During 1957 a  long thermistor chain with twenty-three thermistors at intervals of  and towing winch were installed on the ship. The sensor system had been designed to allow continuous collection of temperatures at depth, particularly useful in study of ocean acoustics. The ship collected data in the western Atlantic coast from Nova Scotia to Charleston, South Carolina and into the Sargasso Sea.
In 1957, a series of thermistors spaced uniformly apart and accompanied by a towing winch were attached to the ship. This temperature-measuring system was designed to collect data continuously at depth, which is particularly useful for studying ocean acoustics. The vessel traveled along the western Atlantic coast from Nova Scotia to Charleston, South Carolina, and into the Sargasso Sea.
