In this report we present budgets of oxygen and phosphorus for the deeper layers of the Baltic proper. The budgets give calculations of sedimentation, erosion and horizontal and vertical transports based on model simulations. The fluxes of oxygen and phosphorus as well as trends in contents have …

New reports from SMHI provide geographically detailed information about climate trends in Sweden, depending on future levels of greenhouse gases. The climate analyses can be used for community planning and highlights increasing risks as the climate changes.

The Baltic Sea is optically a multi-componental water and has exceedingly high levels of colored dissolved organic matter (CDOM, also referred as yellow matter, gilvin or gelbstoff). CDOM is a complex mixture of chemical bonds originating from the decay of photosynthetically produced organic …

The stratification in the open sea areas of Skagerrak was very weak. In the Kattegat and the Baltic Proper sea surface temperature values was slightly above normal. Surface nutrients showed mainly values typical for the season, except for silicate which had concentrations well above normal in the …

HazardSupport is a project 2015-2020 where SMHI and SEI (Stockholm Environment Institute) collaborate with the aim of developing a risk-based decision support for adaptation to future natural hazards. The project is funded by the Swedish Civil Contingencies Agency, MSB.

The overall aim of the project is to improve observations of the status of Europe's coastal waters by linking existing observation systems and developing new methods. The EU Marine Directive is one of the reasons for the project starting.

The phytoplankton community in the Skagerrak and the Kattegat was dominated by a small coccolithophore, Emiliania huxleyi, and a diatom, Pseudo-nitzschia spp. The potentially harmfull naked dinoflagellates Karenia
mikimotoi and Karlodinium veneficum were common and particularly at Släggö. The …

The surface water in Skagerrak and Kattegat was somewhat cooler, around 11°C, than the surface water in the Baltic Proper where there was about 13°C. Inorganic nitrogen (NO2+NO3) in surface waters were close to the detection limit in all regions. The concentrations of phosphate were low …
