Geochemical and Structural Aspects of the Pycnocline in the Black Sea (R/V KNORR 134-8 LEG 1, 1988)er water column in the Black Sea. Insitu TV inspection allowed us to discern - from top to bottom - three macrofauna zones in the oxygenated layer above the pycnocline: the . zone, the . zone and (existing only in coastal waters) the . zone. At a density of 16.1 to 16.4 ∑Θ a layer is present consist

Potential for Manganese(II) Oxidation and Manganese(IV) Reduction to Co-Occur in the Suboxic Zone ong leg 3 of the US-Turkey Black Sea Expedition in June 1988. A strong potential for both microbial Mn(II) oxidation and microbial Mn(IV) reduction was measured by radioactive incubation experiments and enrichment culture techniques, throughout the suboxic zone. Rates of .Mn(II) precipitation and .Mn

The Oxidation of H2S with O2 in the Black Sea,n rates were found to be ten times faster than the rates for surface seawater (Black Sea and Gulf Stream) with added H.S. Since the rates were the same for filtered (0.2 .m) and unfiltered waters, the increase in the rates appears to be abiotic and caused by dissolved solutes. To determine if this i

Ruthenium-106 is found at depths below the Chernobyl .Cs, indicating that .Ru is removed via particle scavenging processes, unlike the Cs isotopes which serve primarily as tracers of physical mixing. In 1988, more detailed measurements at depths
