Abstract
A buoy system for obtaining oceanic data from a predetermined depth to the urface includes an instrument vehicle programmed to cycle between predetermined positive and negative buoyancy conditions. A flexible tether having a degree of stiffness and a positive buoyancy factor distributed along its length is connected between a subsurface buoy and the vehicle so as to provide an increasing upward force on the negatively buoyant vehicle as it sinks toward a hovering depth at which the upward force of the buoyant tether balances the negative buoyancy of the vehicle.
