  • Description:
    This report summarizes the May 8 - May 24, 2017 cruise on the UNOLS ship R/V Endeavor from Fort Lauderdale, FL to Fort Lauderdale, FL involving full-water-column CTD and lowered ADCP profiles, along with shipboard ADCP profiles, conducted within the Northwest Providence Channel, 27◦N 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 Profiler, a RDI 300 kHz Workhorse Lowered Acoustic Doppler Current Profiler, and up to 24 10-liter Niskin bottles, was lowered to the bottom. This report includes a description of the calibration 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 concentrations to aid with CTD calibration. A total of 44 CTD-O2/LADCP stations were occupied. PIES/CPIES operations were conducted at 7 sites, including three successful recovery and deployments of PIES at sites A, A2, and E. There was also the recovery of a PIES at site C that is part of the Adaptable Bottom Instrument Information Shuttle System (”ABIISS”) and the recovery of an older PIES at site A2. Mooring operations included recovery and redeployment of 3 tall moorings with a mixture of microcats and current meters and a bottom lander. A new expendable bathythermograph (XBT) recording board designed by the Atlantic Oceanographic and Meteorological Laboratory (AOML) engineering group was tested with twelve probe launches simultaneous with twelve CTD casts. Note: Bahamian clearances were obtained with a waiver of port entry before and after the cruise.
