An empirical time-depth model for calculating water depth, northwest Gulf of Mexico

摘要: The velocity of sound in water varies nonlinearly with depth temperate and tropical ocean basins, limiting the accuracy representing a single average value. A seventh-order polynomial provides an empirical model for converting seismic travel time to northwest Gulf Mexico. This method works best continental slope where relief can vary markedly over salt structures, whereas application on shelf is limited by local seasonal variations velocity. Calculated depths may differ from those other techniques because difficulties interpreting competent bottom.
