Large Marine Ecosystems (LMEs) are regions of the world's oceans, encompassing coastal areas from river basins and estuaries to the seaward boundaries of continental shelves and the outer margins of the major ocean current systems, and/or occupying semi-enclosed seas. LMEs typically cover relatively large areas, characterized by distinct bathymetry, hydrography, productivity, and trophically dependent populations of marine species1. Globally, 66 different LMEs have been delineated.
