Soundings are read at equal time intervals, and usually every ten minutes, and in some cases at each break in slope. They are written along the ship's track as often as space permits. Sounding are based on a sound velocity of 800 fathoms/second and are corrected only for the depth of transducer. Submitted to the Office of Naval Research under Contract Nonr-4029 (00) NR 260-101.
