Abstract : An array of oceanographic instruments is supported on a tension line extending horizontally at a selected ocean depth between a pair of vertical lines one of which is a ship-borne, end-weighted, winched cable and the other a float-supported and anchored guide line. To hold the array at a selected level, a buoyant package is moved along the guide line to a selected location where it grips the line and exerts its positive buoyant force. By matching positive buoyancy of the package to the negative buoyancy of the weighted cable, opposing, tension-producing forces are applied to the tension line to hold it in its horizontal disposition. The motive power for the buoyant package is supplied by the ship through its cable and the coupled tension line. The horizontal disposition of the array initially is achieved by moving both the cable and the buoyant package to the selected level. (Author)
