Abstract : This grant was targeted at the acquisition of seismic instrumentation to aid the University of Texas at El Paso (UTEP) geophysics group's efforts which involve conducting a wide variety of geophysical studies in the southwestern U. S. The objectives of these studies are to investigate lithospheric structure and seismic wave propagation in the area. The equipment described in the proposal has all been purchased and delivered and has already been put to use. Specifically, we purchased 10 REFTEK portable seismic recording units with GPS clocks, 3 broad-band seismometers, and a SUN workstation with and external disk drive. With this equipment, we are beginning a project in cooperation with the Phillips Laboratory to monitor earthquakes from teleseismic distances on the Colorado Plateau. Also, we employed our new equipment in a just completed major field effort, the Delta Force experiment, where a series of long profiles emanating from near NTS were recorded in May of 1994. One of these profiles lies along the NTS-WSMR transect, one of our ongoing efforts, and others tie to recent experiments in the region (PACE, BARGE, NPE/SSCD). Thanks to the cooperation of the National Science Foundation, Cal Tech was able to obtain funding to enhance this experiment with another shotpoint. The end result of these efforts is a series of interlocking seismic profiles which should greatly enhance our knowledge of lithospheric structure and wave propagation in the NTS region. A brief description of the Delta Force experiment follows.
