Caption from Oceanus online:
Laura Stevens leaps over a stream of meltwater atop the Greenland Ice Sheet. Stevens, a graduate student in the MIT-WHOI Joint Program in Oceanography, was lead author of a new study that identified a surprising trigger mechanism that causes large cracks to split open the bottoms of supraglacial lakes. The study was published in the prestigious scientific journal "Nature".

Image Of the Day caption:
MIT-WHOI graduate student Laura Stevens leaps over a stream of meltwater on the Greenland Ice Sheet. Stevens was part of team (including WHOI scientists Sara Das, Mark Behn, and Jeff McGuire) that identified a surprising mechanism that triggers large cracks to form in the bottoms of lakes atop the ice. Water surges through the cracks, draining the lakes within hours and sending a deluge thousands of feet through the ice down to the bedrock. The water lubricates the interface between ice and rock, allowing glaciers to slide faster, shed more ice into the ocean, and cause sea levels to rise faster.
