Short summary
The discovery of polar subglacial lakes, rivers and streams has opened a new frontier of science within a short span. We present a new environmentally friendly approach to study subglacial reservoirs based on the concept of freezing-in instrumented probes carrying a tethering power-signal cable. In January 2022, the probe was successfully tested in East Antarctica: it reached the base of the ice sheet and returned to the ice surface with samples of melted water from the basal ice.
