplate:Citation needed and regardless ofTemplate:Clarify any human-made or natural disaster.<ref>Template:Cite web</ref>
Tourism is a source of income for small coastal communities, including islands, independent of urban centres. However, tourism has also played a major role in the degradation of the coastal and marine environment. Rapid development has been encouraged by Mediterranean governments to support the large numbers of tourists visiting the region, but this has caused serious disturbance to marine habitats by erosion and pollution in many places along the Mediterranean coasts.
Tourism often concentrates in areas of high natural wealthTemplate:Clarify, causing a serious threat to the habitats of endangered species such as sea turtles and monk seals. Reductions in natural wealth may reduce the incentive for tourists to visit.<ref name="greenpeace.org"/>
Overfishing
[edit]Template:Main Fish stock levels in the Mediterranean Sea are alarmingly low. The European Environment Agency says that more than 65% of all fish stocks in the region are outside safe biological limits and the United Nations Food and Agriculture Organisation, that some of the most important fisheries—such as albacore and bluefin tuna, hake, marlin, swordfish, red mullet and sea bream—are threatened.Template:Date missing
There are clear indications that catch size and quality have declined, often dramatically, and in many areas, larger and longer-lived species have disappeared entirely from commercial catches.
Large open-water fish like tuna have been a shared fisheries resource for thousands of years, but the stocks are now dangerously low. In 1999, Greenpeace published a report revealing that the amount of bluefin tuna in the Mediterranean had decreased by over 80% in the previous 20 years, and government scientists warn that without immediate action, the stock will collapse.
Marine heatwaves
[edit]Template:Main A study showed that climate change-related exceptional marine heatwaves in the Mediterranean Sea during 2015–2019 resulted in widespread mass sealife die-offs in five consecutive years.<ref>Template:Cite news</ref><ref>Template:Cite journal</ref>
