To assist marine protected area planning within the Del Cano- Crozet planning domain, we have collated available data and described important environmental features for this domain. At the Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR) marine protected area workshop held in Brest, France in 2011, scientists adopted nine domains to plan for and assess progress towards a representative system of MPAs within the Southern Ocean surrounding Antarctica. The Del Cano- Crozet domain is located in eastern Antarctica (between 30-60 degrees east) with a northern border of 45 degrees south. The data summarised includes the environmental drivers that influence the distribution of Southern Ocean biota, biological data and previous classifications of the benthic and pelagic environments. Existing protected areas are also outlined. This research was completed for WWF’s Antarctic & Southern Ocean Initiative with funding provided by WWF Sweden’s Project Ocean.
