EK80 Water Column Sonar Data Collected During PC1803

During the PC-18-03 cruise, four moorings were turned around, whereby existing moorings and their instrumentation were recovered, and replaced by new and identical mooring at the same or a nearby location. The first work area is located in the northwestern tropical Atlantic ocean and includes the Northwest Tropical Atlantic Site (NTAS), which is occupied by a surface mooring, and the nearby Meridional Overturning Variability Experiment (MOVE) 1 site, occupied by a subsurface mooring. The second work area is closer to the Caribbean islands and includes two subsurface moorings at the MOVE 3 and 4 sites. NTAS is operated and serviced by the Upper Ocean Processes (UOP) group from the Woods Hole Oceanographic Institution (WHOI). All MOVE moorings are operated and serviced by the Scripps Institution of Oceanography (SIO). For calibration purposes, comparison between measurements from moorings and ship were made during the turn around cruise. ARGO floats were also be deployed during transit out of Mayport towards the NTAS site. R/V Pisces departed Mayport FL on May 30 and returned to Morehead City NC on June 21 2018.
