An Electromagnetic Vorticity Meter.

reportActive / Technical Report | Accession Number: ADA302223 | Open PDF

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 instruments 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 .001s.
