Abstract The Cooperative East Antarctic Marine Census project (CEAMARC) survey was a collaborative survey involving 5 nations under the umbrella of the Census of Antarctic Marine Life (CAML). The CAML is an international program sponsored by the Sloan Foundation and is part of the overall Census of Marine Life. It is also an endorsed International Polar Year (IPY) project. The survey took place in December to January 2006- 2007 on the RSV Aurora Australis. The survey aims were 1. To collect biological samples and underwater video records of the seabed to document the fauna and communities associated with representative habitats. 2. To collect data on water properties and currents to document the oceanographic environment of the survey area. 3. To acquire sidescan data and sediments to describe the substrate types and environment of deposition for the various seabed habitats. Geoscience Australia provided sediment sampling equipment, sidescan sonar and underwater video equipment to provide physical data to support the biological sampling. In total, CEAMARC collected: #BL 130 conductivity-temperature- depth casts with sampling bottles #BL 87 AAD beam trawls #BL 13 French beam trawls #BL 6 sled trawls #BL 102 box corers #BL 3 Smith- MacIntyre grabs #BL 9 Van-Veen grabs #BL 5 continuous plankton recorder deployments #BL 25 Geoscience Australia Deep Underwater Camera deployments #BL 33 AAD video deployments #BL 39 AAD still camera deployments #BL 23 plankton water samples #BL 2 sidescan sonar deployments Sediment samples, GA video and sidescan sonar data are archived at GA. CEAMARC has provided a major new set of data to further the understanding of the Antarctic marine biodiversity and the relationship between physical conditions and benthic communities.
