Cruise report from KBV001 Poseidon week 45, 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 addition, due to problems with cranes on board, no CTD-measurements or zooplankton sampling could be carried out. In Skagerrak and Kattegat, nutrient conditions were normal for the season. In the investigated parts of the Baltic Proper concentrations of phosphate and silicate were higher than normal, while inorganic nitrogen showed normal values. Oxygen concentrations below 2 ml/l (hypoxia) were found at depth exceeding 60 metres in the Bornholm Basin as well as in the Hanö Bight.
