The figure for leg 1 shows 7 transects with 3 stations each at the following water depths (300 m, 500 m, 1750 m). The central western gyre station of 2001 will be occupied to complete the three-dimensional mapping of the Bosporus plume. Microbiological (and other) incubation experiments for Mn, N and S cycling / transformations will be performed with samples from traditional CTD bottle casts. Biological and microbiological sampling can be accomplished from the CTD/rosette - net tows can also be performed. McLane pumps will be used to obtain suspended sediment samples for biomarker and microbial community structure analyses. We anticipate that each transect can be accomplished in 1 to 1.5 days. The priority will be for CTD and pump casts. ADCP data will be acquired during this leg to help provide a physical framework for the pump casts. R/V Knorr Black Sea cruise 2003- Voyage 172- Leg #8, Apr 25 to May 10 The primary goal of this leg is to do a detailed study of the suboxic zone in the eastern basin using in situ pump profiling and in situ voltammetry in coordination with CTD casts. A short trip to Sevastopol is also planned. We will sample the central western gyre station of 2001 and the central station of 1988. This will provide a detailed mapping of the suboxic zone in the western, central and eastern Black Sea. Microbiological (and other) incubation experiments for Mn, N and S cycling / transformations will be performed with samples from traditional CTD bottle casts. Biological and microbiological sampling can be accomplished from the CTD/rosette - net tows can also be performed. McLane pumps will be used to obtain suspended sediment samples for biomarker and microbial community structure analyses. Box cores near the Crimea will also be taken for biomarker and microbial community structure analyses. Sampling for inert gases will likely occur on this leg. A transect sequence into the far southeastern region of the Black Sea will be performed for detailed physical (CTD and ADCP) measurements for Temel Oguz to test his hypotheses on the eddies in that region. R/V Knorr Black Sea cruise 2003- Voyage 172- Leg #9- May10-15 This short leg will provide more time for sediment sampling and other types of sampling in the southwestern Black Sea that could not be accommodated in the first two legs. The pump profiler will not be available for this leg but in situ voltammetry will be available.
