R/V BILIM LEG-1 CRUISE
Duration of the cruise:09 Sept. 1999 - 17 Sept. 1999
|
Basic aims of this joint venture are |
 |
to determine the in-situ overall kinetic rate constants of the H2S oxidation and/or of its removal processes, and to understand the factors responsible for the observed rate constants and roles of nitrate on it within the sub-oxic layer of the Black Sea |
|
to test the hypotheses suggested for the role of the nitrate diffusing from the water masses located at the upper layer of the SOZ (Sub-oxic Zone) into the SOZ on the removal of hydrogen sulfide. |
|
to determine the nitrogen removal rates and factors responsible for the removal (denitrification) of nitrate within different layers of the sub-oxic zone of the Black Sea. Detailed profiling of the water column for N2/Ar ratio measurements at selected stations. |
Field studies and measurements were performed at total of 29 stations in the south western Black Sea.
