Up to twice the amount of subglacial water that was originally predicted might be draining into the ocean – potentially increasing glacial melt, sea level rise, and biological disturbances.

Two Georgia Tech researchers, Alex Robel and Shi Joyce Sim, have collaborated on a new model for how water moves under glaciers. The new theory shows that up to twice the amount of subglacial water that was originally predicted might be draining into the ocean – potentially increasing glacial melt, sea level rise, and biological disturbances.
The paper, published in Science Advances, “Contemporary Ice Sheet Thinning Drives Subglacial Groundwater Exfiltration with Potential Feedbacks on Glacier Flow,” is co-authored by Colin Meyer (Dartmouth), Matthew Siegfried (Colorado School of Mines), and Chloe Gustafson (USGS).
