A DOPPLER SHIFT FLOWMETER,
Abstract
A water current meter and the results of its use aboard the Floating Instrument Platform, R/P FLIP, is discussed. Water currents are measured by projecting a 9 MHz acoustic beam and measuring the doppler shift frequency in the backscatter from a small volume of water. Data were gathered at various locations in the Pacific Ocean. Measurements were made to determine the flow profile, the level and spectral content of returns at various depths to 700 m. The discussion of the instrument includes receiver noise, transmitter power and streaming from the transducer face. The development of an instrument that will measure two components of flow is presently underway. (Author)
