The CIL waters are identified by core temperatures of about 6.5 °C in the Bosphorus exit region and 7.0–7.2 °C in the southeastern part of the Black Sea. The Mediterranean underflow, crossing the the southwestern Black Sea shelf region, is s

Factors Affecting the Oxygen Isotopic Composition of the Black Sea,orus. However, the oxygen isotopic composition of the upper layer continues to change slowly over a period of 1000 years, the time needed for the lower portion of the Black Sea to approach a steady state isotopic composition. The model further predicts that the oxygen isotopic composition is relativ

Geochemical and Structural Aspects of the Pycnocline in the Black Sea (R/V KNORR 134-8 LEG 1, 1988) the transmissometer peaks. These observations could be explained by mobilization of Mn from shallow coastal sediments, a process which may greatly be enhanced by internal waves warping the pycnocline near the coast and operating a “manganese pump”. Macroflocs, present at concentrations between 0.8

The inhibition of Mn(IV) reduction by oxygen could largely be accounted for by the activities of Mn(II) oxidizing bacteria. These experi

These zones in the western and central basins are (1) the oxic [0 – 65 m], (2) the anoxic and non-sulfidic [65 – 100 m] and (3) the sulfidic [> 100 m]..Thiosulfate and sulfite were below our minimum detectable limit (MDL) of 50 nM using CSSWV.
