Imaging the earth— the quest for resolution

The international workshop, “Seismic Imaging and Parameter Estimation in Heterogeneous Media,” took place April 20, 1990 in Salvador (Bahia), Brazil. This workshop was sponsored by the Brazilian Geophysical Society, Petrobras, and the Federal University of Bahia. The host institution was PPPG (the geophysics department for graduate studies and research). The organizing committee included M. Botehlo, V. Cerveny, S. Freire, M. Porsani, E. Sampaio, and A. Weglein whose extensive efforts insured this workshop’s success. The committee is planning, as its final duty, to publish the presented papers and excerpts from the panel session as a formal Proceedings.
