pablodecastillo is on a distinguished road

If i have a floating body under current, we guess a sphere there is a wave pattern and the flotation line will not be flat, so my question is; How is the hydrostatic pressure at the botton of the sphere. I known that it is rho*g*h, but the question is, "h" is the z_coordinate from 0 or the height of column water?
