Footnote 1: [[https://github.com/journals/jc/c](https://github.com/journals/jc/c)]([https://github.com/journals/jc/c](https://github.com/journals/jc/c))uncertainty [5]. On the one hand, in terms of \"feeders,\" cyclone systems over the Southern Ocean have a direct influence on high latitude precipitation [6]. On the other hand, however, there is high confidence that the largest ice losses occurred along the northern tip of the Antarctic Peninsula, where the collapse of several ice shelves in the last two decades triggered the acceleration of outlet glaciers [7]. In the West Antarctic, a recent study revealed that flow accelerations across the grounding lines of the Amundsen Sea Embayment, the Getz Ice Shelf, and the Marguerite Bay on the western Antarctic Peninsula account for 88% of discharge increase in the last 7 years [8]. The Pine Island Glacier [9] together with the Thwaites Glacier [10] both attract scientists' attention for their retreating and calving behaviors. Those two glaciers were found to speed up continually, although the acceleration rates have been decreasing to 1% and 8% [11]. Consequently, the accelerated ice mass loss in the coastal regions of West Antarctica continues to outpace the gains made in the East Antarctic regions. Even in the East Antarctic, some glaciers will endure instability, such as the Byrd Glacier [12] and the Totten Glacier [13]. Previously studies confirm a couple of factors contributing to this status, such as marine ice-sheet instability [14], ocean thermal forcing [15], and surface melting [16]. Satellite measurements of Antarctic glacier velocities have been carried out since the 1980s [17].
