Abstract

Baffin Bay is located between Greenland and several islands of the Canadian Arctic, providing a conduit for the downstream transport of ice and freshwater to the North Atlantic via Davis Strait. Using satellite observations from Sentinel-1, the RADARSAT Constellation Mission, and CryoSat-2, we estimated the sea ice export through Davis Strait and winter ice production in Baffin Bay from 2016 to 2022. The average annual ice export for this 6-year period was 981 ± 193 × 10³ km² for area 816 ± 130 km³ for volume, and 653 ± 130 km³ for solid freshwater, all of which are considerably higher than previously reported estimates. The average winter ice area production upstream of Davis Strait was 758 × 10³ km² and the volume production was 589 km³ indicating that more than 80% of the ice exported out of Baffin Bay was produced locally. Compared to Fram Strait, sea ice fluxes through Davis Strait represent ∼59% of the volume and ∼111% of the area.

从哨兵-1、雷达卫星星座任务和 CryoSat-2 探测到的巴芬湾冰出口量和产量：2016-2022 年

巴芬湾位于格陵兰岛和加拿大北极地区的几个岛屿之间，是冰和淡水通过戴维斯海峡向北大西洋下游输送的通道。利用哨兵一号、雷达卫星星座任务和 CryoSat-2 的卫星观测数据，我们估算了 2016 年至 2022 年通过戴维斯海峡的海冰出口量和巴芬湾的冬季产冰量。在这 6 年期间，年均冰出口面积为 981 ± 193 × 103 平方公里，体积为 816 ± 130 立方公里，固体淡水为 653 ± 130 立方公里，均大大高于之前报告的估计值。戴维斯海峡上游冬季平均产冰面积为 758 × 103 平方公里，产冰量为 589 立方公里，这表明巴芬湾出口的冰有 80% 以上是当地生产的。与弗拉姆海峡相比，通过戴维斯海峡的海冰流量是其体积的 59%，面积的 111%。

期刊介绍： Geophysical Research Letters (GRL) publishes high-impact, innovative, and timely research on major scientific advances in all the major geoscience disciplines. Papers are communications-length articles and should have broad and immediate implications in their discipline or across the geosciences. GRLmaintains the fastest turn-around of all high-impact publications in the geosciences and works closely with authors to ensure broad visibility of top papers.
