The Antarctic continental margins, where precursors to Antarctic Bottom Water are pre-conditioned, are critical but under-observed regions for physical processes affecting global climate. As the major UK contribution to the International Polar Year project SASSI (Synoptic Antarctic Shelf-Slope Interactions), a moored array was deployed from February 2009 to February 2010 across the continental shelf and slope of the southeast Weddell Sea. High vertical resolution sections were obtained from lowered instruments during the mooring deployment and recovery. The moored and lowered instrumentation measured pressure, temperature, salinity and velocity. A preliminary analysis of these observations will be shown to characterize the temporal variability and dynamics of the Antarctic Slope Front and associated currents in this area.
