Description

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 19.

The papers included in this volume were originally presented at the International Woollard Symposium held at the Kahala Hilton Hotel in Honolulu, Hawaii, December 8 through December 10, 1974. The symposium honored Professor George P. Woollard on the occasion of his 66th birthday. It was cosponsored by the University of Hawaii, where Professor Woollard is Director of the University of Hawaii's Institute of Geophysics, by the U.S. Geodynamics Committee, by the Inter-Union Commission on Geodynamics of the International Council of Scientific Unions, and by the following Sponsoring and Organizing Committee: Philip H. Abelson; L. Thomas Aldrich; Orson L. Anderson; William E. Bonini; Edward C. Bullard; Ramon R. Cabre; S.J.R.M. Demenitskaya; Charles L. Drake; John I. Ewing; Maurice Ewing (Deceased); Richard A. Geyer; Alberto A. Giesecke; Wytze Gorter (Chancellor, University of Hawaii at Manoa); Anton L. Hales; John Brackett Hersey; Everett Dale Jackson; Gordon A. Macdonald; Henry W. Menard, Jr.; Robert P. Meyer; Julio Monges-Caldera; Jack E. Oliver; Frank Press; Russell W. Raitt; Donald A. Rice; George H. Sutton; Manik Talwani; G. B. Udintsev; Seiya Uyeda; Tjeerd H. van Andel; J. Tuzo Wilson; J. Lamar Worzel. The Organizing Committee set the theme and scope of the meeting: the symposium was to explore the edge of knowledge, in those fields of science that during the past decade have been the principal concern of Professor Woollard and his associates and students, of the Pacific Ocean basin and its margin. A Program Committee was charged with inviting papers from internationally known scientists, for the following sessions: Gravity and Geodesy Seismology Magnetism Marine Geology and Tectonics Volcanology and Petrology Tectonophysics.
