Editing Oil spill (section)

=== Usage and application ===
The ESI depicts environmental stability, coastal resilience to maritime related catastrophes, and the configurations of a stress-response relationship between all things maritime.<ref>{{Cite journal|last=Buckley|first=R.C.|date=1982|title=Environmental sensitivity mapping – what, why and how|journal=Minerals and the Environment|volume=4|issue=4|pages=151–155|doi=10.1007/BF02085976|bibcode=1982MinEn...4..151B |s2cid=129097590}}</ref> Created for ecological-related decision making, ESMs can accurately identify sensitive areas and habitats, clean-up responses, response measures and monitoring strategies for oil-spills.<ref>{{Cite book|last=van Bernem|first=Karl-Heinz|title=Models in Environmental Research|publisher=Springer|year=2001|pages=127–145|chapter=Chapter 7: Conceptual Models for Ecology-Related Decisions}}</ref> The maps allow experts from varying fields to come together and work efficiently during fast-paced response operations. 
The process of making an ESI atlas involves GIS technology. The steps involve, first zoning the area that is to be mapped, and secondly, a meeting with local and regional experts on the area and its resources.<ref name=":7">IPIECA, IMO, OGP. (2012). ''Sensitivity mapping for oil spill response'' (OGP Report Number 477).</ref> Following, all the shoreline types, biological, and human use resources need to be identified and their locations pinpointed. Once all this information is gathered, it then becomes digitized. In its digital format, classifications are set in place, tables are produced and local experts refine the product before it gets released.

ESI's current most common use is within contingency planning. After the maps are calculated and produced, the most sensitive areas get picked out and authenticated. These areas then go through a scrutinization process throughout which methods of protection and resource assessments are obtained.<ref name=":7" /> This in-depth research is then put back into the ESMs to develop their accuracy and allowing for tactical information to be stored in them as well. The finished maps are then used for drills and trainings for clean-up efficiency.<ref name=":7" /> Trainings also often help to update the maps and tweak certain flaws that might have occurred in the previous steps.
