Revised equation for sound speed in seawater consistent with long-range acoustic travel times.
Measurements of long-range acoustic travel times have suggested that the Del Grosso [(1974). J. Acoust. Soc. Am. 56, 1084-1091] (DG1974) and the internationally accepted Thermodynamic Equation of Seawater 2010 (TEOS-10, which is largely based on DG1974) sound-speed equations (SSE) in seawater give values at high pressu...
