The Acoustic Surface Reverberation Experiment:Water Velocity Data
Listed in NASA Earthdata CMR
The 1991 Acoustic Surface Reverberation Experiment (ASREX 91), funded by the Office Of Naval Research, took place in the eastern North Pacific, about 500 km from the coast of Vancouver Island, British Columbia.
Description
The water depth was approximately 3000 m. The Upper Ocean Processes Group deployed three oceanographic moorings as part of an experiment aimed at understanding near-surface acoustic reverberation in high sea states.
Two of the moorings were dedicated to the measurement of surface waves. The third measured meteorological and oceanographic variables. The deployment period, during the winter of 1991-1992, was characterized by high winds and large waves.
