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. 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.The first WHOTS mooring (WHOTS-1) was deployed in August 2004. WHOTS-1 was recovered and WHOTS-2 deployed in July 2005. This report documents recovery of the WHOTS-2 mooring and deployment of the third mooring (WHOTS-3) at the same site. Both moorings used Surlyn foam buoys as the surface element and were outfitted with two Air-Sea Interaction Meteorology (ASIMET) systems. Each system measures, records, and transmits via Argos satellite, the surface meteorological variables necessary to compute air-sea fluxes of heat, moisture and momentum. WHOTS-2 was equipped with one Iridium data transmitter, and WHOTS-3 had two Iridium data transmitters. 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 Revelle, Cruise AMAT-07, by the Upper Ocean Processes Group of the Woods Hole Oceanographic Institution and Roger Lukas' group at the University of Hawaii. The cruise took place between 22 and 29 June 2006. Operations on site were initiated with an intercomparison of shipboard meteorological observations with the WHOTS-2 buoy. Dr. Frank Bradley, CSIRO, Australia, assisted with these comparisons. This was followed by recovery of the WHOTS-2 mooring on 24 June. A number of recovered instruments were calibrated by attaching them to the rosette frame of the CTD. Shallow CTD profiles were taken every two hours for 12 hours on the 25 th of June. A fish trap was deployed on June 25 th by John Yeh, a University of Hawaii graduate student. The WHOTS-3 mooring was deployed on 26 June at approximately 22°46′N, 157°54′W in 4703 m of water. A ship-buoy intercomparison period and series of shallow CTDs followed along with a second deployment of the fishtrap.

The cruise took place between 23 and 30 July 2005. Operations on site were initiated with a 30-hour meteorological intercomparison period, followed by recovery of the WHOTS-1 mooring on 25 July. After offloading data and preparing some subsurface instruments for re-deployment, the WHOTS-2 mooring was deployed on 28 July at approximately 22°46′N, 157°54′W in 4695 m of water. A 31-hour intercomparison period followed. This report describes these operations, as well as some of the pre-cruise buoy preparations and CTD casts taken during the cruise.
This report presents velocity data from the Northwest Tropical Atlantic Station (NTAS) deployments 1 through 5, from March 30, 2001, to February 28, 2006. The NTAS project has maintained a series of moorings near 14 • 50 ′ N, 51 • 00 ′ W in the northwest tropical Atlantic for air-sea flux measurement. The moorings include a surface buoy outfitted with AirSea Interaction Meteorology (ASIMET) systems for determination of bulk air-sea fluxes and oceanographic sensors along the upper 120 m of the mooring line. This report describes and presents the velocity data recovered from current meters and Acoustic Doppler Current Profilers (ADCPs) during the first five years of the NTAS project.
