Studies on the Arctic pack-ice habitat and sympagic meiofauna : seasonal and regional variabilities
Sea ice is the main structural feature of polar seas. It plays an important role in energy transfer between the ocean and the atmosphere, but also serves as a natural habitat for a variety of organisms. Salt ions of the sea water are not included into the crystal structure of sea ice during freezing...

Sea ice is the main structural feature of polar seas. It plays an important role in energy transfer between the ocean and the atmosphere, but also serves as a natural habitat for a variety of organisms. Salt ions of the sea water are not included into the crystal structure of sea ice during freezing. These remain in the widely ramified system of brine channels within the ice. The brine channels are characterized by diameters of a few micro- to millimeters and provide a habitat for the so called sympagic (= ice associated) community. This association comprises bacteria, fungi, algae and protozoans, as well as metazoans. The investigated sympagic meiofauna of Artic pack ice mainly consists of copepods, nematodes, rotifers, turbellarians and nauplii. Late summer and winter pack ice of the central Arctic Ocean, the northern Fram Strait and the Storfjord (south of Spitsbergen) was sampled during three expeditions.
