In the Northern Hemisphere, the ocean gradually freezes over in the course of the long Polar [...] near the end of winter. At this point, the Arctic Ocean is completely covered in ice from between the coasts of Canada, Alaska and Siberia to the eastern coast of Greenland. When the sun returns, the ice [...] the formation and melting of sea ice affect the atmosphere and the ocean, and with them, the climate, in a variety of ways. The ice reflects the majority of incoming sunlight back into space. In contrast

studies in biology at the University of Bremen and then returned to the AWI and especially to the labs. Here, the supervision of our microalgal stock culture collection, the realization of lab experiments on [...] content are also part of the spectrum of my tasks in the group, besides the preparation of expeditions and ordering logistics. "What will happen tomorrow?" is an important question for me, not just regarding [...] faster than the global average. The influx of warm Atlantic water and the rapid melting of glaciers, releasing sediments and freshwater, make Svalbard a unique place to study the effects of climate change

Contact: Alexander [...] and health in the high latitudes, as well as proxy development and proxy data synthesis, along with the analysis of global interactions, are central research interests of the group. The goal is to achieve

And the eyes of muskoxen work like a combination of snow goggles and night vision gear. Yet the future of all these survivors is uncertain; over the past few decades, the living conditions in the Arctic [...] comes to surviving in the Arctic, it’s a whole new ball game. Arctic sea ice at sunrise (Photo: Stefan Hendricks) The Arctic Ocean Unlike at the southern tip of the planet, in the High North there is no [...] which form on the ice in the summer and freeze over in the autumn. In many regions of the Arctic, the melting sea ice will likely result in higher productivity among the ice algae in the short term. Yet

exchange, the rise and the lowering of the cage needs sufficient stops to prevent barotrauma of the fish. The sea bass can tolerate temperatures in the North Sea, but the average temperature of 10 ° C in [...] flow velocities of 5-10 cm s -1 for optimal nutrient and CO 2 exchange on the surface of the thalli, as well as for the reduction of growth of epiphyts. In strong currents, the thalli of macroalgae become [...] materials. Cod is one of the species with the highest rate of the escapees, which can have a negative impact on the wild population by cross-breeding. The extreme temperature tolerance range of -1 ° C to 23 °

The Kerguelen Plateau rises up 2000 m above the surrounding seafloor and hence forms an obstacle for the flow of the Antarctic [...] region in the southern Indian Ocean the complex topography of the Kerguelen Plateau, one of the world’s largest Large Igneous Provinces, has a strong influence on pathways of water masses within the Antarctic [...] information on the Cretaceous and Tertiary development of the AABW and its influence on the path of the Antarctic Circumpolar Current. This in turn will allow conclusions on the development of the East Antarctic
