Description:
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 part of the NOAA Climate Observation Program. The WHOTS mooring also
serves as a coordinated part of the HOT program, contributing to the goals of observing heat,
fresh water and chemical fluxes at a site representative of the oligotrophic North Pacific Ocean.
The approach is to maintain a surface mooring outfitted for meteorological and oceanographic
measurements at a site near 22.75°N, 158°W by successive mooring turnarounds. These
observations will be used to investigate air–sea interaction processes related to climate
variability.
This report documents recovery of the WHOTS-6 mooring and deployment of the
seventh mooring (WHOTS-7). Both moorings used Surlyn foam buoys as the surface element
and were outfitted with two Air–Sea Interaction Meteorology (ASIMET) systems. Each
ASIMET system measures, records, and transmits via Argos satellite the surface meteorological
variables necessary to compute air–sea fluxes of heat, moisture and momentum. The upper 155
m of the moorings were outfitted with oceanographic sensors for the measurement of
temperature, conductivity and velocity in a cooperative effort with R. Lukas of the University of
Hawaii. A pCO2 system was installed on the WHOTS-7 buoy in a cooperative effort with Chris
Sabine at the Pacific Marine Environmental Laboratory.
The WHOTS mooring turnaround was done on the University of Hawaii research vessel
Kilo Moana, by the Upper Ocean Processes Group of the Woods Hole Oceanographic
Institution. The cruise took place between 27 July and 4 August 2010. Operations began with
deployment of the WHOTS-7 mooring on 28 July. This was followed by meteorological
intercomparisons and CTDs. Recovery of WHOTS-6 took place on 2 Aug 2010. This report
describes these cruise operations, as well as some of the in-port operations and pre-cruise buoy
preparations.
