DTU Space uses sea level measurements to devise models for variations in sea levels. These variations are due to the tide as well as changes in the position of the ocean currents. It is also possible to identify ocean currents in the Pacific caused by El-Niño.
DTU Space also uses the satellite measurements of the Earth’s gravity field to devise models of the global ocean currents, which to a large extent control the entire climate system on Earth. The main purpose is to devise better ocean models, which will lead to better predictors of flooding for the benefit of shipping as well as better climate models. DTU Space contributes towards the European satellite mission GOCE by developing methods for using the mission’s gravity field measurements to map the Earth’s ocean currents.
