Researchers use airborne radar to detect groundwater beneath Greenland glacier
Researchers have detected groundwater beneath a glacier in Greenland for the first time using airborne radar data. If applicable to other glaciers and ice sheets, the technique could allow for more accurate predictions of future sea-level rise. By Danielle Torrent Tucker
Melting glaciers and polar ice sheets are among the dominant sources of sea-level rise, yet until now, the water beneath them has remained hidden from airborne ice-penetrating radar.
With the detection of groundwater beneath Hiawatha Glacier in Greenland, researchers have opened the possibility that water can be identified under other glaciers from the air at a continental scale and help improve sea-level rise projections. The presence of water beneath ice sheets is a critical component currently missing from glacial melt scenarios that may greatly impact how quic
