Core Viewpoint - The "Jiaolong" manned submersible successfully completed over 10 manned deep dives in the Arctic, marking China's first manned deep dive in Arctic ice areas, showcasing the enhancement of China's deep-sea entry and exploration capabilities [1][3]. Group 1 - The "Jiaolong" submersible has undergone domestic upgrades and has officially entered polar operations after sea trials in the South China Sea [3]. - The expedition, part of the China Ocean 92 voyage, was conducted from July 15 to September 8, 2025, with the support of the icebreaker "Snow Dragon 2" [3]. - The operation included manned dives, ROV investigations, and CTD water sampling in the Arctic sea area [3]. Group 2 - Valuable scientific insights were gained, including significant differences in benthic organism density, biodiversity, and individual size across tens to hundreds of kilometers, likely related to seabed topography and water depth [5]. - The discovery of suspected pockmarks, dissolution holes, and carbonate rocks suggests historical cold seep eruptions, providing key information for studying methane migration pathways in the Arctic region [5]. - The detailed investigations by the manned submersible enhanced understanding of the distribution patterns of Arctic deep-sea biodiversity and the adaptive mechanisms of ecosystems [5].
