THE SPILHAUS WORLD OCEAN MAP
The Spilhaus World Ocean Map in a Square presents Earth’s oceans as a singular, uninterrupted body of water—which they truly are. This unique, ocean-centric perspective of our world was first published
in November 1979 by Athelstan F. Spilhaus (1911–1998), a South African–American geophysicist and oceanographer, in collaboration with Robert Hanson and Erwin Schmid, two geodesists of the former US Coast and Geodetic Survey.
