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. USERS PLEASE NOTE - shapefile does NOT accurately represent outer MEOW boundaries: As specified in the original publications, the boundaries in this shapefile have been extended out some 200 nautical miles from land (and this buffer is extended to include any additional marine areas less than 200metres in depth which lie beyond this distance). 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. A version of the shapefile cut to shelf areas will be released on this site by December 2007.

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.
