Hausgarten Expedition ends
On Sunday afternoon, the research icebreaker Polarstern returned from its roughly one month-long Arctic expedition to the Fram Strait. In the so-called AWI Hausgarten the approximately 50 scientific expedition participants continued their more than 20 years of long-term research on the effects of global climate change on the Arctic ecosystem. Polarstern will spend the coming months in the shipyard for extensive maintenance work.
