Very high surface phosphate concentrations were measured in the Baltic Proper. Silicate concentrations were also enhanced there, while levels of nitrogen compounds were normal. Nutrient concentrations in the Skagerrak-Kattegat area were normal or almost normal. The spring bloom in the …

HIROMB BS01 (High Resolution Operational Model for the Baltic Sea) is an oceanographic forecasting model that describes the state of the sea for a number of physical parameters.

There are two options – download oceanographic analysis data via an interface or subscribe to a feed of oceanographic …

Oceanographic observation data comes from SMHI’s measurement stations along the coast and at sea. A station can deliver data for several oceanographic parameters.
Use the  to obtain all data for a specific parameter for three different time periods:

You can subscribe to real-time data and receive continuous updates via atom feeds. Some prior knowledge is needed in order to use these services for machine to machine downloads.

Conditions for data

Surface water temperatures were normal for the season in all investigated areas. All nutrients in the surface layer were low and had increased since the last observation, which is normal for the season. The oxygen conditions in the Kattegat bottom water were relative good. The oxygen condition …

There was no increased nutrient concentrations recorded in Skagerak or Kattegatt and the spring bloom had not began. The oxygen condition in the bottom water of Skagerrak was good and no station recorded a saturation below 90%. In the bottom water of Kattegatt the lowest recorded oxygen …

Very high surface phosphate concentrations were measured in the Baltic Proper. Silicate showed enhanced concentrations there though nitrogen compounds were normal. Nutrient concentrations in the Skagerrak and Kattegat were normal or almost normal. In the Baltic Proper oxygen concentrations were …

Surface water temperatures in the Skagerrak and the Kattegat were above normal. High nutrient concentrations were found in the surface waters outside of Gullmarfjord, due to recent heavy rain. Concentrations in the southeastern Skagerrak were also high, due to influence from southern North Sea. An …

Western Gotland Basin: Oxygen conditions at the bottom were bad. Concentrations below 2 ml/l were found deeper than 50 to 70 metres. Hydrogen sulphide was recorded from depth of 80 meters in general, but locally already from 70 meters. Eastern Gotland Basin (western part): Oxygen levels below 2 …
