ApRES (Autonomous phase-sensitive Radio Echo Sounder) data around the Thwaites Glacier recovered in 2026

ApRES (Autonomous phase-sensitive Radar Echo Sounder) measures the radar reflection signal from the internal and basal interface of ice shelf. The radar return signals are used to estimate the basal melt rate under ice shelves. In early 2026, we recovered the raw data from 2 stations near the grounding line of Thwaites Ice Tongue.
