Although the monitoring of black-footed ferret (Mustela nigripes) populations following reintroductions has not been haphazard, several ferret recovery groups since 1994 have recommended development of uniform standards prescribing minimum methods, intensities, and frequencies of monitoring that would provide data on population size, mortality rates, and recruitment. Such standards would promote...
Spatial correlation of shear-wave velocity within San Francisco Bay Sediments
E.M. Thompson, L.G. Baise, R. E. Kayen
2006, Conference Paper, GeoCongress 2006: Geotechnical Engineering in the Information Technology Age
Sediment properties are spatially variable at all scales, and this variability at smaller scales influences high frequency ground motions. We show that surface shear-wave velocity is highly correlated within San Francisco Bay Area sediments using shear-wave velocity measurements from 210 seismic cone penetration tests. We use this correlation to estimate...
