The Third Acoustic Surface Reverberation Experiment (AS REX III) took place from December 1993 to March 1994 at Site L (34°N, 70°W) in the mid-Atlantic. As part of this experiment, two moorings were deployed to measure the environmental background. A meteorological and oceanographic mooring was deployed to characterize the surface wind stress, buoyancy flux, and the current and temperature structure over the top 500 meters. A Seatex Wavescan buoy was deployed to characterize the directional wave spectrum. This report presents results from these moorings. Wind speeds up to 25 m/s were seen, with significant heat losses (up to 1050 W/m2) when cold continental air moved out over the warm Atlantic. The wave heights ranged up to 8 m, with significant wave heights of several meters persisting for relatively long periods. Wave height and period, nondirectional spectra, directional spectra and a typology of wave events are presented and related to surface forcing.

SOFAR float trajectories from an experiment to measure the Atlantic cross equatorial flow (1989-1990) Richardson, Philip L.; Zemanovic, Marguerite E.; Wooding, Christine M.; Schmitz, William J.; Price, James F. (Woods Hole Oceanographic Institution, 1992-08)Neutrally buoyant SOFAR floats at nominal depths of 800, 1800, and 3300 m were tracked for 21 months in the vicinity of western boundary currents near 6N and at several sites in the Atlantic near 11N and along the equator. ...
