1990 PASSCAL/USGS/GSC Brooks Range Seismic Survey
Entry ID: PASSCAL_BROOKS2

[ Update this Record ]

Summary
Abstract: In the summer of 1990, the U.S. Geological Survey, Rice University and
the Geological Survey of Canada conducted a seismic experiment across
the Brooks Range, Alaska. The goal of the experiment was to produce a
high-resolution image of the crust and upper mantle of the Brooks
Range and flanking geologic provinces by combining reflection and
refraction techniques. Five deployments of vertical sensors recorded
63 shots at 44 different locations along a 315 km profile. The nominal
station spacing is 100 meters. Shot sizes varied from 100 lbs to 4000
lbs and the offsets varied from 0 to 200 km.
