GOCE revealed the height of sea is not the same everywhere on Earth

New precision gravity data from ESA’s GOCE satellite revealed that the sea is lower heading north along the east coast of North America. Winds, currents, tides and different temperatures cause seawater to pile up in some regions and dip in others, so in fact, the
