Measurements and modeling of the shallow pore pressure regime at the Sigsbee escarpment: Successful prediction of overpressure and ground-truthing with borehole measurements

Evidence was obtained for potential shallow overpressures based on seafloor geomorphology and interpretation of multichannel seismic data. The morphology of deep-seated slumps in the Mad Dog area implies formation due to internal forcing. The combination of geomorphology, hydrogeology, and seismic interpretation were successfully used to predict both the magnitude and distribution of overpressure.
