ABSTRACT:
A benthic bobbing buoy system which includes an anchor, a buoy, and an anr line connecting the buoy to the anchor, the anchor line being of a length to establish the buoy at a submerged position. Another buoy for bobbing between the surface of the water and a submerged position is connected by another line to the submerged buoy. Provision is made for selectively changing the buoyancy of the bobbing buoy between a positively buoyant condition to a less positively buoyant condition, and provision is made for limiting the descent of the bobbing buoy when the bobbing buoy is less positively buoyant. With such an arrangement the bobbing buoy can repeatedly bob between the surface of the water and a predetermined depth.
