Observations of Fine Scale Vertical Shear and Strain in the Upper Ocean

Abstract

This thesis addresses the vertical wavenumber frequency (m, omega) distribution of vertical shear and strain in the upper ocean. Part of the data set includes measurements from a newly-developed pulse-to-pulse coherent sonar. Chap. 2 discusses its design and performance. Chap. 3 investigates the effects of zooplankton distribution on Doppler sonars which use small ensonified volumes. A secondary data set of isopycnal vertical displacement (eta) was collected with a profiling CTD system. Vertical shear (del w/del z, del v/del z) and vertical strain (del m/del z) data are analyzed in Chap. 4. Shear spectra; Vertical strain spectrum; Theses.
