After 183 days in the Antarctic, the research vessel Polarstern returned to its home port today, 15 May. She was welcomed in Bremerhaven in the presence of Federal Research Minister Dorothee [...] and Marine Research (AWI), Hajo Eicken. From its voyage, the Polarstern is bringing back important findings on the causes of the recent sea ice retreat in the Antarctic and its repercussions.
