The Serbian mathematician Milankovitch first suggested that orbital cycles caused climatic changes that led to the ice ages, thus affecting sea levels (Boggs, 2001). Milankovitch Cycles are thus the sedimentary products of variations in the Earth's orbital behavior that produced periodic changes of climate which influenced sea level and depositional patterns and facies.
