Measurement of Sea Surface Elevation

- The hydrostatic pressure (used in Oceanography) is the pressure due to the water column above a given level (depth), which implies that p = 0 when the level is the free surface, which is at atmospheric pressure.

- Fundamental Equation of Hydrostatic describes the pressure variation, p, with depth, z, in a column of fluid:

p = g z z =p/ g
