Short summary
The average height of the sea surface is important to understand if we are to accurately understand either the dynamic ocean or improve our understanding of the shape of the earth's surface. Currently we have been able to understand this to a certain degree, but with data from the new Surface Water and Ocean Topography (SWOT) satellite, we are now able to map the sea surface at a very small scale. We utilize this new data to better understand and map the shape of the global oceans.
