The Impacts of Deglaciation on Benthic Marine Ecosystems in Antarctica (ICEBERGS) dataset comprises of physical oceanography, marine geology, habitat mapping, community structure and seabed sediment data. The data were collected from CTD deployments, multi-beam swath bathymetry surveys, TOPAS sub-bottom profiling, shallow underwater camera system deployments, plankton net deployments, Agassiz trawls, Hamon grabs and multi-corer deployments during three seasonal cruises around the West Antarctic Peninsula beginning 2017 and scheduled to end in 2021. The data were collected as part of the ICEBERGS project to investigate the impacts of physical disturbance arising from climate-warming induced deglaciation on benthic communities around the West Antarctic Peninsula. The ICEBERGS project is part of the joint funded NERC-CONICYT Initiative and involves collaboration between the University of Exeter, University of Bangor, British Antarctic Survey (BAS) and Universidad Católica de la Santísima Concepción. The physical data will be managed by the British Oceanographic Data Centre (BODC) with the remainder of the data being submitted to the Polar Data Centre (BAS-PDC).
