Expendable Bathythermograph Evaluation.

Abstract

Expendable bathythermographs (BTs) were tested to determine the temperature indication accuracies attainable from their thermistor-bridge temperature sensing circuits and the depth accuracy obtainable from their procedure of utilizing a known BT sink rate to determine instantaneous depth. Laboratory and field testing provided information sufficient for an evaluation of the technical feasibility of the expendable BT concepts and also provided some indication of operational capabilities.
