WHOI Hawaii Ocean Timeseries Station (WHOTS) : WHOTS-2 mooring turnaround cruise report

Abstract

The Woods Hole Oceanographic Institution (WHOI) Hawaii Ocean Timeseries (HOT) Site (WHOTS), 100 km north of Oahu, Hawaii, is intended to provide long-term, high-quality air-sea fluxes as a coordinated part of the HOT program and contribute to the goals of observing heat, fresh water and chemical fluxes at a site representative of the oligotrophic North Pacific Ocean. This report documents recovery of the WHOTS-1 mooring, deployed in August 2004 near 22.75°N, 158°W, and deployment of the WHOTS-2 mooring at the same site. Both moorings were outfitted with Air-Sea Interaction Meteorology (ASIMET) systems to measure, record, and transmit the surface meteorological variables necessary to compute air-sea fluxes of heat, moisture and momentum. In cooperation with R. Lukas of the University of Hawaii, the upper 155 m of the moorings were outfitted with oceanographic sensors for the measurement of temperature, conductivity and velocity. The WHOTS mooring turnaround was done on the Scripps Institution of Oceanography Ship Melville, Cruise TUIM-10MV. The cruise took place between 23 and 30 July 2005.
