Hess 
|
Harry Hess was appointed a professor of Geology at Princeton University in 1932 and when the Second World War broke out, he saw active duty in the Pacific Ocean. His ship was equipped to make detailed soundings of the ocean floor and Hess kept notes on his observations. After the war, he continued his research into the mid-ocean mountain ranges and deep underwater valleys. He speculated that the sea floor was spreading out from vents in the cracks where hot magma oozed up to the surface. Harry Hess died in 1969, a month after Apollo 11 completed its successful mission to the moon. |
