中国第16次北冰洋考察任务圆满完成，执行考察的雪龙号和雪龙2号于9月29日返回上海1。本次考察历时3个月，在楚科奇海台、加拿大海盆等区域完成海洋环境综合考察1。
此次考察在多个关键领域取得重要发现1。研究团队发现加拿大海盆太平洋暖水注入增强、加克洋中脊新型热液羽流区和北冰洋高纬冰区较多极鳕幼鱼等现象1。同时获取了岩石圈电性结构完整记录，其中岩石圈底部界面深度约60公里，时间尺度记录跨越2500万年1。此外，参与考察的极地号和探索三号预计将在10月中旬返航1。
China's 16th Arctic Ocean expedition has successfully concluded its three-month mission, with the research vessels Snow Dragon and Snow Dragon 2 returning to Shanghai on September 29 1. The comprehensive oceanographic survey covered critical regions including the Chukchi Plateau and Canada Basin, yielding significant discoveries about Arctic marine conditions and geological structures 1.
The expedition identified several important oceanographic phenomena during its operations 1. Researchers documented enhanced inflow of Pacific warm water into the Canada Basin, discovered a new hydrothermal plume field at the Gakkel Ridge, and detected notably high populations of Arctic cod juveniles in the high-latitude ice regions of the Arctic Ocean 1. Additionally, the team obtained complete records of the lithospheric electrical structure, with measurements extending approximately 60 kilometers to the base of the lithosphere and spanning a geological timescale of 25 million years 1.
