Scripps Institute of Oceanography. During the 1950s, high bottom heat flow, young age of "guyots" (flattoped sea mountains), thinness of ocean sediments, patterns of fracture zones. Deep sea drilling program AMSOC and MOHO (1960-1970); ocean magnetic surveys. Long-term measurements of carbon dioxide at Scripps by Keeling; greenhouse effect. International cooperation in oceanography via ICSU-SCOR. Circulation mixing and expansion of ocean waters; equatorial countercurrent. Some outstanding geophysicists; turning points in geophysics: 1) Harald Sverdrup's work, 2) the IGY, 3) World War II and the coming of age of science (Federal government support of geophysics by the Office of Naval Research and the National Science Foundation); 4) geophysical modeling of the ocean/atmosphere interaction; 5) predictability of weather and ocean events. His concerns about government support of science; his areas of expertise and publication. Return to Scripps and his involvement in University development at San Diego; applied geophysics mission to Pakistan; population studies at Harvard. His family and private life.
