A NEUTRALLY-BUOYANT, CONTINUOUSLY SELF-RECORDING, OCEAN CURRENT METER FOR USE IN COMPACT, DEEP-MOORED SYSTEMS

Abstract

A continuously self-recording current meter for deep ocean measurements is described. It has near-neutral buoyancy, is of small size for use on miniaturized subsurface moored systems, and is made mostly of stock item components. The main features are its utmost simplicity, low cost, and reliability of recording. Recording is made on a miniature chart recorder capable of running for over two months. Noise on the records, principally originated by mooring line motions, is filtered visually during the data- reduction phase. Data are digitalized by semiautomatic methods before being fed to an electronic computer for analysis.
