2nd SEDI Symposium Held



Geomagnetism and paleomagnetism were the emphasis of the second SEDI (Study of the Earth's Deep Interior) symposium, “Reversals, Secular Variation and Dynamo Theory,” convened by Gary Glatzmaier and Paul Roberts at St. Johns College, Santa Fe, N.Mex., August, 6–10, 1990. The program included sessions on structure of the core and lower mantle and on mineral physics.

The organizers and participants of the meeting wish to thank the Institute of Geophysics and Planetary Physics and the Center for Nonlinear Studies at the Los Alamos National Laboratory, the Center for Earth and Planetary Interiors at the University of California, Los Angeles, and the Geophysics Program of the Earth Sciences Division of the National Science Foundation for their support of the symposium. What follows is a condensed summary of some of the highlights of the symposium, compiled by J . Bloxham, M. Brown, J . Cain, D. Fearn, D. Loper, and R. Merrill.
