DescriptionGeneral correspondence of Dan McKenzie, Assistant Director in Research (ADR), Department of Geodesy and Geophysics, University of Cambridge, England, January-December 1975. The contents principally comprise various invitations for McKenzie to attend symposia, give talks or write articles, requests for preprints, correspondence with publishers, or fellow academics/scientists seeking McKenzie's opinion on their works, but also:

APRIL 1975
Geof King, [Tehran, Iran], setting up of the Atomic Energy Organization of Iran (AEOI), his colleague [Mansour] Niazi's irritation with Nick Ambraseys and John Tchalenko, as the latter has published a map in an Iranian journal but did not provide the fundamental accompanying epicentral data but is selling copies to members of the AEOI, King has had his Natural Environment Research Council (NERC) grant halved, sends apologies to Drum Matthews as he has not drawn the promised fault plane solution diagrams for him, 2 April 1975; Dallas Abbott, Research Assistant to John Sclater, Department of Earth and Planetary Sciences, Massachusetts Institute of Technology, Cambridge, Massachusetts, USA, is using the rotations in McKenzie's & Sclater's 1971 paper ["The evolution of the Indian Ocean since the late Cretaceous", 'Geophysical Journal of the Royal Astronomical Society', vol 24 (1971), pp437-528] to determine the palaeobathymetry of the Indian Ocean but has discovered that the poles for the Southwest India Ridge earthquakes are incorrect and sends the revised coordinates, is working with Pete Molnar on revising the 45-53 MY time period, 7 April 1975; copy letter to Frank Richter, Department of Geodesy & Geophysics, University of Cambridge, England, from Dennis Flanagan, editor of 'Scientific American', New York, USA, has been in contact with Jason Morgan and Kenneth Deffeyes who are also writing a paper for the journal on the same subject as McKenzie and Richter but not only do the pair see no conflict between the two articles, but urge McKenzie and Richter to publish [McKenzie, D & F Richter, "Convection currents in the Earth’s mantle", 'Scientific American', Nov 1976], 15 April 1975;

Administrative HistoryMcKenzie was scheduled to be at Woods Hole and MIT between 15 June-1 October 1975 therefore the correspondence during this period is very incomplete, particularly for September. For some of the letters sent to McKenzie between these months see October.
