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.

New reference system for sea levels

As of June 3, 2019, sea levels in SMHI's observations, forecasts and warnings will be expressed in the Swedish national height system 2000 (Rikets Höjdsystem 2000, RH 2000) instead of relative the mean sea level. RH 2000 is Sweden's national reference system for heights and depths. The transition to RH 2000 is a step towards uniform reference systems at a national level and entails many advantages. For example, it facilitates analyses involving both land and sea and simplifies calculations of the under keel clearance for a boat or a ship.

Current climate information enables marine planning that is sustainable in the long term

Global climate change will affect the seas and the marine ecosystems for a long time to come. Current information about ongoing and future climate change will now be incorporated into Swedish marine planning. SMHI is leading a project in which various stakeholder groups will also be involved in work to create user-friendly information.
