Stegen, G. R., K. Bryan, J. L. Held, and F. Ostapoff, 1975: Dropped horizontal coherence based on temperature profiles in the upper thermocline. Journal of Geophysical Research, 80 (27), 3841-3847.

Abstract: A series of 66 temperature profiles taken in the open ocean 350 km north of Puerto Rico are analyzed to determine the displacement spectrum and the dropped horizontal coherence. The results are not inconsistent with the Garrett and Munk model. One interesting exception is a tendency for the horizontal coherence not to fall off monotonically with decreasing vertical scales.
