PRESS RELEASE

The sea-ice is getting thinner - A closer look at the climate and ecosystem of the Arctic Ocean

Bremerhaven, September 13, 2007. Large areas of the Arctic sea-ice are only one metre thick this year, equating to an approximate 50 percent thinning as compared to the year 2001. These are the initial results from the latest Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association lead expedition to the North Polar Sea.  50 scientists have been on board the Research Vessel Polarstern for two and a half months, their main aim; to carry out research on the sea-ice areas in the central Arctic. Amongst other things, they have found out that not only the ocean currents are changing, but community structures in the Arctic are also altering. Autonomous measuring-buoys have been placed out, and they will contribute valuable data, also after the expedition is finished, to the study of the environmental changes occurring in this region.
