Calculate the P, and overpressure parameter 1, = P./S, with $ = 0.298. The total depth is 2000 m and the water depth is 500 m. Consider a lithostatic gradient of 22 MPa/km below the seafloor. Based on the experimental data, we know: B = 3.2 x 10-2 MPa-1 and 00 = 0.38. How much higher than the expected hydrostatic value is the pore pressure? (hint: calculate the total vertical stress first, calculate the effective vertical stress using , pore pressure using the relevant equation, and finally calculate the overpressure parameter) In(6/8), calculate the
