Observations of Near-Bottom Currents with Low-Cost SeaHorse Tilt Current Meters

Abstract

The SeaHorse TCM is a low-cost, easy to use, robust current meter based on the drag principle. Use of a large number of low-cost instruments would result in a new high spatial resolution view of the processes and to improve the ocean state prediction. The ultimate goal is to improve this technology by including expendable option with automatic data relay after deployment and to develop a global scale program of near-bottom current observations. The objectives are to improve the design of the instrument, evaluate its performance in comparison with other standard current meters, accumulate experience in its deployment/recovery/operation and to promote the use of such an instrument in various applications. We proposed to evaluate this instrument (which utilizes the hydrodynamic drag principle; Hoerner, 1965) in a number of settings in comparison with standard oceanographic equipment, to demonstrate the instrument's capabilities and to analyze its performance. Specifically, several organizations and researches were identified that are willing to try these instruments or assist in their evaluations. PI is responsible for assembling and modifying the instruments and required moorings, will participate in deployment/recovery and will analyze the observational data.
