Internal Waves in the Upper Ocean During MILE

Abstract

We describe the spectral analysis oftemperature and velocity measurements made in the northeast Pacific as part of the Mixed Layer Experiment (MILE) and attempt to relate the observed fluctuations to internalwave models of the upper ocean. From the inertial frequency to I cph there is good agreement between these upper-ocean data and typical deep-ocean observations as described by the WKB-scaled Garrett-Munk model. The largest deviations from the Garrett-Munk model occur in the vertical-displacement field at high frequency, 1-5
