Report of the Physical and Chemical Intercalibration of the April-May 1994 Data. (Joint TU-Black Sea and CoMSBlack cruises). Technical Report, IMS, METU, Erdemli, Turkey, 1995, 61pp.


The cruise planning program (appendix 1) for the CoMSBlack and TU-Black Sea joint cruise for 1994 was first discussed in detail during the NATO TU-Black Sea Working Group 2 meeting held in Erdemli in January of 1994 and finalized at the WHOI in February of 1994 during TU-Black Sea Working Group 1 and 2 representatives joint meeting. For this cruise, same as for the CoMSBlack 93'a cruise, the focus was on the onset of the Spring Plankton Bloom in the northwest Black Sea shelf, with supporting studies throughout the entire western Black Sea (west of the line connecting southern Crimea with Cape Sinop; approx. 34 E).

The Intercalibration and data exchange meeting for physical and biochemical data acquired during the 1994 cruise was held at the Institute of Marine Sciences/Middle East Technical University, Erdemli, Turkey, October 13 - 20, 1994.

The 1994 expedition acquired complete hydrographic and biochemical data set for the western part (west off 35řE) of the Black Sea with the participation from Turkey (IMS/METU) and Ukraine (MHI). 248 hydrographic stations were occupied to the water depth 500 - 2000 dbar or to the bottom over the shallower regions; biochemical measurements were made at 193 of these stations. This quasi-synoptic survey was accomplished by two ships during an interval of approximately two weeks.

Results reveal good agreement between CTD's of different brands (same as for the CoMSBlack '92a and CoMSBlack '93a cruise data), and the intercalibrated results show a consistent and high resolution detail of various physical characteristics of the western Black Sea basin. The intercalibrated data set is now available within each country and contributes to the basis for studies on marine physics as well as interdisciplinary issues.

The meeting resulted in the exchange and intercalibration of all the data, draft plans for future cruise (CoMSBlack and TU-Black Sea '95a) and outlines of scientific papers to be prepared in the nearest future which will be submitted to scientific journals.
