DEVELOPMENT OF AN OCEAN DATA STATION TELEMETERING BUOY.
Abstract
This report presents results of tests and studies conducted at sea and ashore to develop a general-purpose telemetering oceanographic and meteorological buoy capable of gathering optimum quantities of data reliably for a minimum of one year while moored in any depth of water occupying any ice-free ocean data station in the world. The tests at sea have already shown that model data obtained in the hydrodynamics towing basin and wind tunnel ashore, and environmental limits set forth by the guidance committee, which were used to design the first two 40-foot-diameter prototype discus buoy hulls and the first preliminary moorings, are valid and realistic. The digital data-acquisition system will permit telemetry of a minimum of 100 oceanographic and 10 meteorological data channels over a minimum distance of 2,500 miles, upon command from shore. The best design choise is shortwave, ionospheric radiotelemetry. Actual experiments have verified this choice. Preliminary studies show that the system designed for ionospheric telemetry is entirely compatible with relay by equatorial (synchronous) satellite simply by installation of a transceiver and auxiliary antenna of proper frequency. The report also describes preparations for additional field tests to demonstrate acquisition of subsurface oceanographic data using instrument packages distributed down along the mooring line, interrogated and telemetering over a single electrical conductor in the line, entirely by inductive coupling to the conductor.
