HARRY HAMMOND HESS 115 Harry Hess was a pioneer in development of the now widely accepted theory of ocean-floor spreading. In 1960, in a widely circulated report to the Office of Naval Research, Harry proposed that the mid-oceanic ridges were the loci of upwelling in 1969 indicates that it was the most referenced work in solid-
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.
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.
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.
the modern theory of seafloor spreading, subduc-tion and plate tectonics, Harry Hammond Hess and Stanly Keith Runcorn. Apart from hopefully provid-ing an in depth perspective on the origins of the sci-ence of mantle convection, this survey also reveals the rather fascinating historical ties many of these fa-
Unlike Wegener, Hess lived to see his major theory accepted. He helped to plan the U.S. space program. On August 25, 1969, he died of a heart attack. It was just a month after the Apollo 11 mission brought the first humans to the Moon. Harry Hammond Hess
