Marine environment

The sea is often in focus as a resource for society and its people, for recreation and for transportation. A sustainable environment and climate development are prerequisites for a sustainable use of ocean and its resources. SMHI provides the individual, government, researchers and the international community with data, forecasts and scenarios, and current information.

Summer school increases knowledge of the Baltic Sea Region's future climate

Starting next week, the BONUS research programme will host a summer school, which will bring around 30 young researchers together for an interdisciplinary exchange, which will focus on the Baltic Sea. Researcher Helén Andersson from the Swedish Meteorological and Hydrological Institute (SMHI) will participate, and will share her knowledge about the Baltic Sea's future climate.

The Baltic Sea Region’s climate is presented in a new book

The Baltic Sea Region will become significantly warmer in the future. There is now a new compilation which describes the Baltic Sea Region’s climate, how it has changed to date and expected developments until the year 2100. It involves an increase of the sea level, coastal erosion and effects on urban areas.

BalticAPP is set to collect information about the environmental state of the Baltic Sea

An upcoming mobile app will give the general public vital information about the state of the environment in the Baltic Sea. Thanks to this app, anyone will be in a position to assess the state of the environment at a given location. The three-year BONUS project BalticAPP has the task of developing the tool.


My Ocean

Ocean Monitoring in Europe standardised in the MyOcean mega project. SMHI and more than 60 other institutes is working on EU MyOcean project. The monitoring of all oceans from the Black Sea to the Barents Sea is to be combined and downscaled which will improve oceanographic forecasts.


ECOSUPPORT (Advanced tool for scenarios of the Baltic ECOsystem to SUPPORT decision making) is a BONUS funded project to address the urgent need for policy relevant information on the combined future impacts of climate change and industrial and agricultural practices in the Baltic Sea catchment on the Baltic Sea ecosystem.

Oceanographic research

The oceanographic research group at SMHI have expertise in a wide range of ocean science fields such as numerical modelling, remote sensing, marine biology and marine observations.


Climate indicators

SMHI has developed a number of "climate indicators" that can be used to follow the climate change in Sweden. The climate indicators show deviations in temperature, precipitation, geostrofical wind and sea level.

Environmental Fact sheets

SMHI has developed a range of fact sheets describing every year the environmental status. These are used both nationally and internationally, for example within HELCOM cooperation. The fact sheets describe on a yearly basis the development of salinity, stratification, oxygen, water exchange, river run-off, cyanobacteria blooms and the spatial distribution of winter nutrients.



Reports from SMHI's offshore sampling programme, which describe the situation in our surrounding seas.

Sea observations

Access to data - sea level, temperature, salinity, forcasts, wave height and currents.

Weather and oceanographic data from icebreakers

Weather and oceanographic data are now transferred in real-time from the icebreakers Oden, Frej and Atle via satellites. The icebreakers operate primarily in the Gulf of Bothnia but are available for the whole Baltic Sea region if needed. Oden also operates in Arctic and Antarctic waters during certain years.



Learn more about the ocean - sea ice, waves, currents, sea level, algal blooms and other physical properties of sea water.


Marine environmental data

Extract marine physical, chemical and biological data from the Swedish environmental monitoring.

Swedish water archive (SVAR)

Here your can find information about Swedish water bodies.


SeaDataNet is a co-operation between the European oceanographic data centres, which makes data available from one single web site.

EMODnet - European data

EMODNET Chemistry 2 is built on EMODNET Chemistry pilot components of the EU's maritime policy, to deliver a marine observation infrastructure that offers the most effective support to the marine and maritime economy whilst supporting environmental protection needs, launched by the Directorate-General for Maritime Affairs and Fisheries (DG MARE).

BALTEX (The Baltic Sea Experiment)

BALTEX is a part of the World Meteorological Organization. The GEWEX project studies the flows of eg. carbone and nutrients in the Baltic sea region. SMHI provides the project with oceanographical and hydrological data.

Environment Climate Data Sweden

Environment Climate Data Sweden, ECDS, is a Swedish service facilitating the searching, publication and long-term accessibility of data for research in the fields of environment and climate.


Dispersion calculations and risk assessments

SMHI calculates how pollutants and other emissions disperse into the air and water under different conditions.

Tracking of pollutants in the sea

To minimise the damage on the environment, it is important to quickly develop a forecast regarding how the oil is dispersing and where it is heading.

HOME Water-action planning for lakes, watercourses and coastal waters

With the web service HOME Water, it is possible to carry out a cost-effective action planning in accordance with EU’s framework directive for water for lakes, watercourses and coastal waters.

Measurements in the air and water

SMHI carries out qualified measurements of the air and water which form the basis of economic and environmentally strategic decisions. The investigations concern physical and/or chemical conditions.
