r/v"Akvanavt" cruise to the North-Eastern Black Sea in November 12-18, 1997


During the expedition there were obtained data on:
Temperature, Salinity, Transparency, Dissolved Oxygen, NO3, NO2, NH4, H2S(iod.), H2S (phot.), dissolved Mn. and CH4 for the depth levels 0 -2150 m. The particulate matter samples were collected at the Nepheloid Redox Layer depths. We were lucky with weather and were able to work all the period of cruise. In the Map above only the Stations with hydrochemical data sampling are shown.
