Worldwide Echo-Sounding Correction Tables to Convert to Standard Velocity Depths

Metadata Updated: November 12, 2020

Echo-sounding tables (3rd Edition) were prepared by D.J.T. Carter of the Marine Information and Advisory Service (United Kingdom) for the conversion of raw echo-sounding measurements of ocean depths to values compensated for variations of sound speed with regional density profiles. The tables were computerized by Carter and offer standard velocity-depth corrections for 85 different regions covering the globe. The database consists of algorithms for determining correction zones by latitude-longitude, and interpolation tables for each zone.
