AbstractA detailed study of organic carbon content obtained from two sediment cores collected in the Joides basin, western Ross Sea, Antarctica, was carried out. The variations observed during the last deglaciation and the Holocene were compared to the high-resolution climatic records (EPICA DC and Taylor Dome) preserved in the ice. The importance of the carbon content as a proxy for palaeoclimatic and palaeoenvironmental changes was investigated. A dramatic decrease in the Ross Sea palaeoproductivity was observed during the Antarctic Cold Reversal (12.5–14 kyr BP). Another decrease in total organic carbon in the second half of the Holocene (after 5–6 kyr BP) confirms the climate worsening observed in previous studies.

The present work aimed at investigating the effects of growing eutrophic conditions and soil occupation on the carbon storage in Guanabara Bay. Sterols in dated sediment cores were used to characterize the sources of organic matter to the bay. Dinosterol was the most abundant amongst the measured sterols reaching 64.7 % of the total. Coprostanol, a fecal sterol, was present in concentrations as high as 40 µg g-1 in areas of intensive sewage discharge. These results are in agreement with the known elevated primary production in the bay and with the severe eutrophic conditions. The calculated carbon fluxes using the organic carbon content and the sedimention rates range between 50 g C m-2 year-1 and 500g C m-2 year-1 during the last 100 years.
