Lamont Weekly Report, August 22, 2014
The beginning of the fall semester is around the corner, and members of the incoming class of graduate students in the Department of Earth and Environmental Sciences have been arriving throughout the summer. All but one will be here by the new student orientation on Tuesday of next week. Please join me in welcoming our 18 (mostly) new colleagues:

Tim Crone has just returned from chief scientist duties on a four-week, multi-institutional expedition on the R/V Atlantis to Axial Seamount on the Juan de Fuca Ridge. Tim led efforts to test a new suite of instruments and techniques for measuring heat and chemical fluxes at seafloor hydrothermal systems. The newly upgraded DSRV Alvin deployed two camera systems capable of measuring flow rates in focused and diffuse flow and collected ~10 days of temperature and flow rate data at the vent scale. The Woods Hole Oceanographic Institution’s Sentry AUV system surveyed a larger "box" around the vent field to measure flow rate and heat flux out of the system at the field scale. Tim writes, “We collected something in the vicinity of 24 terabytes of data, which I am now working to accommodate.” In appreciation for the successful work by the captain and crew of the Atlantis and the Deep Submergence teams, the expedition investigators presented them with a framed image of Alvin Rupes, a large tectonic landform on the planet Mercury that last year was named after the submersible (http://planetarynames.wr.usgs.gov/Feature/15127;jsessionid=6F2806970CCB52C9DCECD67E8497854A).
