5. Ross Sea Biodiversity, Part I: validation of the 2007 CCAMLR Bioregionalisation Workshop results towards including the Ross Sea in a representative network of marine protected areas in the Southern Ocean

   Abstract:  This report provides the scientific basis, validating the results of the CCAMLR ... Bioregionalization Workshop (2007) as well as the report of ASOC (2010), for identifying the Ross Sea as one of 11 ... areas deserving close scrutiny for inclusion in a network of marine protected areas. CCAMLR (2007 ... ) identified the Ross Sea as an area of high biodiversity on the basis of its high physical heterogeneity; ASOC ...

6. Further analysis of spatial patterns of benthic invertebrate habitats from fishery bycatch in the Ross Sea region

   presence of VME taxa bycatch are identifiable, as are several areas of dense fishing effort with no ... evidence of VME taxa. Identifiable sponge and/or gorgonian habitats occurred at a typical scale of 10-30 km ... , but were at larger scales. Spatial analysis of these data allows the detectability of prevalent taxa ... to be estimated, along with changes in catch rate at different levels of observed bycatch. Results ...
