Marine Ecoregions of the World (MEOW) is a biogeographic classification of the world's coasts and shelves. It is the first ever comprehensive marine classification system with clearly defined boundaries and definitions and was developed to closely link to existing regional systems. The ecoregions nest within the broader biogeographic tiers of Realms and Provinces. MEOW represents broad-scale patterns of species and communities in the ocean, and was designed as a tool for planning conservation across a range of scales and assessing conservation efforts and gaps worldwide. The current system focuses on coast and shelf areas and does not consider realms in pelagic or deep benthic environment. It is hoped that parallel but distinct systems for pelagic and deep benthic biotas will be devised in the near future. The project was led by WWF and The Nature Conservancy, with broad input from a working group representing key NGO, academic and intergovernmental conservation partners. This classification represents a new work, derived by a team representing various conservation NGOs and acadamics. It is partly derived from existing classifications. The layer provides a geographic framework for a broad range of analyses relating to biodiversity (including measures of condition, threat, and conservation progress) in the marine environment.

This outer boundary buffer is primarily drawn here to ease visibility of ecoregions in global and regional scale maps. Similarly the inland boundaries of the ecoregions extend far inland - a convention to ensure inclusion of any coastline and estuarine/lagoonal systems which may be derived from different map sources. As specified, the ecoregional classification relates primarily to coast and shelf biotas for which a 200m depth contour is a more accurate indicative boundary. It is therefore not an appropriate use of the data to calculate total ecoregion areas or generate other area or volumetric dependent statistics using these boundaries alone.

The classification is largely based on existing regional classifications and there is some variance in the approaches used by the original authors although every effort was made to develop an internally consistent report and to reject sources that were not in accord with the definitions developed and presented in Spalding et al 2007.
