Geology and Minerals
Everett Dale Jackson (November 29, 1925 – July 28, 1978) was an American geologist. A graduate of the University of California, Los Angeles, where he earned his doctorate in 1960, he was involved with the geological training of astronauts, the planning and preparation of lunar exploration missions, and the dissemination of their discoveries. As co-chief scientist of the Deep Sea Drilling Project (DSDP) leg 55 that drilled the Hawaiian-Emperor seamount chain in 1977, he found the Hawaiian hotspot theory of its formation to be valid.
