Development and Performance of a Vector Measuring Current Meter (VMCM),

Abstract

To develop the capability of making accurate measurements of horizontal velocity in the upper ocean a vector measuring current meter (VMCM) has been developed. Orthogonal cosine response propeller sensors directly measure vector performance. A flux gate compass senses the instrument heading, and the velocity components are vector averaged and recorded on cassette tape. The instrument has the capability of one year long deployment at depths of up to 5000 m. Laboratory tests have documented the performance of the VMCM, and both laboratory and field results show that the VMCM is capable of making accurate measurements of horizontal velocity in the upper ocean.
