title: Features of the Oxygen and Sulfide Vertical Distribution in the Black Sea Based on the Expedition Data Obtained by Marine Hydrophysical Institute in 1995–2015
abstract: Discussed are the features of the oxygen and sulfide vertical distribution resulted from the expedition data obtained by Marine Hydrophysical Institute in the northern part of the Black Sea (within the economic zone of Russia) in 1995-2015. In course of the last 20 years, the upper boundary of the sulfide zone in this area, defined by the sulfide isoline 3 M, did not change its position in the scale of relative density and is located on t = 16.10-16.15 kg/m 3 . Closer to the northwest shelf (in
