Large Marine Ecosystems (LMEs) are relatively large areas of ocean space of approximately 200,000 sq km; or greater, adjacent to the continents in coastal waters where primary productivity is generally higher than in open ocean areas. This Biogeographic Synthesis Composition takes an LME identifier as an input parameter and assemples a set of Biogeographic Analysis Packages that present information about the status and trends of biodiversity in the LME.
