Chemical oceanography during POLARSTERN cruise ARK-IX/4

Marine chemistry data (dissolved oxygen and dissolved inorganic nutrients) were collected from 10 august 1993 to 24 September 1993, during ARK IX/4cruise, along six sections stretching from the continental shelves of the Barents and Laptev Seas, over the shelf break and into the deep Eastern Nansen...

Description
Summary:Marine chemistry data (dissolved oxygen and dissolved inorganic nutrients) were collected from 10 august 1993 to 24 September 1993, during ARK IX/4cruise, along six sections stretching from the continental shelves of the Barents and Laptev Seas, over the shelf break and into the deep Eastern Nansen and Amundsen Basins. These investigations are a direct continuation of "SEAS" project in the Barents Sea (ARKVIII/2, 1991). The dataset includes discrete samples, at different depths, of 63 stations.Sampling of chemical measurements was carried out in parallel to physical-oceanography sampling and phytoplankton work using Rosette-water sampler mounted on a CTD (Neil Brown, Mark III). Discrete water samples for dissolved oxygen (DO) and dissolved inorganic nutrients (nitrate, nitrite, phosphate and silicate) were collected and analyzed directly on board of R/V Polarstern within a few hours after sampling. Dissolved inorganic nutrients (NO3+NO2, SiO4, PO4) have been measured by means of a Chemlab Continuous FloW Analyser according to the standard methods reported by Grassof 1983. Dissolved oxygen was analyzed by the Winkler method, according to Grasshoff 1983, as well.
