An Electromagnetic Vorticity Meter.

Abstract

The Electromagnetic Vorticity Meter (EMVM) directly measures small scale vorticity in the ocean using the principles of electromagnetic induction. The scientific motivation for developing the EMVM, the design concept, and the theory of operation are discussed. Complete descriptions are given of the instrument's design, construction, and performance through several evolutions of the sensor, and extensive observations are presented of sensor performance during laboratory and field tests. The tests demonstrate a vorticity noise level of .001/s.
