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

School of Earth and Atmospheric Sciences Assistant Professor Jennifer Glass blogs from the sea, off the coast of Western Mexico, aboard R/V Oceanus, owned by the National Science Foundation and operated by Oregon State University. "Six thousand feet below our ship, three tectonic plates are colliding," begins this blog post. "Like slow-moving conveyor belts, the Rivera and Cocos Plates creep under the North American Plate. Where the denser oceanic plates dip below the less dense continental crust, the Middle America Trench is formed."
