This pedagogic 11 minutes video "Urban Water Vision" explains the necessity to downscale climate model output in order to adapt to future intense rainfall over urbanized areas.

In Skagerrak and Kattegat, nutrient conditions were normal for the season, with the exception of silicate, that in Kattegat showed elevated concentrations. In the Sound, both phosphate and silicate levels were much higher than normal. In the Baltic Proper concentrations of phosphate and silicate …

Oxygen conditions in the south eastern Baltic have improved thanks to an inflow of oxygen-rich water from the North Sea during November/December 2011. This inflow has also caused the concentrations of phosphate and silicate to increase in the surface waters, which could cause excessive algal blooms …

The phytoplankton diversity was very low in the Skagerrak and the Kattegat and cryptomonads were the most numerous. The integrated (0-20m) chlorophyll a concentrations were within normal in the Skagerrak and slightly below normal in the Kattegat. In the Southern Baltic a declining diatom bloom was …

In the Skagerrak and Kattegat, the situation was normal for the season. In the Sound, phosphate and silicate concentrations were much higher than normal. In the Baltic Proper the spring bloom was underway, but the concentrations of phosphate and silicate were still much higher than normal. The …

The diatom spring bloom had ceased in The Kattegatt and Skagerrak areas. The total cell concentrations were very low and dominated by cryptomonads and ciliates. The integrated (0-20 meters) chlorophyll a concentrations were lower than normal in the Kattegatt and Skagerrak areas. The total cell …

In Skagerrak and Kattegat the spring bloom was over and the amount of nutrients was low, which is normal for the season. In the Baltic Proper winter conditions prevailed. The concentrations of nitrite+nitrate were normal while the amount of phosphate still were elevated at all stations and much …

SMHI hydrological research unit is involved in many national and international projects in hydrological modeling. Here below, on-going and finished projects are listed alphabetically with a short summary.

An extensive spring bloom was observed at all phytoplankton stations in the Kattegat and Skagerrak areas. The diatom Skeletonema marinoi dominated the samples. The general species composition was more or less the same in the whole area, many diatom species in high cell numbers and a few …

In Skagerrak and the north Kattegat the spring bloom was ongoing and the amount of nutrients was low. The southern parts of the Kattegat and the Sound were influenced by outflowing winter water from the Baltic with high concentrations of nutrients. In the Baltic Proper winter conditions prevailed. …
