Oceanographic profile temperature, salinity and other measurements using CTD taken from the RONALD H. BROWN in the North Atlantic and Equatorial Atlantic from 2013-11-16 to 2013-12-05 (NODC Accession 0120702)

The November - December 2013 PIRATA (Prediction and Research Moored Array in the Tropical Atlantic) Northeast Extension (PNE) and Aerosols and Ocean Science Expedition (AEROSE) cruise RB-13-06 was designed to (1) Collect oceanographic and meteorological observations in the northeastern tropical Atlantic, (2) Recover and redeploy the PIRATA Northeast Extensions’ four Autonomous Temperature Line Acquisition (ATLAS) moorings, and (3) Recover and redeploy the TFlex mooring located near the 20°N, 38°W ATLAS mooring. The oceanographic component of (1) includes measurements of conductivity, temperature, pressure, oxygen concentration, and horizontal velocity from CTD casts and measurements of temperature and depth from XBT deployments. The majority of the measurements were acquired along the 23°W meridian, which samples the southeastern corner of the subtropical North Atlantic, a region of subduction that is important for the subtropical cell circulation; the Guinea Dome and oxygen minimum zone, where the subtropical and tropical gyres meet; and the tropical current system and equatorial waveguide. The meteorological component of (1) focused on measurements of atmospheric aerosols, temperature, water vapor, ozone, trace gases, winds, and other properties. All scientific goals of RB-13-06 were achieved.
