PurposeResearch
ObjectivesES033 undertook physical oceanographic activities in the northern Weddell Sea (near the South Orkney Islands, and in the southern Weddell Sea, in the general area of Brunt Ice Shelf. Four projects were served by the cruise:

1. Long Term Monitoring and Survey (LTMS) component (British Antarctic Survey (BAS), Lamont Doherty Earth Observatory (LDEO) and Bjerknes Centre for Climate Research, University of Bergen (BCCR))
2. SASSI-UK project (University of East Anglia (UEA), BAS and the Scottish Association of Marine Science (SAMS))
3. ACES-FOCAS BAS core project (BAS and University of California, Santa Cruz)
4. IPY project Bi-Polar Atlantic Thermohaline Circulation (BIAC). (University of Bergen)

Objective of the IPY-BIAC participants is to conduct a study of the cold and heavy plume of ice shelf water as it traverses and descends the continental slope north of the Filchner-Ronne continental shelf. The principal tools are a microstructure profiler, hydrography and current profiling, and the deployment of five over-wintering moorings. Due to ice conditions, plume site was not visited, however, turbulence, hydrography and current profiling and mooring deployment were made in the eastern Weddell Sea to study the mixing processes over the continental shelf and continental shelf break.
