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

Fossil coral cores taken from the Line Islands provide information about the strength of the El Nino Southern Oscillation (ENSO) for periods of time as much as 7,000 years ago. The paper rules track the direction of coral growth. (Georgia Tech Photo: Gary Meek)
