=== Northernmost land ===
{{Main|Northernmost point of land}}
The northernmost point of land on Earth was long thought to be [[Cape Morris Jesup]] at the northern tip of mainland Greenland. However, in 1969 a Canadian team surveyed [[Kaffeklubben Island]] (latitude 83°&nbsp;39′&nbsp;45″ N), which was first recorded in 1900 and first visited in 1921, and determined that its northernmost point is 750 m north of Cape Morris Jesup. It is thus the northernmost undisputed permanent land.<ref>{{Cite web |title=Kaffeklubben Island {{!}} Island in Arctic Circle, History |url=https://www.britannica.com/place/Kaffeklubben-Island |access-date=2024-12-27 |website=Britannica |language=en}}</ref>

Other points have been claimed to be the northernmost point, with dispute over the title arising from [[ice sheet]]s, water movement and inundation, and storm activity that may build, shift, or destroy banks of gravelly [[moraine]] material. In 1978 Uffe Petersen, a member of the [[Danish Geodesic Institute|Danish Geodetic Institute]], discovered [[Oodaaq|Oodaaq Island]] at 83°&nbsp;40'&nbsp;32.5"&nbsp;N. Its last confirmed sighting was in 1979.<ref>{{Cite web |last=Jancik |first=John |date=2004 |title=Jensenland, historical timeline of the search for the northernmost point of land on Earth |url=https://publications.americanalpineclub.org/articles/12200425000/Jensenland-Historical-Timeline-of-the-Search-for-the-Northernmost-Point-of-Land-on-Earth |access-date=2024-12-27 |website=American Alpine Club}}</ref> In 2003, a small protrusion of rocks and boulders, {{convert|35|x|15|m|abbr=on}} in length and width, was discovered by Arctic explorer [[Dennis Schmitt]] and his team at latitude 83°&nbsp;42'&nbsp;N and unofficially named [[83-42]].<ref>{{Cite web |last=Burress |first=Charles |date=2004-06-17 |title=BERKELEY / Romancing the north / Berkeley explorer may have stepped on ancient Thule |url=https://www.sfgate.com/bayarea/article/BERKELEY-Romancing-the-north-Berkeley-2748730.php |access-date=2024-12-27 |website=SFGATE |language=en}}</ref> Whether this land is permanent is uncertain; a 2022 bathymetric survey determined that it was likely ''not'' connected to the seafloor, but rather rocky material on top of sea ice, and thus not land.<ref>{{Cite web |date=2022-09-25 |title=The 'Northernmost Island in the World' is actually an iceberg |url=https://www.leister-group.com/en/Stories/2022-15-09-LAG-Greenland-Expedition-2022 |access-date=2024-12-27 |website=LeisterGroup |language=en}}</ref>
