HYDROCHEMICAL PROCESSES IN THE SYSTEM OF JOINT MESOSCALE EDDIES ON THE SAKHALIN SHELF

The thorough survey of 1992 and 1993 showed a system of meso-scale edd ies on the Sakhalin shelf. The cyclonic eddies were observed at the sh allow water of the shelf, while the anticyclonic ones were located in the open sea at boundary of the shelf. The peculiarities of the hydroc hemical structure, as well as of the production and destruction proces ses were studied in the zone. Primary production was estimated by nutr ient consumption, dissolved oxygen output, and the increase of the con tent of organic compounds of nitrogen and phosphorus.
