This process is called plate tectonics, and it transformed the thinking of geologists. One of them, Harry Hess, was an instrumental figure in figuring out how plate tectonics worked. Hess possessed two valuable skills: careful attention to detail and the ability to form sweeping hypotheses.
Harry Hammond Hess (May 24, 1906 – August 25, 1969) was an American geologist and a United States Navy officer in World War II who is considered one of the "founding fathers" of the unifying theory of plate tectonics.
Harry Hess published 'The History of Ocean Basins' in 1962, outlining a theory of how tectonic plates can move which was later called 'sea floor spreading'. He identified the presence of mid ocean ridges, and that ocean trenches are where ocean floor is destroyed and recycled.
This unplanned wartime scientific surveying enabled Hess to collect ocean floor profiles across the North Pacific Ocean, resulting in the discovery of flat-topped submarine volcanoes, which he termed guyots, after the 19th-century geographer Arnold Henry Guyot.
Hess's first duty during the war was in New York City, estimating enemy positions in the North Atlantic. He then saw active duty, commanding an attack transport ship. He made four major...

His loyalty to Princeton influenced his calling the volcanoes "guyots" after the university Geology Building. Later, in 1957, Hess supported the Mohole Project (initiated by Walter Munk), to drill through the oceanic crust, deep into the earth's mantle.
