Abstract : As part of a comprehensive program to study naturally occurring fluid motions in the marine environment at all time scales a meter has been developed which is capable of sensing high-frequency turbulence. This meter introduces a number of new features to the field of current measurement techniques. It does not disturb the fluid at the point of measurement. It measures the entire velocity vector. It takes a vector average of its measurements. The meter has been laboratory tested and used in the field. It was demonstrated that the current meter has the capability of operating effectively in the presence of a wave field and may be useful in the study of such types of fluid motion.
