Biographical and Historical Information

John I. Ewing is a geophysicist who was Chairman of the Department of Geology and Geophysics at WHOI. Ewing graduated from Harvard in 1950 with a bachelor of science degree in physics. He was at the Lamont-Doherty Geological Observatory of Columbia University following his graduation from Harvard, and was Associate Director and Adjunct Professor of Geology at Columbia from 1973 until his appointment as Chairman of the Department of Geology and Geophysics at WHOI in 1976. Ewing had worked at Woods Hole before and during his undergraduate days, and continued his association with WHOI scientists, serving as chief scientist on various cruises of research vessels Atlantis , Balanus , Caryn , and Crawford .

Ewing served on the advisory and planning committees of several large oceanographic projects including the Planning Committee and the Atlantic and Pacific Advisory Panels of JOIDES (Joint Oceanographic Institutions for Deep Earth Sampling). He was also a member of the Advisory Committee of the International Decade of Oceanographic Exploration of the National Science Foundation, the National Academy of Sciences Committee on Oceanography, and the National Academy of Sciences Committee on Seismology.

[Information taken from Press Release of January 7, 1976.]

Project ROSE was a large-scale multi-seismic experiment designed to study in detail the seismic structure of an ocean spreading center and fracture zone, and to observe how that structure changes with age. Besides WHOI, other participating institutions included UNAM, University of Washington, Scripps, OSU, Lamont, University of Wisconsin, University of Texas, University of California, Entre Oceanologique De Bretagne, and the Naval Oceanographic Office. The LASE project was a cooperative effort by Lamont-Doherty Geological Observatory, WHOI, and the Marine Science Institute of University of Texas. The principal objective was to test the performance of a long towed hydrophone array for studying the structure of continental margins.
