Internal wave observations from FLIP in MILDEX.

Abstract

The research platform FLIP participated in the Mixed Layer Dynamics Experiment (MILDEX), off the coast of Southern California. Equipment included an array of 6 Doppler sonars and a repeatedly profiling CTD. Slant velocity estimates from back-to-back sonar beams were combined to form estimates of horizontal velocity and its vertical derivative, shear. These were compared with isopycnal vertical displacement and strain, derived from the CTD measurements over a 10 day period in the range 200 to 300 m depth. Power spectra of shear strain and geocentric acceleration are presented.
