Bremerhaven / Tromsø (dpa) - The scientists of the one-year Arctic expedition "Mosaic" starting on Friday have great expectations of their own research trip. "I'm sure that will enable us to achieve a breakthrough in climate research," says expedition leader Markus Rex.
For one year, the research vessel "Polarstern" of the Alfred Wegener Institute in Bremerhaven will drift with the sea ice through the central Arctic, docked to a huge ice floe.
The scientists make extensive measurements and experiments during the voyage in the winter Arctic Ocean, which is normally only accessible in summer. "We do that because the Arctic is the epicenter of global climate change," says Rex. Nowhere is global warming advancing as fast as there. "At the same time, the Arctic is also the region of our planet where the climate system is at its worst."
