Water Column Velocity Function for the Gulf of Mexico

Abstract

Water column velocities derived from deep water Gulf of Mexico conductivity, temperature, and depth data has been modeled into a seventh-order polynomial to provide a function for seismic time to depth conversions. This model is most accurate in Gulf of Mexico water depths ranging from about 1,500 to 13,000 ft, away from anomalous areas of higher temperatures and salinity. The utility of this equation extends from geohazard assessments to augmenting incomplete velocity profiles for geophysical surveys.
