  40. Oceanographers Roger Revelle and John D. (John Dove) Isaacs on the dock discussing the research work that they will be doing for the Midpac Expedition (1950). This expedition involved Scripps Institution of Oceanography and the U.S. Navy which discovered the Mid-Pacific Mountain Range on the bottom of the Pacific Ocean and confirmed Darwin's theory about the origin of atolls. Scientists were surprised to find that the seafloor was young, deep and rocky, not flat, old and filled with sediments. Measurements of continental heat flow from the ocean raised questions about the history of the Pacific Ocean basin that were later answered by Plate Tectonics theory. 1950.

  50. Roger Revelle and Robert Dietz, co-chief scientists on the MidPac Expedition of 1950, discussing significance of lithified globigerina ooze dredged from western Pacific. The Cretaceous fossils enclosed indicated a much younger age than expected -- a mystery which remained unresolved until later explained by plate tectonics and continental drift. Shot 3 of 3
