Cruise report from KBV001 Poseidon week 42, 2012

Type: Report
Author: Lars Andersson


A new agreement with the Swedish Coastguard meant that only the Swedish west coast and south western Baltic Proper (Arkona and Bornholm Basins) were sampled. In Skagerrak and Kattegat, nutrient conditions were normal for the season. In the south western parts of the Baltic Proper concentrations of phosphate and silicate were still high, while inorganic nitrogen showed normal values. Plankton activity was principally low in all areas. Oxygen concentrations below 2 ml/l (hypoxia) were found in the bottom water in the Sound and at depth exceeding 60 metres in the Bornholm Basin as well as in the Hanö Bight.
