How level Is sea level?

Illustrates, through lab experiments, why all oceans do not have the same mean sea level. Shows a tide gauge and recorded graphs of the Pacific Ocean which indicate the mean sea level over a long period of time. Explains experiments of temperature difference vs. sea level, salinity vs. sea level, and air pressure vs. sea level.
