Southern Ocean Benthic Classification (SOBC) - ecoregions, bathomes and environmental types
This dataset is intended for general use in spatial planning and management to identify areas where benthic marine assemblages are likely to differ from each other in the Southern Ocean. We achieve this by using a hierarchical spatial classification of ecoregions, bathomes and environmental types. E...

This dataset is intended for general use in spatial planning and management to identify areas where benthic marine assemblages are likely to differ from each other in the Southern Ocean.

Ecoregions are defined according to available data on biogeographic patterns and environmental drivers on dispersal.
