Short summary

This study focuses on the long-term subglacial hydrological activity of the Recovery Ice Stream in East Antarctica. We update the outlines of reported lakes based on their recent activity and identify 14 new lakes. A 21-year record of elevation changes of these lakes is constructed using multi-mission altimetry data. We also reveal spatial variability in elevation change patterns within several typical individual lakes. Our hydrological network confirms hydraulic connectivity among these lakes.
