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

Thwaites Glacier's outer edge. As the glacier flows into the ocean, it becomes sea ice and drives up sea-level. Thwaites Glacier's ice is flowing particularly fast, and some researchers believe it may have already tipped into instability or be near that point, though this has not yet been established.
