  • Description:
    This report summarizes the November 21 - December 6, 2009 cruise on the RSS Discovery involving full-water-column CTD and lowered ADCP profiles, along with shipboard ADCP profiles, conducted within the Northwest Providence Channel and east of Abaco Island, Bahamas. No Florida Straits sections were planned due to the RRS Discovery not having clearances to enter U.S. waters. A package consisting of a Seabird Electronics Model 9/11+ CTD O2 system, a RDI 150 kHz Workhorse Lowered Acoustic Doppler Current Profiler, a RDI 300 kHz Workhorse Lowered Acoustic Doppler Current Profiles, and 23 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 35 CTD-O2/LADCP stations were occupied. PIES/CPIES operations were conducted from 5 sites, involving recovery, deployment and telemetry. Mooring operations include recovery and redeployment of 3 moorings with a mixture of current meters, Acoustic Doppler Current Profiles (ADCPs), and temperature/salinity recorders, and deployment of 2 bottom landers instrumented with bottom pressure recorders.
