Collaborative Research: Pathways of Circumpolar Deep Water to West Antarctica from Profiling Float and Satellite MeasurementsCurrent oceanographic interest in the interaction of relatively warm water of the Southern Ocean Circumpolar Deep Water ( CDW) as it moves southward to the frigid waters of the Antarctic continental shelves is based on the potential importance of heat transport from the global ocean to the base of continental ice shelves. This is needed to understand the longer term mass balance of the continent,

OMG Swath Gridded Multibeam Echo Sounding (MBES) BathymetryThis dataset contains level 2 in situ depth measurements from Multibeam Echo Sounder System (MBES) instruments. These depths were used to map the bathymetry around ocean terminating glaciers of Greenland. The bathymetry mapping is part of the Oceans Melting Greenland (OMG) project. The goal of the project is to find out what contributions the ocean has on Greenland's melting glaciers. The MBES was

NSFGEO-NERC: Evolutionary Response of Southern Ocean Diatoms to Environmental ChangeThe research will examine how diatoms (an important group of plankton in the Southern Ocean) adapt to environmental change. Diatoms will be sampled from different regions of the Southern Ocean, including the Drake Passage, the Pacific Sector of the Southern Ocean and the Ross Sea and examined to determine the range of genetic variation among diatoms in these regions. Experiments on a range of diat

Floe-scale maps of sea ice draft from AUV multibeam on SIPEX-IIThese data were collected on the SIPEX II voyage of the Aurora Australis in 2012. These data are floe-scale maps of Antarctic sea ice draft (m). These were collected using a multibeam instrument attached to an autonomous underwater vehicle (AUV). This AUV was the WHOI 'SeaBED-class' vehicle named 'Jaguar'. Details on the deployment and processing of this data can be found in Williams, Maksym and W
