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.
