Vane Design for the Coastal Ocean Lagrangian (COOL) Float.

Abstract

Coastal Ocean Lagrangian (COOL) float is an isopycnal f/h float equipped with vanes to measure vertical velocity. Although isobaric vertical current meters have been previously developed and deployed, not much is known about how vane geometry affects the float's response to vertical velocities. We determined the sensitivity of the float's rotation rate to vertical velocity past it for different vane geometries. The float's response to size, number and area of vanes, and the distance the vanes were located from the body of the float were examined. While the float's sensitivity increases with decreasing distance of the vanes from the body of the float and decreasing angle of the vanes to the horizontal, the float's response does no depend on the number or size of the vanes.
