The report describes the design, construction and field use of an underwater glider that functions as an instrument platform designed to be towed behind a ship. The glider is towed on a constant length cable with descent and ascent controlled by hydrodynamic lift on wings and control surfaces. An electronic feedback system enables the glider to maintain constant depth and to respond to commands for prescribed depth variation. The glider in the tests reported, carried temperature, depth and electrical conductivity transducers. The towing speed range was four to ten knots, with a depth range 0 to 100 feet. Sample data from exploration of the oceanic surface layer are also included.
