The year, 2024, marks the 40th anniversary of Chinese research expeditions in the polar regions and the 25th anniversary of its Arctic research expeditions. China has conducted 14 national Arctic research expeditions. With the increase of understandings on the global impacts of the changes of Arctic climate system, especially on China’s weather and climate, and demands for commercial utilization of the Arctic sea routes, Chinese scientists have made great progresses on on-site and remote sensing observation technologies for Arctic Ocean, interaction mechanisms between atmosphere, sea ice, and ocean, the connection mechanism between the Arctic Ocean and other regions, and have achieved a series of research results. This study summarizes the research achievements by Chinese scientists in the above-mentioned aspects or beyond, identifies knowledge gaps, and based on this, discusses prospects and provides suggestions. From a perspective of observation, improving the observation capabilities of the Arctic Ocean in winter and the ocean under the ice, as well as floe-scale processes of sea ice and mesoscale and submesoscale processes of the ocean, is an urgent task to be addressed. Strengthening international cooperation is necessary for building a monitoring network for the Arctic marine environment. From a perspective of numerical simulation, the descriptive ability and parameterization scheme of sub-grid processes based on observational evidence need to be developed. From a perspective of cross-sphere interactions, in addition to the multi-media coupling within the Arctic Ocean that this review focuses on, the interaction between the Arctic Ocean and land or ice sheet (Greenland), especially the water cycle process, is also a scientific domain that needs to be considered, in the context of Arctic warming and humidification. From a perspective of climate effects, the physical mechanisms that affect the robustness of teleconnection need to be clarified.

Also shown are the ice concentration obtained on 17 September, 2023, with the annual minimum ice extent being observed, and the monthly averaged ice extent in September 1981–2010.

Figure 9. Evolution of the large-scale circulation in the Arctic Ocean: (a) Early period with a limited BG and a large extent of sea ice versus (b) Later period with an expansion of BG and dramatic retreat of sea ice. The salinity profile sections were obtained from (a) the drifting profiling platform with the drifting along the BG during 1988, available from the World Ocean Database at https://www.ncei.noaa.gov/products/world-ocean-database, and (b) the D-TOP with the drifting along the TPD during 2020–2022.

Figure 11. Comparison of average sea ice thickness during late summer (September 16–30, 2016), based on (a) CryoSat-2, (b) Combined Model and Satellite Thickness (CMST), and (c) Analysis (ANA). The ANA estimates incorporate both sea ice thickness and concentration observations for assimilation, whereas CMST assimilates only sea ice concentration during the summer.

Blue lines represent sea routes accessible for the open-water (OW) vessels, while red lines indicate routes for the vessels of Polar Class 6 (PC6). The color gradient and varying line width reflect the density (days per year) of overlapping routes at specific locations.
