Sea ice motion is an important factor affecting Arctic sea ice advection and spatial redistribution of mass balance. Based on the data collected by 66 ice-based drifting buoys deployed in the Arctic Ocean from September 2018 to August 2019, combined with atmospheric reanalysis data and passive microwave sea ice concentration product, we calculated the sea ice drifting speed, the ice-wind speed ratio and the inertial intensity of sea ice motion, so as to characterize the temporal and spatial changes of Arctic sea ice kinematic parameters over a full ice season, and analyse the correlation between ice-wind speed ratio and sea ice concentration. Seasonally, the sea ice drift speed in the Beaufort-Chukchi Sea, the central eastern Arctic Ocean and the central western Arctic Ocean showed a decreasing trend in autumn and winter and an increasing trend in spring and summer. Spatially, the Greenland Sea ((0.32 ± 0.06) m/s) had the highest sea ice drift speed, followed by the Fram Strait ((0.17 ± 0.07) m/s), and those in the Beaufort-Chukchi Sea ((0.14 ± 0.05) m/s), the central eastern Arctic Ocean ((0.09 ± 0.02) m/s) and the central western Arctic Ocean ((0.07 ± 0.03) m/s) were relatively low. On the monthly scale, the ice-wind speed ratio was mainly dominated by sea ice drift speed. The ice-wind speed ratio in the Fram Strait and the Greenland Sea was relatively larger, due to the strong ocean surface current. While the ice-wind speed ratio in the central western Arctic Ocean, the central eastern Arctic Ocean, and the Beaufort-Chukchi Sea was relative low and tended to be distributed between 0−0.02 with the increase in sea ice concentration. The monthly averaged IMI for all buoys was 0.158 ± 0.144, and the response of ice to wind and the inertial signal of ice motion gradually weakened during the autumn-winter transition and started to strengthen again in spring and summer. Therefore, both of the above parameters can be used as important indicators to indicate the consolidation of ice field.
