An array of five surface moorings carrying meteorological and oceanographic instrumentation was deployed for a period of
two years beginning in June 1991 as part of an Office of Naval Research (ONR) funded Subduction experiment. Three eight month
deployments were carried out. The five mooring locations were 18°N 34°W, 18°N 22°W, 25.5°N 29°W, 33°N 22°W and 33°N 34°W.
Two Woods Hole Oceanographic Institution (WHOI) and three Scripps Institution of Oceanography (SIO) moorings
collected oceanographic and meteorological data, using a 3-meter discus or 2-meter toroid buoy and multiple Vector Measuring
Current Meters (VMCMs), an Acoustic Doppler Current Profiler (ADCP) and Brancker temperature recorders (tpods). The surface
buoys carried a Vector Averaging Wind Recorder (VAWR) and, on four of the five moorings, an Improved Meteorological Recorder
(IMET) which measured wind speed and wind direction, sea surface temperature, air temperature, short wave radiation,
barometric pressure and relative humidity. The IMET also measured precipitation. The VMCMs, ADCP and tpods, placed at depths
1 m to 3500 m, measured oceanic velocities and temperatures.
This report presents meteorological and oceanographic data from the WHOI Upper Ocean Processes Group (UOP) and the
SIO Instrument and Development Group (lDG) instruments and contains summaries of the instruments used, their depths, mooring
positions, mooring deployment and recovery times, and data return. Appendices contain information on supplementary Subduction
data sets.
