Dynamic Boundaries of Antarctic Active Subglacial Lakes Reveal Underestimated Water Volume Change and Overestimated Lakebed Active Area

Geophysical Research Letters
This study revisited 158 documented active subglacial lakes across Antarctica, applying a height‐change anomaly delineation algorithm to CryoSat‐2 and ICESat‐2 satellite altimetry data to assemble a 14.75‐year (2010.5–2025.25) time series of active ...

Glacial lakes control ice flow: new insights from satellite SAR PO-SBAS observations in Duiya Glacier, southern Tibetan Plateau

International Journal of Digital Earth
This study investigates the effects of glacial lakes on the flow velocities of Duiya Glacier, southern Tibetan Plateau, by employing satellite Synthetic Aperture Radar (SAR) Pixel-Offset-Tracking Small-Baseline-Subset (PO-SBAS) technology. Duiya Glacier,

Monitoring Subglacial Lake Activity in the David Glacier Region, East Antarctica, Using a DInSAR Displacement Integration Approach

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Subglacial lakes significantly influence ice sheet dynamics, necessitating precise monitoring of their activity. This study presents a novel approach that integrates differential interferometric synthetic aperture radar (DInSAR) displacements from ...
