Research vessel provides comprehensive assessment of the changing Central Arctic Ocean

The Polarstern expedition, ArcWatch-2, has returned from a four-month Arctic mission, Phys.org reports, The research vessel is already providing critical data on sea ice, ocean circulation, and ecosystem dynamics so that they better understand Arctic changes within the global climate system.

• Prof. Benjamin Rabe highlighted the unusually sparse ice cover compared to long-term averages, indicating a persistent trend similar to the previous year’s findings. The analysis will explore connections between ice conditions, atmospheric influences, and ocean circulation patterns.
• The expedition also focused on marine chemistry, collecting more than 20,000 liters of water samples to assess trace metals and pollutants, enhancing the understanding of anthropogenic impacts in the Arctic. Dr. Walter Geibert noted that this research will help track historical pollution trends and gauge the effects of environmental legislation.
• Biodiversity findings were significant, with the discovery of abundant marine life, including luminescent sardines, indicating a richer ecosystem than previously recognized. The data collected will support the Central Arctic Ocean Fisheries Agreement, laying groundwork for sustainable fishing practices in the region.
