Ocean currents and water temperatures<\/h1><\/div>

The sea is home to an incredible number of animal species, it provides us with food and energy, serves as a transport route and has a major impact on the climate of the globe. Two important factors that influence what happens in the ocean are ocean currents and temperature.<\/p><\/div>[vc_column_text]<\/p>\n

We use several methods to research the conditions in the sea. Measurements and models are used to study the transport of heat, salt, nutrients, gases, and various types of pollution. The Nansen Center is responsible for the northernmost part of the marine services for the EU’s Earth observation program Copernicus. Through our data assimilation and ocean modelling services, we contribute to the safest possible information about the state of the ocean right now, and in the near future, regarding ocean circulation, waves, and sea ice.<\/p>\n

In the sea, eddies occur, which are currents that rotate and reach deep into the water masses. Using models and satellite data, we investigate how the eddies affect marine ecosystems and the interaction between the air and the sea. The results are important in climate research. Another way to investigate the conditions below the sea surface is to use so-called Argo buoys, a measuring instrument that moves up and down in the water column. Data from the buoys is used to improve reconstructions and forecasts about the state of the ocean and ecosystem. We are also developing new methods for information acquisition via satellite. Precise information about ocean currents increases safety for marine traffic and other activities along the coast.<\/p>\n
