Harry Hess was an American geologist and a naval officer who proposed the theory of seafloor spreading in 1960. He also studied hydrothermal metamorphism, gravity anomalies, and deep sea drilling, and received many awards and honors in his field.
Harry Hess was a geologist who proposed the theory of seafloor spreading, which explained how the continents drifted and the ocean floor was recycled. He also contributed to the study of continental drift, mountain building, and the space program.
Learn about Harry Hess, a pioneer of plate tectonics who proposed the sea floor spreading theory in 1962. Find out how he used sonar to map the ocean floor and discovered mid ocean ridges and ocean trenches.
18 Νοε 2024 · The seafloor spreading hypothesis was proposed by the American geophysicist Harry H. Hess in 1960. On the basis of Tharp’s efforts and other new discoveries about the deep-ocean floor, Hess postulated that molten material from Earth’s mantle continuously wells up along the crests of the mid-ocean ridges that wind for nearly 80,000 km ...
20 Νοε 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.
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-
Seafloor spreading was proposed by an American geophysicist, Harry H. Hess in 1960. By the use of the sonar, Hess was able to map the ocean floor and discovered the mid-Atlantic ridge (mid-ocean ridge).
