DISSOLVED AND SUSPENDED PARTICULATE ORGAN IC-MATTER IN ANTARCTIC WATERS OF THE ATLANTIC-OCEAN

On the basis of 332 analyses of dissolved (DOS) and particulate organi c carbon (POC) taken from the surface to 4785 m depth at 10 stations o f the Atlantic part of the Antarctic Ocean, the following regularities were determined: low DOC concentrations, a sharp decrease in the uppe r 40 - 120 m layer, small variability values in the Antarctic divergen ce zone, the lack of correlation between DOC and phytoplankton primary production. A decrease in depth of average POC concentrations with a small gradient in the 0 - 200 m water layer, an increase of POC concen trations in the pycnocline and during phytoplankton bloom were found. The Antarctic Ocean is characterized, as a whole, by small POC concent rations close to the average values for the World Ocean. Analysis of t he measurements of variations of DOC and POC concentrations made on th e ship's route in the surface layers of the Indian and the Atlantic oc eans was considered.
