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.

20 Μαΐ 2024 · Harry Hammond Hess, a professor of geology at Princeton University, was very influential in setting the stage for the emerging plate-tectonics theory in the early 1960s. He believed in many of the observations Wegener used in defending his theory of continental drift, but he had very different views about large-scale movements of the Earth.
1 Οκτ 2024 · In this paper, Hess, drawing on Holmes’s model of convective flow in the mantle, suggested that the oceanic ridges were the surface expressions of rising and diverging convective mantle flow, while trenches and Wadati-Benioff zones, with their associated island arcs, marked descending limbs.
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.
Hess's hypothesis offered a solution for the origin and development of mid-oceanic ridges, fit together much of the above data, and utilized his new model of oceanic crust and mantle.

20 Μαΐ 2024 · This question particularly intrigued Harry H. Hess, a Princeton University geologist and a Naval Reserve Rear Admiral, and Robert S. Dietz, a scientist with the U.S. Coast and Geodetic Survey who first coined the term seafloor spreading.
