SeaSoar and Doppler Sonar Spatial Survey of Internal Tide Generations, Surface Boundary Layer Dynamics, and Mixing

Abstract

During the AESOP (Assessing the Effects of Submesoscale Ocean Parameterizations) field program near Monterey Bay, our cruise from 29 July-28 August 2006 was divided into three segments: a frontal survey from 30 July-6 August, an offshore line to examine submesoscale decay away from the coast from 6-10 August, and an internal tide survey from 10-25 August. SeaSoar was towed behind a ship at 4 m/s and made sawtooth profiles to depths of 350-400 m. For the 2 frontal surveys we have calculated vertical velocity using the generalized omega equation including parameterizations of mixing. Statistics from offshore line will be compared to a high-resolution numerical simulation. For the tidal survey we produced a phase-averaged description of energy and mixing in a tidal beam over Monterey Canyon.
