Non ecoregional based, but 18 marine biopolitical regions were defined. Seeks to define a global representative system of protected areas.
Experts working groups and regional workshops.
Available information on existing and proposed protected areas, lacks data- driven rigor.
Only limited comparatives can be made between these marine priority setting exercises, due to the lack of other ecoregional cartography based works. Nevertheless the Global 200 defines marine globally important ecoregions and some of the conclusions of the GBRMPA - The World Bank - IUCN, 1995 exercise (Kelleher et al., 1995) conclusions can be safely extrapolated to an ecoregional level.
Type of Approach
Basic quantitative data used where available, complemented by qualitative joint expert on the spot assessments. Qualitative expert assessments, lacks data-driven rigor.

Athough the different exercises are quite dissimilar, the large expanses covered by the marine ecoregions, results in a coherent result from the comparasion.
