In the United States work has been done by Woods Hole Oceanographic Institution, Lamont Geological Observatory and Scripps Institution of Oceanography; in England by the Department of Geodesy and Geophysics of the University of Cambridge; and in the by the Institute of Geophysics and the Institute of Oceanology. Examples of travel-time plots taken from published work of these labora- tories are illustrated in Figs. 2-8. Fig. 2 represents a radio-sonobuoy station of
