This type of map is also sometimes referred as a world map from a fish’s point of view.
From the map:
Invented in 1942 by oceanographer Athelstan Spilhaus, the cartographic projection of the same name allows us to see the world through the eyes of a marine organism. The 70.8% of water on Earth forms, clearly shown here, an immense continuum, a large continuous body of water, varying in temperature and salinity according to currents and the ebb and flow of the seasons.

Spilhaus Projection Connecting the World Oceans
This projection helps visualize that our oceans are more connected than we often perceive. It is a ‘single map’ that connects the ‘blue’ part of the world, rather than the ‘green,’ offering new insights to understand our oceans as a continuum.
This map also makes a good planning tool for those who want to sail the world, move cargo, and understand the scientific relationships that coexist between these massive bodies of water.
