    Western Boundary Time Series cruise RB-12-01 (AB1202)
  • Description:
    This report summarizes the February 15 - March 5, 2012 cruise on the NOAA Ship Ronald H. Brown involving full-water-column CTD, lowered ADCP, and shipboard ADCP profiles conducted within the Florida Straits and east of Abaco Island, Bahamas. At each station, a package consisting of a Seabird Electronics Model 9/11+ CTD O2 system, an RDI 150 kHz Workhorse Lowered Acoustic Doppler Current Proler, a RDI 300 kHz Workhorse Lowered Acoustic Doppler Current Profiler, and 24 10-liter Niskin bottles, was to be lowered to the bottom. This report includes a description of the calibrations procedures and profiles of pressure, salinity (conductivity), temperature, and dissolved oxygen concentration. Water samples were also collected at various depths and analyzed for salinity and oxygen concentration to aid with CTD calibration. A total of 59 CTD-O2/LADCP stations were occupied and PIES data was downloaded from 5 sites. Mooring operations include recovery and redeployment of four tall moorings with a mixture of microcats and current meters, and five short moorings including a short upward looking ADCP mooring, a 400 m mooring with microcats and current meters, and three bottom landers instrumented with bottom pressure recorders. As part of NOAA contribution to the Global Surface Drifter Program, 15 surface velocity drifters equipped with sea-surface temperature sensors were deployed. A total of 48 XBTs were deployed in 24 simultaneous deployments (for Lockheed Martin/Sippican instrument development testing). Nine stations in the Florida Straits along 27N were occupied with 10-minute neuston net tows (in collaboration with John Lamkin, Southeast Fisheries Science Center). doi:10.7289/V57W6941(http://dx.doi.org/10.7289/V57W6941).
