Pan American Climate Study (PACS) Mooring Deployment Cruise Report R/V Roger Revelle Cruise Number Genesis 4
Abstract
Three surface moorings were deployed in the eastern equatorial Pacific from the R/V Roger Revelle as part of the Pan American Climate Study (PACS). PACS is study with the goal of investigating links between sea surface temperature variability in the tropical oceans near the Americas and climate over the American continents. The three moorings were deployed near 125 deg W, spanning the strong meridional sea surface temperature gradient associated with the cold tongue south of the equator and the warmer ocean north of the equator, near the northernmost, summer location of the Intertropical Convergence Zone. The mooring deployment was done to improve understanding of the air-sea fluxes and of the processes that control the evolution of the sea surface temperature field in the region. Two surface moorings of the Upper Ocean Processes Group at the Woods Hole Oceanographic Institution (WHOI) were deployed; one at 3 deg S, 125 deg W and the other at 10 deg N, 125 deg W. One mooring from the Ocean Circulation Group at the University of South Florida was deployed on the equator at 128 deg W. The buoys of the two WHOI moorings were each equipped with meteorological instrumentation, including a Vector Averaging Wind Recorder, and an Improved Meteorological (IMET) system. The WHOI moorings also carried Vector Measuring Current Meters, single point temperature recorders, and conductivity and temperature recorders located in the upper 200 meters of the mooring line. In addition to the instrumentation noted above, a variety of other instruments, including an acoustic current meter, acoustic doppler current meters, bio-optical instrument packages and an acoustic rain gauge, were deployed during the PACS field program.
