Using seismic noise correlation to determine the shallow velocity structure of the Seattle basin, Washington
Arthur D. Frankel, Paul Bodin
2022, Open-File Report 2022-1108
Cross-correlation waveforms of seismic noise in the Seattle basin, Washington, were analyzed to determine the group velocities of surface waves and constrain the shear-wave velocity (VS) for depths less than about 2 kilometers (km). Twenty broadband seismometers were deployed for about 3 weeks in three dense arrays separated...

Long-term recovery of Mexican spotted owl nesting habitat after fire in the Lincoln National Forest, New Mexico
Tara D. Durboraw, Clint W. Boal, Mary S. Fleck, Nathan S. Gill
2022, Fire Ecology (18)
BackgroundDry mixed-conifer forests of the southwestern United States are experiencing rapid, anthropogenically driven fire regime change. Prior to the Euro-American settlement, most of these forests experienced frequent surface fires but are now vulnerable to uncharacteristically large, high-severity fires. Fire directly influences the structure and composition of these forests...

BFS—A non-linear, state-space model for baseflow separation and prediction
Christopher P. Konrad
2022, Scientific Investigations Report 2022-5114
Streamflow in rivers can be separated into a relatively steady component, or baseflow, that represents reliably available surface water and more dynamic components of runoff that typically represent a large fraction of total streamflow. A spatially aggregated numerical time-series model was developed to separate the baseflow component of a...

Catherine S. Jarnevich, Terri Hogan, Jennifer Sieracki, Christine Lipsky, John Wullschleger
Lewis H. Ziska, editor(s)
2022, Book chapter, Invasive species and global climate change
The US National Park Service mission includes conserving native species and historical landscapes ‘unimpaired for the enjoyment of future generations’. However, humans have increased the introduction of non-native species that can become invasive and which have harmful impacts on native species and landscapes. We revisit two previous papers, ‘Alien Species...

2022, Lithosphere (2022)
New zircon U-Pb ages for the Alabama Hills Granite in Owens Valley, eastern California, range from 103 to 102 Ma, nearly 20 Ma older than previously published zircon ages. The data preclude previously implied links between the pluton and the adjacent Late Cretaceous Mount Whitney Intrusive Suite. Geochronologic and isotopic data indicate...
Water-quality improvement of an agricultural watershed marsh after macrophyte establishment and point-source reduction
Sarah Fuller, Edward P Boswell, Anita M. Thompson, Dale M. Robertson
2022, Wetlands (42)
Green Lake, located in central Wisconsin USA within a watershed with land use dominated by agriculture, is listed as impaired under Sect. 303(d) of the Clean Water Act. The primary tributary, Silver Creek, is also impaired because of high total phosphorus (TP) concentrations. Silver Creek flows through a shallow marsh before...
Examining landowners’ preferences for a chronic wasting disease management program
Adam Landon, Kyle Smith, Louis Cornicelli, David C. Fulton, Leslie E. McInenly, Susan A. Schroeder
2022, Wildlife Society Bulletin (47)
Private landowners are key partners in chronic wasting disease (CWD) management, especially in landscapes where there is limited public ownership. In this study, we evaluated landowners' preferences for alternative hypothetical CWD management programs using a stated choice experiment. We were particularly interested in understanding preferences for the use of financial...
