How is the Arctic Ocean changing?
Date:6/14/2011

water and on the bottom of the deep sea react to the progressive warming of the nordic seas. In this context they will investigate the critical physiological and ecological limits of selected species. This makes it possible to draw conclusions as to whether organisms are able to tolerate increasing temperatures, for example, or whether they withdraw from the region as warming progresses. With the help of a remotely operated vehicle (ROV) chartered from the IFM-GEOMAR marine research institute in Kiel experiments will also be conducted on the floor of the deep sea. Another underwater vehicle (AUV), which has a length of around five metres, is also unmanned, but operates autonomously, will be used at water depths down to approx. 600 metres as well as just under the Arctic sea ice. By means of measuring instruments that were newly developed at the Alfred Wegener Institute, it records, among other things, the distribution of unicellular algae and the carbon dioxide concentration near the water surface. Furthermore, the scientists plan to take seafloor samples from a marine area in which fishery echosounders recently detected numerous gas flares. They indicate that probably enormous quantities of methane, a greenhouse gas with certain relevance for the climate, are released from the seafloor at water depths of around 400 metres west of Svalbard.

As of the beginning of August, the research vessel Polarstern will then set course for the Arctic Ocean. The focus will be on physical, biological and chemical changes in the central Arctic. The reduction of sea ice and the variability of ocean circulation and its heat and fresh water budgets are tightly linked with changes in the gas exchange as well as with biogeochemical and ecosystem processes in the sea ice and in the entire water column. To understand these interrelations better, the members of the expedition will take water and ice samples from the shallow Eurasian shelf seas all the way to the deep Canadian Basi
