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)
(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. ...
