THE USE OF GEOPOTENTIAL HEIGHTS FOR GREAT LAKES VERTICAL DATUM,
Abstract
The study deals with a subject that the average civil engineer, without any geodetic orientation, would think of as 'levels'. The actual shape of the Mean Sea Level surface, however, is not readily amenable to description by a simple mathematical expression. If the waves, tides, currents, etc., be 'averaged out' and the sea level surface considered to be the quiet, undisturbed, smooth surface of the sea, a liquid in equilibrium, it will be immediately obvious that this surface will be everywhere normal to the direction of gravity. This is indeed the definition of the Mean Sea Level surface even when it is extended underneath the surface of the continents. (Author)
