Sea-ice motion and oceanographic data from the Beaufort Sea to the Chukchi Borderland in March - December, 2020

Sea-ice reduction is one of the most visible indicators of the Arctic warming. While there are many observations in the interior of the Arctic Ocean, oceanographic and sea-ice trajectory observations near the edge of sea-ice extent are rare. Here, we present oceanographic observations beneath sea ice obtained by an ice-tethered buoy and surrounding sea-ice motions obtained from 9 GPS buoys in the late ice-growth and sea-ice melt season along trajectories from the Beaufort Sea to the Chukchi Borderland in the Pacific sector of the Arctic Ocean.海冰消退是北极变暖最显著的表征之一。尽管北冰洋内部已有大量观测数据，但海冰范围边缘附近的海洋学与海冰轨迹观测仍较为匮乏。本文展示了北冰洋太平洋扇区从波弗特海至楚科奇边缘地带的航迹上，于海冰生长末期与消融期，通过系泊冰浮标（ice-tethered buoy）获取的冰下海洋学观测数据，以及由9个GPS浮标测得的周边海冰运动数据。
