In its first year-and-a-half the Geophysics division won contracts with the U.S. Geological Survey to investigate the Denali Fault using the magnetotelluric (MT) method, and with the Nevada Star Resource Corporation to evaluate transient electromagnetic data over the Tangle Lakes ultramafic complex following up on a regional MT survey. Both field areas were in the central Alaska Range.

Other contract work included a resistivity survey undertaken to evaluate contamination issues at the Kodiak airport for URS Corporation. Ongoing work with the USGS included using the audiomagnetotelluric (AMT) method for groundwater investigations in Nevada and Utah.

Louise Pellerin is a faculty member of the Summer of Applied Geophysical Experience (SAGE), teaching electrical and electromagnetic methods and near-surface geophysics. SAGE is a unique educational program designed to introduce students in geophysics and related fields to "hands on" geophysical exploration and research. The program emphasizes both teaching of field methods and research related to a variety of basic and applied problems. SAGE is sponsored by the Los Alamos National Laboratory branch of the Institute of Geophysics and Planetary Physics , University of California.
