Abstract

The following paper describes a shipboard/towed instrumentation cable for making vertical temperature structure measurements in a program that focuses on the dissipation of temperature fluctuations in the upper 100 meters of the ocean as a function of lateral range. The instrumented cable is implemented with 30 thermistors molded into fairing components and spaced at 1 meter intervals. The system has an accuracy of + or - 0.01 deg C and a resolution of 0.001 deg C over a range of 20 degrees Celsius. With a thermistor response less than 0.1 sec and a 5 Hz data rate, a tow speed of 8 knots is possible. All data management is accommodated by a PDP-11/40 shipboard computer. (Author)
