Summary
China's polar research vessel Xuelong has completed 12 ice station surveys in the Arctic Ocean, setting a new single-ship record for Arctic expeditions . The mission, part of China's 16th Arctic Ocean expedition organized by the Ministry of Natural Resources, achieved unprecedented success by conducting all surveys in high-latitude ice regions north of 82 degrees North . Researchers deployed over 30 ice-based buoys and collected a substantial ice cube measuring 1.3 meters in thickness and 1.2 meters in both length and width, weighing approximately one ton . The expedition team spent six hours extracting the ice sample using ice core drills and chain saws, which will be analyzed to understand sea ice mechanical properties for designing next-generation polar vessels . A key innovation was the deployment of an ecological unmanned ice station, the first application of this technology in the Arctic, enabling scientists to study how sub-ice organisms survive polar night and greet the first sunlight of polar day .
Key Points
- The Xuelong completed 12 ice station operations, surpassing all previous single-ship Arctic expeditions
- All stations were located north of 82 degrees North, with the final site at 83 degrees 50 minutes North in the central Arctic Ocean
- A 1-ton ice block (1.3m thick, 1.2m x 1.2m) was extracted over six hours for sea ice mechanics research
- Over 30 ice-based buoys were deployed to create an unattended Arctic Ocean observation network
- The ecological unmanned ice station achieved its first application demonstration in the Arctic
Why It Matters
The data gathered will provide crucial support for developing next-generation polar vessels capable of navigating increasingly rapid Arctic sea ice changes . The establishment of a continuous monitoring network enables scientists to track climate and oceanic transformations in the Arctic in real-time, offering invaluable baseline data for global climate models and international environmental policy discussions .
