1995 UTAM MIDYEAR REPORT

The mission of the Utah Tomography And Modeling/Migration (UTAM) consortium is to develop innovative tomography and imaging methods for exploration geophysics. Online titles of 1995 midyear reports are listed below, where IC stands for a paper with incomplete pictures in the postscript file.
