speed of several millimetres to centimetres per year (plate tectonics). So-called mid-oceanic ridges run through the oceans. In these zones magma rises from the Earth’s interior to the surface, cools down there [...] magma again. A region in which new seafloor continuously forms is, for instance, Gakkel Ridge in the Arctic. This is a submarine mountain range whose northern foothills extend from the northeast tip of Greenland

That means, the ocean warms the climate in Spitsbergen, which is why in summer the [...] Spitzbergen has risen by 1.3 °C. A warming of the Arctic, which becomes apparent especially in winter. The main climate influence in Ny-Ålesund is the Arctic Ozean.

We combine long term observations from ground stations and innovative measurements [...] improving the representation of polar processes in regional to global scale climate models. We run the Arctic research station AWIPEV on Svalbard and the meteorological and atmospheric observatory at the Antarctic
