Moored measurements of current, temperature and salinity in the southern Weddell Sea, January 2009-January 2010

The data set was collected as a part of the International Polar Year project entitled “Bipolar Atlantic Thermohaline Circulation (BIAC)”, under the working theme “Downslope processes, pathways, cascading and mixing”. The objective was to study the dynamics and mixing of the dense overflow plume on the continental slope of the Weddell Sea northwest of Filchner Depression.

Due to difficult ice conditions, the Filchner outflow site could not be accessed. Moorings were instead deployed on the southeastern Weddell Sea, on the central Crary Fan and further to the east. The positions were chosen to capture the variability associated with the slope current in the region, basin-shelf exchange as well as the tidal band variability.
