Cruise report from R/V Argos week 2, 2011

Summary

Surface water temperatures were low in the Kattegat but normal in the remainder of the area. Surface nutrient concentrations were normal in most areas, except for phosphate, which was higher than normal in the Bornholm Basin, and silicate, that also was above normal in the Bornholm Basin and in the western and northern Gotland Basins. The bottom water of the Arkona Basin was well oxygenated, while elsewhere in the Baltic Proper, oxygen concentrations below 2 ml/l were found at depths exceeding 50-70 metres. Hydrogen sulphide was found in the eastern -, northern – and western Gotland Basins.
