The destination of the 95 expedition participants, led by the Alfred Wegener Institute, is the AWI Hausgarten, a [...] y situated between Svalbard and Greenland. There they will investigate how the ecosystems of the Arctic deep sea are reacting to changing environmental conditions as a result of rapid climate change. The [...] June, will focus on benthic and plankton communities in the open water and physical changes in the ocean.
