Hydraulic Transmissivity Inferred from Ice-Sheet Relaxation Following Greenland Supraglacial Lake Drainages

Tuesday, Jun 29, 2021

New field observations and model experiments of the Greenland ice sheet, led by AOS Faculty Member Yao Lai, were published in a recent Nature Communications paper. They show changes during the melt season underneath lakes on the ice sheet, giving us a glimpse of the drainage network beneath the thick, high-elevation interior of the ice sheet. The authors find the transmissivity beneath the 1km thick ice sheet can change by two orders of magnitude between the early and mid-melt seasons.
