Oceans and divisions in Ocean regions in AquaNIS:
Large Marine Ecosystems are extensive areas of ocean space of approximately 200,000 km² or greater, characterized by distinct hydrographic regimes, submarine topography, productivity, and trophically dependent populations, adjacent to the continents in coastal waters where primary productivity is generally higher than in open ocean areas (sensu Sherman and Duda, 1999). The map of LMEs and all accompanying information is publically assessable at the NOAA (2012) website. In addition to LMEs defined by NOAA, AquaNIS included the following LME-like areas to ensure better geographical coverage:
The list of countries is adopted from the UN Population Division's quinquennial estimates and projections (United Nations, 2012). All countries are linked to relevant LMEs or LME Sub-regions. This provides combinations "country + LME" or "country + LME sub-region" for different coasts and for a country that borders different seas, e.g.: "Germany within the LME 23 Baltic Sea", "Italy within the Adriatic Sea, a sub-region of LME 26 Mediterranean Sea". The arrangement enables entering and retrieving information at different user defined geographic scales.
