Shear Data Descriptions.

Abstract

Personnel from Science Applications, Inc. (SAI) and the Naval Research Laboratory (NRL) are working jointly on a description of shear in the upper ocean. SAI is focusing on vertical variability of vertical shear based on data obtained from free-fall velocity profilers. NRL is focusing on horizontal variability of both vertical and horizontal shear based on Lagrangian drifters. Another NRL data set resulting from simultaneous measurements with a Doppler sonar instrument and expendable current profilers will be described, but may not be processed in time for inclusion in this project. The purpose of this project is to assess the utility of combining the horizontal and vertical descriptions into a more comprehensive picture of upper ocean shear. Particular emphasis is to be placed on the distribution of Richardson number. The purpose of this progress report is to briefly describe the range of applicability of each data set and outline ways in which they may be related. (Author)
