Oceanic subcrustal flow toward the continents and constancy of global sea-level

Summary

From the conservation of the mass of the earth including the hydrosphere it can be concluded that continental growth has been connected with subcrustal flow from the ocean toward the continents. Calculations show that the volume of ocean bottom subsidence nearly equals to the volume of the uplifted continental masses above the level of the primeval ocean bottom. The sea level has not changed appreciably since Precambrian. Change of ocean bottom topography and emergence of continents do not effect global sea level. Transgression and regression are figurative terms and really indicate subsidence resp. uplift of the continental crust blocks around the shoreline.
