Count Component Title Abstract
1 EM122 Water Column Sonar Data Collected During AT20 Cruise>Climate Variability and Predictability (CLIVAR) A22,A20 (AT20, EM122). The hydrographic surveys will consist of approximately 180 full water column CTD/LADCP casts along the trackline. Each cast will acquire up to 36 water samples on the upcast, which will be analyzed for salinity, oxygen, and nutrient concentrations. Water samples will also be analyzed during the cruise for dissolved inorganic carbon (DIC), pH, total alkalinity and transient tracers (CFCs and SF6). Additional water samples will be collected and stored for shore-based analysis of dissolved organic carbon (DOC), helium/tritium, 13C/14C, and chromophoric dissolved organic matter (CDOM). Underway measurements will include surface pCO2, temperature, conductivity, dissolved oxygen, fluorescence, various meteorological parameters, and bathymetry.

            1 Atlantis (AT) Atlantis (AT) The research vessel (R/V) Atlantis is owned by the U.S. Navy and operated by WHOI for the oceanographic community. It is one of the most sophisticated research vessels afloat, and it is specifically outfitted for launching and servicing the Alvin human occupied submersible. Delivered to Woods Hole in April 1997, Atlantis was built with six science labs and storage spaces, precision navigation systems, seafloor mapping sonar, and satellite communications. The ship's three winches, three cranes, machine shop, and specialized hangars were specifically designed to support Alvin and other vehicles of the National Deep Submergence Facility.
