Bottom topography - assessed by swath bathymetry - of the Southern Ocean collected aboard the James Clark Ross (JR145) during the 2005-2006 field season.
Bathymetry data was collected to assess its influence on dispersal and gene flow in two Antarctic fishes (Champsocephalus gunnari and Notothenia rossii). Data was collected in the Southern Ocean from Elephant Island, Deception Island, the South Orkney Islands, King George (Potter Cove) and Signy (Borge Bay).
