Evaluation of hypotheses for right-lateral displacement of Neogene strata along the San Andreas Fault between Parkfield and Maricopa, California
Richard G. Stanley, John A. Barron, Charles L. Powell II
2017, Scientific Investigations Report 2017-5125
We used geological field studies and diatom biostratigraphy to test a published hypothesis that Neogene marine siliceous strata in the Maricopa and Parkfield areas, located on opposite sides of the San Andreas Fault, were formerly contiguous and then were displaced by about 80–130 kilometers (km) of right-lateral slip along the...

Community distance sampling models allowing for imperfect detection and temporary emigration
Yuichi Yamaura, J. Andrew Royle
2017, Ecosphere (8) 1-15
Recent developments of community abundance models (CAMs) enable us to analyze communities subject to imperfect detection. However, existing CAMs assume spatial closure, that is, that individuals are always present in the sampling plots, which is often violated in field surveys. Violation of this assumption, such as in the presence of...

W. Miles, Richard W. Saltus, Nathan Hayward, D. Oneschuk
2017, Open File 7862
This map is a compilation of aeromagnetic surveys over Yukon and eastern Alaska. Aeromagnetic surveys measure the total intensity of the earth's magnetic field. The field was measured by a magnetometer aboard an aircraft flown in parallel lines spaced at 200 m to 10000 m across the map area. The...
Visualization of groundwater withdrawals
Richard B. Winston, Daniel J. Goode
2017, Open-File Report 2017-1137
Generating an informative display of groundwater withdrawals can sometimes be difficult because the symbols for closely spaced wells can overlap. An alternative method for displaying groundwater withdrawals is to generate a “footprint” of the withdrawals. WellFootprint version 1.0 implements the Footprint algorithm with two optional variations that can speed up...
