摘要	As the Arctic Ocean continues to warm, both the extent and thickness of sea ice have dramatically decreased over the past few decades. These changes in ice have an impact on sea ice motion, including sea ice inertial oscillations (SIIO). However, the spatial pattern and temporal variations of Arctic SIIO remain poorly understood. In this study, the spatiotemporal characteristics of Arctic SIIO between 1979 and 2019 are revealed based on the sea ice drifting buoy dataset from the International Arctic Buoy Program (IABP). The results indicate the significant enhancement of SIIO during 1979-2019, with the trend of 7.84 x 10(-3) (+/- 3.34 x 10(-3)) a(-1) (a(-1) means per year) in summer and 1.92 x 10(-3) (+/- 0.80 x 10(-3)) a(-1) in winter. Compared with the first 30 years, the magnitude of SIIO in 2009-2019 increases by 66% in summer and 21% in winter. Spatially, the remarkable enhancement of SIIO during 2009-2019 is found in most of the Arctic Ocean. Especially in summer, SIIO are significantly intensified in marginal seas, including the Beaufort Sea, East Siberian Sea and Laptev Sea, which is mainly correlated with the decrease of sea ice concentration in recent years. This study is anticipated to provide insights for spatiotemporal variation of Arctic sea ice inertial motion in recent decades.
