EVALUATION OF THE EXPENDABLE SURFACE CURRENT PROBE (ESCP)
An evaluation of an expendable surface current probe (ESCP) was conducted by the Coast Guard Research and Development Center using operational units in the First, Seventh, and Thirteenth Districts. A total of 86 probes were tested under simulated search and rescue (SAR) conditions using Coast Guard surface vessels ranging from 40 to 210 feet in length, and from HH-3F and HH-52A helicopters. The evaluation of the ESCP shows that the probe can be launched easily from Coast Guard ships and helicopters; the probe provides an accurate measurement (plus or minus 0.2 knots) of the surface current, quickly and inexpensively, in a broad range of weather and sea surface conditions. The overall performance of the ESCP indicates that it should become the most effective empirical measure of the surface current during a SAR case.
