description Athelstan Spilhaus Overview
Athelstan Spilhaus (1911-1998) was a South African-born American oceanographer, geophysicist, and inventor whose career spanned academia and public service. He invented the bathythermograph, a device for simultaneously measuring ocean depth and temperature that became essential to Allied anti-submarine operations during World War II. In 1942 he designed the Spilhaus Projection, a world map centered on Antarctica that represents all of Earth's oceans as one continuous body of water. From 1957 to 1973, he wrote the syndicated newspaper comic strip 'Our New Age,' which explained scientific concepts to general audiences.
help Athelstan Spilhaus FAQ
What makes the Spilhaus world map look so unusual?
Athelstan Spilhaus designed the 1942 projection to show Earth's oceans as one connected body of water. Continents are pushed toward the map's edges and visibly split, reversing the land-centered emphasis of familiar Mercator maps.
What was the purpose of Spilhaus's ocean-centered projection?
The projection was intended to make the continuity of the global ocean immediately visible. It is especially useful for discussing currents, marine ecology, pollution, and the idea that the named oceans form one interconnected system.
Was Athelstan Spilhaus only a cartographer?
No. The South African-born American scientist was an oceanographer, meteorologist, inventor, and educator who lived from 1911 to 1998. He also helped develop the bathythermograph, an instrument used to record ocean temperature with depth.
Can the Spilhaus projection replace a normal navigation map?
It is primarily a conceptual and educational map rather than a practical road or navigation chart. Its interrupted continents and strong distortion near the outer edge are deliberate tradeoffs for keeping the world ocean continuous.
