CABLE-TOWED OCEANOGRAPHIC INSTRUMENTATION SYSTEM DETAILED DESIGN

Abstract

Salient features are described of a cable-towed oceanographic instrumentation system designed for the taking of sound-speed measurements simultaneously and continuously at six depths, to a maximum depth of 5,000 feet from a vessel proceeding at 7 1/4 knots. A novel housing for the sound velocimeter, designed to minimize sound-speed measurement error due to towing speed, is described. The housing is used to prevent rotation of the cable. The equations for prediction of cable rotation are derived and measurement of the rotational characteristics of a double-armored cable are reported. Description is also given of the development of the electrical signal-transmission system, which incorporates a novel low-distortion amplifier.
