Cruise reports from the marine monitoring

In large parts of the deep water in the Baltic Proper the oxygen concentration was close to zero. Anoxic conditions, when hydrogen sulphide can form, were found in both the Western and the Eastern Gotland Basin from 80-90 meters depth. In the Bornholm Basin the oxygen concentration went down to 0.4 …

In large parts of the Baltic Proper, the oxygen concentration in the deep water was close to zero. Anoxic conditions, when hydrogen sulphide can form, were found at all stations sampled in the Western and Eastern Gotland Basin. The depths where hydrogen sulphide were first detected at the visited …

The cruise, which is part of the Swedish national marine monitoring programme visited stations in the Skagerrak, the Kattegat, the Sound and the Baltic Proper. In the Kattegat and the Sound the winter pool of nutrients were mapped.

As usual had large parts of the deep water in the Baltic Proper …

The February cruise, which is part of the Swedish national marine monitoring program, covered the Skagerrak, the Kattegat, the Sound and the Baltic Proper. In the Baltic Proper winter mapping of nutrients was performed.

In the northern and westerns parts of the Baltic Proper there was hydrogen …

The expedition was included within SLU:s International Bottom Trawl Survey and covered the Skagerrak and the Kattegat.

Mapping of winter nutrient conditions was performed in the Skagerrak and 14 stations with complete hydrography were sampled. In the Kattegat area 12 stations were sampled with ctd …

Initial problems with our CTD caused some delays since a thorough troubleshooting had to be performed. The problem turned out to be the computer and probably a malfunctioning serial port. The computer could temporarily be replaced until we reached Lysekil, there a permanent replacement computer was …

The expedition was included within SLU:s International Bottom Trawl Survey and covered the Skagerrak and the Kattegat. Also during the expedition, SMHIs standard frequent stations were visited. In Skagerrak 9 stations with complete hydrography were sampled in the Skagerrak and 12 stations in the …

The cruise, which is part of the Swedish pelagic monitoring program, visited the Sound, the Baltic Proper and parts of the Kattegat. In the Kattegat, Anholt E represents the entire sea area since neither N14 nor Fladen were sampled. This is otherwise done during a regular monitoring cruise. Due to …

The warm and sunny weather in May, in combination with calm winds, had warmed the surface water, and the surface water temperature was above normal at all visited stations. High phytoplankton activity was found mainly at the stations in the Baltic Proper, indicating ongoing spring bloom. Large …

The spring bloom was ongoing in almost the whole area and large peaks in fluorescence was measured with the CTD.

The deep water in large parts of the Baltic Proper has oxygen concentrations near zero. Completely oxygen free areas, when toxic hydrogen sulphide is formed, were measured in the …
