Research group The North Atlantic and Arctic Oceans
In the North Atlantic, a mighty current system conveys, via the Gulf Stream and North Atlantic Current, warm surface waters to northerly subpolar areas where deep water is formed. This current system, which is an important link in the global ocean circulation connecting the Atlantic and Pacific Oceans, also carries warm Atlantic water into the Arctic Ocean.
The North Atlantic–Arctic ocean circulation is driven by a complex interplay between the atmosphere and the ocean, which is influenced by regional processes as well as conditions remotely in the Southern and Pacific Oceans.
Our research aims to understand the mechanisms of the ocean circulation in the North Atlantic and Arctic Oceans, specifically the dynamics steering warm Atlantic Water into the Nordic Seas and the Arctic. Overarching questions concern the current systems' time variability, stability and impact on Arctic sea ice and marine glaciers.
In our research, we use observations from satellites and Arctic expeditions together with theoretical and numerical models. Research themes encompass the interplay between the large-scale circulation and bottom topography and small-scale eddies, and how Atlantic Water drives subsurface melt on glaciers in Greenlandic fjords. We also contribute to develop numerical models to examine the ocean–glacier interactions that control the subsurface melt processes.
