Study of Earth's deep interior



More than a decade has passed since the very successful 1971 meeting on the coremantle interface that was organized by Allan Cox at the Florida Institute of Technology in Melbourne [Cox and Cain, 1972]. The rationale of that meeting was to bring together workers in several different disciplines that normally do not interact at scientific gatherings. In recognition of the facts that significant advances in our understanding of Earth's deep interior have taken place since that time but that there is yet the problem of combining data and theories from disparate geophysical disciplines, a group met during the Prague meeting of the International Union of Geodesy and Geophysics (IUGG) and formed an ad hoc consortium named “ISECALM” (International Study of the Earth's Core and Lower Mantle). One of the principal instigators of this initiative was Ray Hide (U.K. Meteorological Office, Bracknell), who was also instrumental in organizing the 1971 core-mantle meeting.
