The "Xiangyanghong 01" scientific research vessel set sail from Qingdao on October 10 to carry out China's 10th Arctic expedition. The expedition lasts 50 days and is expected to return to Qingdao on September 30.

       China's 10th Arctic Expedition was approved by the Ministry of Natural Resources, organized by the Polar Expedition Office of the State Oceanic Administration and led by the First Institute of Oceanography of the Ministry of Natural Resources. A total of 78 crew members from 13 units, including the First Institute of Oceanography of the Ministry of Natural Resources, participated in the voyage and the First Marine Research Institute of the Ministry of Natural Resources took part in the voyage Wei Zexun, deputy director of the institute, was the leader and chief scientist of the expedition team.

       Closely focusing on the role and status of the Arctic Sea in global climate change and other scientific frontier issues, this survey will implement a comprehensive marine survey combining long-term in-situ observation with scientific research projects, which will provide support for nine conventional marine environmental observations and 22 scientific and technological projects, and will be planned in the Bering Sea, Bering Strait and Chuko. The Qihai Sea, the Baltic Sea and other open sea areas of the Arctic Ocean in summer carry out a comprehensive survey of physical oceans, marine meteorology, marine chemistry, marine organisms and ecology, Marine Geology and geophysics.

       It is understood that the survey will obtain data related to physical oceans and marine meteorology, marine geology, topography, marine organisms and ecology, marine chemistry and other environmental factors; conduct in-depth investigations of the Arctic related marine ecological environment and biological resources, new environmental pollutants; and carry out Arctic ice in the context of global change. The investigation of the important frontier scientific problems such as the response process and mechanism of the cover and marine environment will accelerate the construction of the Polar Observation System in China, grasp the mechanism of rapid reduction of Arctic sea ice and its climatic and ecological effects, and carry out comprehensive assessment of the environment and climate in the Arctic region, so as to improve our scientific understanding and understanding of the Arctic. Providing technical support for tackling global climate change will provide scientists with a multi-circle, multi-disciplinary and multi-parameter integrated ocean exploration platform, and incorporate the investigation of the genesis and mechanism of polymetallic nodules into the investigation plan.
