D. Chester et al., THE EDDY RADIATION-FIELD OF THE GULF-STREAM AS MEASURED BY OCEAN ACOUSTIC TOMOGRAPHY, Geophysical research letters, 21(3), 1994, pp. 181-184
The Gulf Stream System is one of the most important components of the
North Atlantic Circulation. Reciprocal acoustic transmissions have bee
n analyzed to determine the structure and variability of temperature,
current velocity, and relative vorticity in a region just south of the
Gulf Stream. Observational evidence is presented that the Gulf Stream
is the source of the energetic eddy variability found in the Atlantic
interior. Through highly nonlinear processes, eddy activity (energy)
radiates away from the Stream southward via Rossby wave packets.
