| Summary: | 9 pages, 5 figures, 1 table During an Antarctic survey carried out on board the R/V “Professor Siedlecki” (26 December 1988–18 January 1989) seawater samples were collected from nine depths, from the surface to 150 m, at 29 stations near the pack-ice in a zone of the Weddell—Scotia Confluence between Elephant Island and the South Orkney Islands. The samples were analyzed for total organic carbon (TOC) and silicate concentrations. The two main water masses in the sampling area, coming from the Drake Passage and Weddell Sea, are well-defined using silicate as a tracer. The concentrations of TOC are higher than 100 μM and are associated with low silicate concentrations. However, in the deep water influenced by the Weddell Sea the concentrations of TOC are about 30 μM. Peer reviewed |
