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

Even as some parts of West Antarctica rapidly melt, raising sea level, large swaths of the ice remain stable for the time being. Scientists have now explored one of those stable spots — an isolated nook where the ocean meets the ice. This environment is “really at the edge” between melting and freezing, says Justin Lawrence, Ph.D. student with the School of Earth and Atmospheric Sciences. The delicate balance between these two processes is shaping the ice into those strange textures, and the result, at Kamb Ice Stream, is that massive cracks in the underside of the ice appear to be freezing back together. Ben Hurwitz, Ph.D. student in Ocean Science and Engineering, and Anthony Spears, Ph.D. student with the School of Electrical and Computer Engineering, also contributed to the study, published in Nature Geoscience. (The study was also covered at Astrobiology.com and AZO Robotics.)
