China Completes First Manned Dive Under Arctic Ice

China’s 15th Arctic expedition included over ten dives collecting 183 biological samples to improve understanding of Arctic ecosystems and climate impacts, officials said.

  • On September 26, Xue Long 2, icebreaker, returned to Shanghai, China, concluding China's 15th Arctic Ocean Scientific Expedition, the country's largest and most comprehensive Arctic mission to date.
  • China's Ministry of Natural Resources organized the summer expedition with four research vessels to fill observation-data gaps in high-latitude Arctic areas and improve marine environment forecasting.
  • Over more than ten dives, Jiaolong, manned submersible, collected 183 biological samples and executed the world's first coordinated crewed and uncrewed submersible operation in the polar region.
  • Researchers found preliminary findings revealed significant spatial variations in benthic organisms, and higher-quality samples from the National Deep Sea Centre in Qingdao will support global climate change efforts.
  • Amid rising Arctic competition, the U.S. Coast Guard monitored Chinese vessels entering the Extended Continental Shelf as China declared itself a `near-Arctic state` and dispatched five research vessels.
