摘要：Despite its central role in the global climate, the Southern Ocean circulation is still one of the least understood ocean circulation systems of the planet . One major constraint to our understanding of this region is the challenge of observing ocean circulation in the seasonally sea ice sector of the Southern Ocean . Here, we present a new Sea Level Anomaly (SLA) product, focusing on the subpolar Southern Ocean and including its sea ice covered parts from 2013 to 2019. Combining observations from multiple satellites, including Cryosat-2, Sentinel-3A, and SARAL/AltiKa, processed with state-of- the-art algorithms, allows an improvement in spatial and temporal resolution compared with previous products . Validation is made by comparing our estimate with existing SLA products, cross-comparing estimates from individual satellites in the sea ice zones, and comparing the time series of the productwith a Bottom Pressure Recorder in the Drake Passage .
