There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Nearly a decade ago, global news outlets reported vast ice melt in the Arctic as sapphire lakes glimmered across the previously frozen Greenland Ice Sheet, one of the most important contributors to sea-level rise. A new study reveals the long-term impact of that extreme melt. Using a new approach to ice-penetrating radar data, a team of scientists, including Winnie Chu, assistant professor in the School of Earth and Atmospheric Sciences, has shown that this melting left behind a contiguous layer of refrozen ice inside the snowpack. Most importantly, the formation of the melt layer changed the ice sheet’s behavior by reducing its ability to store future meltwater.
