Why does a block of wood held underwater rise to the surface when released?

Because the weight of the wood is less than the weight of an equal volume of water.
So when it's completely submerged, the upward buoyant force on it is greater than
the downward gravitational force on it. The wood accelerates in the direction of the
net force on it, exactly as one wood expect.

What is hydrographic surveying?
In civil engineering, measurement of earth surface under water. Eventually, it leads to calculation of volume of water held (or flowing through) depressions on earth surface. Since, underwater surfaces are not directly accessible for measurement a separate technology called sounding is used to measure the depth of surface from water surface. Sounding methods may vary from running a long string with a sink to the bed of water body to sending an ultrasonic vibration to measure the time of return.
