Yo,

Yo man. Mean sea level is almost an arbitrary point. It's picked for a best
fit of data. Mount Everest is not the tallest mountain when measured from
the center of the earth. Chimborazo in Ecuador is. The ocean has depressions
in it all over the place. Gravity is not the same over the earth's surface.
The world standard for sea level and the gravitational constant is located
here on Gilligans Island 10 meters from the stern of the Minnow, right next
to the Captain Neal shrine. The Professor keeps it calibrated on a daily
basis.
Hope this helps.
