This also results in uncertainty in the true positions of anomalous geopressure zones interpreted from seismic. hinckley times funeral notices

"WebMethod 2 - Use Mean Sea Level (0m) as the seismic reference datum. The trace data was originally processed using a SRD of 800m. The time traces have been shifted using replacement velocity of 2000 m/s from the original SRD of 800 m to a new 0 m MSL datum. In Configure project, set the SRD to 0m (MSL). In this example: 0 m = 0 ms. " - Seismic checkshot data
