Warning, (in Swedish), level 1, SwedenCruise reports from the marine monitoring
Reports from SMHI's regular marine monitoring programme. Data presented in the reports have been subject to preliminary quality control procedures only.Cruise report from KBV001 Poseidon week 42, 2011
Surface water temperatures as well as surface salinities were at normal levels for the season in the whole investigated area. Surface nutrient concentrations were mainly normal in most areas. Oxygen concentrations below 2 ml/l were found at depths exceeding 70-80 metres in the Baltic Proper, and at...Type: Reports, Cruise report from the marine monitoring, Oceanography

Cruise report from R/V DANA week 38-42, 2011
The survey was completed in co-operation with SLU (Swedish University of Agricultural Sciences) and within the international acoustic survey in the Bothnian Sea and Baltic Proper (BIAS) during weeks 38-42. The oxygen situation in the Baltic Proper is severe. Low oxygen concentrations (<2 ml/l) were...Type: Reports, Cruise report from the marine monitoring, Oceanography

Cruise report from KBV001 Poseidon week 37, 2011
The weather during the first part of the expedition was very rough with gale and heavy seas. At the visited stations in Kattegat, Skagerrak and the Sound nutrient concentrations showed normal values for the season. Lower silicate concentrations was found in south eastern and eastern Baltic proper. At...Type: Reports, Cruise report from the marine monitoring, Oceanography

Cruise report from R/V Franklin week 14, 2011
Surface water temperatures were normal in the Skagerrak and Kattegat but somewhat below normal in the Baltic. Spring bloom was over in the central parts of Skagerrak, in Kattegat and in the Arkona Basin and surface nutrient concentrations were low. In the reminder of the Baltic bloom was in its infancy...Type: Reports, Cruise report from the marine monitoring, Oceanography

Cruise report from R/V Franklin week 10, 2011
Surface water temperatures were below normal in the whole area. Surface nutrient concentrations were normal at most stations but above normal silicate and nitrate concentrations were recorded in the central parts of Skagerrak and in the Arkona Basin. The bottom water of the Arkona Basin was well oxygenated...Type: Reports, Cruise report from the marine monitoring, Oceanography

Cruise report from R/V Argos week 2, 2011
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...Type: Reports, Cruise report from the marine monitoring, Oceanography

Cruise report from R/V Argos week 48-49, 2010
Surface water temperatures, from the Skagerrak to Gulf of Bothnia, were lower than normal. Above normal phosphate and silicate concentrations were recorded in the surface waters of the Western Gotland Basin, in the Bornholm Basin and in the Gulf of Bothnia. Oxygen concentrations below 2 ml/l were observed...Type: Reports, Cruise report from the marine monitoring, Oceanography

Cruise report from R/V Argos week 38-39 and 41-43, 2010
The oxygen situation in the deep water of the Baltic Proper continues to be serious. About one sixth (~17%) of the bottom area in the Baltic Proper are affected by anoxia (oxygen free, with toxic hydrogen sulphide present) corresponding to ~10% of the water volume. Acute oxygen deficiency, with concentrations...Type: Reports, Cruise report from the marine monitoring, Oceanography
