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 School of Earth and Atmospheric Scientist researchers — Alex Robel, assistant professor, and Shi Joyce Sim, research scientist — 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. (The research is also covered at SciTechDaily and Earth.com.)
