A benthic bobbing buoy system which includes an anchor, a buoy, and an anchor 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.

A benthic bobbing buoy system comprising: an anchor; a buoy; an anchor line connecting the buoy to the anchor; said anchor line being of a length to establish the buoy in a submerged position; another buoy for bobbing between the surface of the water and a submerged position; a bobbing line connecting the bobbing buoy to the submerged buoy; a weight connected to the bobbing line intermediate its ends for limiting the descent of the bobbing for cooperating with said bobbing buoy for forming a bobbing buoy-weight system buoy when the bobbing buoy-weight system is negatively buoyant; means for selectively changing the buoyancy of the bobbing buoy-weight system between a positively buoyant condition to a negatively buoyant condition; the length of the bobbing line between the submerged buoy and the weight means being represented by L1, and the length of the bobbing line between the weight means and the bobbing buoy being represented by L2; and L2 being greater in length than L1 so that during all positions of the bobbing buoy tension is maintained on all of the lines to prevent entanglement thereof.
