Cruise reports from the marine monitoring

The temperature of the surface water remained above normal, but not as pronounced as during the November expedition. Surface nutrients showed, for the season almost normal values, except silicate in the Baltic Proper.

In the Bornholm Basin and Hanö Bight acute hypoxia (<2 ml / l) occurred …

The water temperature in the surface layer was still above normal in all areas. Surface nutrients showed, for the season, almost normal values, except for silicate in the Baltic Proper. At the station BY1 in the Arkona Basin all nutrients showed increased values.

In the Bornholm Basin and Hanö …

Water temperature in the surface layer was slightly above normal in the whole investigated area. Nutrients in the surface layer showed normal concentrations, except for elevated silicate concentrations in the western and eastern Gotland basin. In the western part of Skagerrak a thin layer …

The water temperature in the surface layer was above normal in Skagerrak and the Baltic Proper. The thermocline in Skagerrak was found at 75-100 meters which is significantly deeper than normal. Nutrients in the surface layer showed normal concentrations except for silicate that in the Western and …

Surface water temperatures were above normal in all investigated areas. Nutrients in the surface layer showed concentrations normal for the season in all sea areas.

Oxygen situation in the bottom water of the Arkona Basin, Bornholm Basin and Hanö Bight were bad, below acute hypoxia (< 2 ml/l). In …

Surface water temperatures were above normal in most of the investigated areas, with the exception of the Western Baltic Proper, where temperatures were below normal. Nutrients in the surface layer showed concentrations normal for the season in all areas.

The oxygen situation in the Hanö Bight and …

Surface water temperatures were above normal in most of the investigated areas, with the exception for the Northern and Central Baltic Proper, where temperatures were typical for the season. Nutrients in the surface layer showed concentrations normal for the season in all areas.

Oxygen situation …

In the Skagerrak and Kattegat, surface nutrient was normal for the season in most of the investigated places. In the Baltic Proper, except the Arkona Basin, the concentrations of phosphate and silicate were higher than normal.

The oxygen concentrations in the bottom water in Hanö Bight and the …

In the Skagerrak and Kattegat, surface nutrient was normal for the season in most of the investigated places. In the Baltic Proper, except the Arkona Basin, the concentrations of phosphate and silicate were higher than normal. The oxygen concentrations in the bottom water in the Hanö Bight and …

In the Skagerrak and Kattegat, surface salinity was lower than normal, which indicates an influence of outflowing Baltic water. In the Baltic Proper the concentrations of phosphate and silicate were elevated in the Western Gotland Basin. The oxygen concentrations in the bottom water in Hanö …
