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.

Climate change increases eutrophication in the Baltic Sea

Model projections of the Baltic Sea show that changes will occur in the marine environment in a future climate. Nutrient load reductions to the Baltic Sea are of even higher importance in a warmer climate. A modeling tool has been developed to support decision making.

Baltic Sea environment visualized during EU Commission forum

What causes eutrophication in the Baltic Sea? What are the future scenarios for the ocean? Ocean environment issues will be illustrated in a visualization dome theatre during EU Commission forum in Gdansk, October 24-26th.

Summer blooms in the Baltic Sea

This summer, blooms of cyanobacteria were observed for more than two months period, from 29 June to 5 September. During 30 days from the 7 July, extensive blooms were seen, but the most massive accumulations stayed away this year. The Gulf of Bothnia, which usually blooms in August, also had an unusually prolonged bloom.

Conferences and seminars

Conference on marine investigation technology 2012 (MUT-12)

SMHI is this spring hosting MUT-12 which is a conference about marine investigation technology. The conference is organized at SMHI in Norrköping, 8-9 March 2012, and will, among other things, be about in-situ monitoring of algal blooms and several new ways to measure the sea.

RESEARCH

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. Ocean monitoring in Europe standardised in the MyOcean mega-project

ECOSUPPORT

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.

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.

Environmental Indicators

SMHI has developed a range of indicators describing every year the environmental status. These are used both nationally and internationally, for example within HELCOM cooperation. The indicators 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.

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.
