Abstract : This report presents our progress, to date, towards the development of an expendable profiler to measure the vertical gradient of horizontal velocity on scales small enough to produce profiles of the viscous dissipation of kinetic energy in the ocean. The proposed instrument consists of small-scale velocity shear sensor and a thermistor mounted on a modified version of a Sippican Expendable Bathythermograph (XBT). The major development problems and our attempts towards solving these problems are discussed along with a proposed design which will shortly be available for testing. The sensed parameters, shear and the temperature, are telemetered to the surface by FM telemetry up a standard XBT wire link.
