According to the USGS, about 71% of the Earth’s surface is water-covered with oceans holding about 96.5% of all Earth’s water.
This inspired a series of maps in 1942 by oceanographer and geophysicist Athelstan Frederick Spilhaus which can be found in his book: Atlas of the World with Geophysical Boundaries Showing Oceans, Continents and Tectonic Plates in Their Entirety
“In order to realize this one the author uses the principles of the two following projections. The projection of Ernst Hammer and that of August Heinrich Petermann (co-author with Hermann Berghaus and Carl Vogel from Atlas Stieler).

The deformation is such that the American and Asian continents are completely torn apart. Europe, Africa and South-East Asia, on the other hand, maintain a coherent form . This projection is rarely used and it is a shame!”
