  7. Roger Revelle and Robert Dietz, co-chief scientists on the MidPac Expedition of 1950, discussing significance of lithified globigerina ooze dredged from western Pacific.

  22. Milton Nunn Bramlette (kneeling) and Roger Revelle (man without shirt) inspecting a coring device during the Capricorn Expedition (1952-1953). This expedition was the first Scripps expedition to use scuba divers to explore the Pacific. Research ships Horizon and Spencer F. Baird mapped seamounts and guyots and other features of the Pacific seafloor. Scientists studied the 35,400 foot deep Tonga Trench, the second deepest place in the ocean, and measured heat flow on the East Pacific Rise. 1953.
