Hydrochemical structure of the Black sea along the Standard Section from Gelendzhic to the centre of the sea (November, 1977)

Results on dissolved oxygen, hydrogen sulfide, nitrate, nitrite, amonium, m anganese and methane in the Black sea water are presented for the Standard Section from Gelendzhic to the centre of the sea. The determinations were c arried out onboard R/V "Akvanavt" in November 1997. Sampling and hydrophysi cal testing (density, temperature, transparency) were performed with help o f Sea Bird probe, which had twelve 5 L plastic Niskin water samplers. All d eterminations were performed down to the maximum depths (more 2000 m).
