Operation and Maintenance Manual for the XBT Data Acquisition System

Abstract

The expendable bathythermograph (XBT) device is used extensively to obtain ocean temperature profiles at selected locations. Relatively recent interest in the mixing and energy propagation mechanisms of the upper mixed layers of the ocean requires the collection of thermal data at rates and accuracies greatly exceeding the capability of commercially available XBT equipment. The purpose, then, of this development was the creation of a very flexible system that could be software programmed to collect XBT data from one to four probes falling simultaneously or in rapid succession at data rates of up to 20 samples per second per probe. The system resolution is 0.01 deg C. This manual describes the functional operation, interconnections for system set-up, calibration procedures, and library operating programs of the developed system.
