HIGH-FREQUENCY OVER-THE-HORIZON TECHNIQUES IN COASTAL RESEARCH.
In order to inexpensively telemeter environmental data from remote shelf waters, radio transmitters in the 2- to 6-megahertz (MHz) band are attached to freely drifting drogues. Bearing angles to the drogues are obtained at shore bases by using directional antennas to receive the ground wave transmissions from the drogues. Drogues have been tracked using this system in a variety of coastal situations. Mass fluxes determined by this method would have been prohibitively expensive to delineate using current meters. The system is also used to telemeter sea surface temperature to nearby shore stations as well as over extended distances.
