    Oceanographic instrumentation represents one of the most important problems shared by the ocean engineering and marine sciences communities. In comparison with other areas of technology-notably with the aerospace fields-the state-of-the-technology in oceanographic instrumentation is still relatively primitive. Continuation of this situation is intolerable as it produces unreliable data and is wast... View full abstract»

    Rapid advances in technologies useful to the Coast and Geodetic Survey (C&GS), larger responsibilities within the new organizational pattern of the Environmental Science Services Administration, and the anticipated growth of responsibilities in oceanography call for vigorous improvement of the technological systems of C&GS to meet future needs. A study performed in 1966 revealed many opportunities... View full abstract»

    Present methods of telemetering data from the oceans by low-frequency over-water paths are unreliable and require high-powered transmitters and large platforms. The Interrogation, Recording, and Locating System (IRLS) has been developed for satellite interrogating and locating land-based moving platforms via the UHF band. This paper describes the feasibility of utilizing the IRLS system for oceano... View full abstract»

    An analysis is made of the performance characteristics of a salinity/temperature/depth (STD) system manufactured by Bissett-Berman Corporation and used widely for oceanographic measurements. Particular attention is given to the influence of ambient vertical temperature gradient and rate of instrument descent on the registrations of salinity. An equation is derived for adjustment of indicated salin... View full abstract»

    A Doppler current meter was developed to provide an instrument for the measurement of water-flow velocity. This type of instrument detects the Doppler frequency shift which occurs in the acoustic signal received from reflections from moving microscopic particles in water which are excited by an acoustic beam of high-frequency energy. Mechanical inertias are minimal and there are no moving parts, s... View full abstract»

    A 24-foot compliant-tube parabolic reflector, with a flextensional transducer at its focus, has yielded acoustic source levels up to 122 dB¿baryd1 at 420 Hz in 85 feet of water off Fowey Rocks near Miami, Fla. The projector is part of a research program to study underwater sound propagation and related environmental parameters. Modulation signals of continuous wave pulses and pseudorandom sequenc...
