(Table 2) Particulate organic carbon concentrations in the water column of the Barents Sea in August-September 1997

A comparative estimation of particulate organic matter concentration in seawater in various regions of the Barents Sea was carried out on the basis of materials collected by authors in August-September 1997. It is shown that the major feature of near-bottom distribution of particulate organic matter is distinct decrease in its concentration from off-shore areas of the Murman and Novaya Zemlya coasts and the Franz Josef Land Archipelago toward the central part of the Barents Sea. Using a method of mean and maximum concentrations of particulate organic matter, an attempt was made to estimate its fluxes from the surface to the bottom.

(Table 2) Abundance and biomass of zooplankton in the eastern Black Sea in the beginning of September 1996

On the basis of analyses of samples collected in the eastern Black Sea in September 1996 trends of increase in surface zooplankton biomass and general decrease in Mnemiopsis biomass were revealed.
