In findings embargoed for release on April 17, National Science Foundation (NSF)-funded researchers investigate the role of surface meltwater on the flow of the Greenland Ice Sheet and outlet glaciers.

The research was conducted by glaciologists Sarah Das, of Woods Hole Oceanographic Institution, and Ian Joughin, University of Washington and published in a pair of companion papers in the online journal Science Express this week.

NSF is making available to the news media b-roll video shot on the Greenland ice sheet and still photos, at print resolution, taken by the researchers.

The papers will be printed in Science magazine on May 9. Co-authors of the work include Mark Behn, Dan Lizarralde and Maya Bhatia of WHOI; Ian Howat, Twila Moon, and Ben Smith of UW; and Matt King of Newcastle University.

The research was funded by NSF, the National Aeronautics and Space Administration, Woods Hole's Clark Arctic Research Initiative, and its Oceans and Climate Change Institute.
