Abstract:

Reciprocal acoustic transmissions made in the Northwest Atlantic have been analyzed to determine the general circulation of the region between Bermuda and Puerto Rico. Six tomographic transceivers were moored from March 1991 to March 1992 in the region centered at 25 deg N, 66 deg W during Acoustic Mid- Ocean Dynamics Experiment AMODE. The goals of the research performed under this contract have 1 to study large-scale 300 to 1000 km circulation and variability in temperature, current, and relative vorticity fields, 2 to study mesoscale eddy kinematics and dynamics, and 3 to study the value of integral constraints on eddy-resolving numerical ocean models. Large-scale range averages over 300 to 700 km sections of temperature and velocity and large-scale areal averages over regions comprising 100,000 sq km of relative vorticity in the upper 3500 m of the water column have been estimated through inversion of the tomographic travel time data.
