Sebastian Uhlemann, Baptiste Dafflon, Haruko Murakami Wainwright, Kenneth Hurst Williams, Burke J. Minsley, Katrina D. Zamudio, Bradley Carr, Nicola Falco, Craig Ulrich, Susan S. Hubbard
2022, Science Advances (8)
Bedrock property quantification is critical for predicting the hydrological response of watersheds to climate disturbances. Estimating bedrock hydraulic properties over watershed scales is inherently difficult, particularly in fracture-dominated regions. Our analysis tests the covariability of above- and belowground features on a watershed scale, by linking borehole geophysical data, near-surface geophysics,...
Determination of optimal set of spatio-temporal features for predicting burn probability in the state of California, USA
Javier Andres Pastorino Gonzalez, Joseph Willliams Director, Ashis K Biswas, Todd Hawbaker
2022, Conference Paper, Proceedings of the 2022 ACM Southeast Conference
Wildfires play a critical role in determining ecosystem structure and function and pose serious risks to human life, property and ecosystem services. Burn probability (BP) models the likelihood that a location could burn. Simulation models are typically used to predict BP but are computationally...

Nicholas Corson-Dosch, Michael N. Fienen, Jason S. Finkelstein, Andrew T. Leaf, Jeremy T. White, Joshua Woda, John Williams
2022, Scientific Investigations Report 2021-5112
In southeastern New York, the villages of Ellenville, Wurtsboro, Woodridge, the hamlet of Mountain Dale, and surrounding communities in the Neversink River and Rondout Creek drainage basins rely on wells that pump groundwater from valley-fill glacial aquifers for public water supply. Glacial aquifers are vulnerable to contamination because they are...

2022, Scientific Investigations Report 2022-5024
Digital hydrogeologic maps were developed in eight study areas in upstate New York by the U.S. Geological Survey in cooperation with the New York State Department of Environmental Conservation. The digital maps define the hydrogeologic framework of the valley-fill aquifers and surrounding till-covered uplands in the vicinity of the villages...
Areas contributing recharge to selected production wells in unconfined and confined glacial valley-fill aquifers in Chenango River Basin, New York
Paul J. Friesz, John Williams, Jason S. Finkelstein, Joshua Woda
2022, Scientific Investigations Report 2021-5083
In the Chenango River Basin of central New York, unconfined and confined glacial valley-fill aquifers are an important source of drinking-water supplies. The risk of contaminating water withdrawn by wells that tap these aquifers might be reduced if the areas contributing recharge to the wells are delineated and these areas...

The relationships that control seed production in trees are fundamental to understanding the evolution of forest species and their capacity to recover from increasing losses to drought, fire, and harvest. A synthesis of fecundity data from 714 species worldwide allowed us to examine hypotheses that are central to quantifying reproduction,...
Scale-dependent influence of the sagebrush community on genetic connectivity of the sagebrush obligate Gunnison sage-grouse
Shawna J Zimmerman, Cameron L. Aldridge, Mevin B. Hooten, Sara J. Oyler-McCance
2022, Molecular Ecology (31) 3267-3285
Habitat fragmentation and degradation impacts an organism's ability to navigate the landscape, ultimately resulting in decreased gene flow and increased extinction risk. Understanding how landscape composition impacts gene flow (i.e., connectivity) and interacts with scale is essential to conservation decision-making. We used a landscape genetics approach...

• We developed an analytical pipeline supported by web-based infrastructure for integrating continental scale bat monitoring data (stationary acoustic, mobile acoustic, and capture records) to estimate summer (May 1–Aug 31) occupancy probabilities and changes in occupancy over time for 12 North American bat species. This serves as one of multiple...
On the role of climate in monthly baseflow changes across the continental United States
Jessica R. Ayers, Gabriele Villarini, Keith Schilling, Christopher Jones, Andrea E. Brookfield, Samuel Zipper, William H. Farmer
2022, Journal of Hydrologic Engineering (27)
Baseflow is the portion of streamflow that comes from groundwater and subsurface sources. Although baseflow is essential for sustaining streams during low flow and drought periods, we have little information about how and why it has changed over large regions of the continental United States. The objective...

Thomas M. Cronin, Laura Gemery, Baylee M. Olds Olds, Alexa Regnier, Robert Poirier, Sienna Sui
2022, Micropaleontology (68) 233-242
The Arctic Ocean has experienced orbital and millennial-scale climate oscillations over the last 500 kilo-annum (ka) involving massive changes in global sea level and components of the Arctic cryosphere, including sea-ice cover, land-based ice sheets and ice shelves. Although these climate events are only partially understood, micropaleontological studies utilizing...

Aftershocks preferentially occur in previously active areas
Morgan T. Page, Nicholas van der Elst
2022, The Seismic Record (2) 100-106
The clearest statistical signal in aftershock locations is that most aftershocks occur close to their mainshocks. More precisely, aftershocks are triggered at distances following a power‐law decay in distance (Felzer and Brodsky, 2006). This distance decay kernel is used in epidemic‐type aftershock sequence (ETAS) modeling and...
Identifying monitoring information needs that support the management of fish in large rivers
Timothy D. Counihan, Kristen L. Bouska, Shannon K. Brewer, R. B. Jacobson, Andrew F. Casper, Colin G. Chapman, Ian R. Waite, Kenneth R. Sheehan, Mark Pyron, Elise R. Irwin, Karen Riva-Murray, Alexa McKerrow, Jennifer M. Bayer
2022, Environmental Management (17)
Management actions intended to benefit fish in large rivers can directly or indirectly affect multiple ecosystem components. Without consideration of the effects of management on non-target ecosystem components, unintended consequences may limit management efficacy. Monitoring can help clarify the effects of management actions, including on non-target...

David L. George, Richard M. Iverson, Charles M. Cannon
2022, Open-File Report 2021-1118
Large lahars pose substantial threats to people and property downstream from Mount Rainier volcano in Washington State. Geologic evidence indicates that these threats exist even during the absence of volcanic activity and that the threats are highest in the densely populated Puyallup and Nisqually River valleys on the west side...
Invertibility aware integration of static and time-series data: An application to lake temperature modeling
Kshitij Tayal, Xiaowei Jia, Rahul Ghosh, Jared Willard, Jordan Read, Vipin Kumar
2022, Conference Paper, Proceedings of the 2022 SIAM International Conference on Data Mining
Accurate predictions of water temperature are the foundation for many decisions and regulations, with direct impacts on water quality, fishery yields, and power production. Building accurate broad-scale models for lake temperature prediction remains challenging in practice due to the variability in the data distribution across different lake systems monitored by...

Re-evaluating invasive species in degraded ecosystems: A case study of red-eared slider turtles as partial ecological analogs
Marc Dupuis-Desormeaux, Jeffrey E. Lovich, J. Whitfield Gibbons
2022, Discover Sustainability (3)
Exotic species are often vilified as "bad" without consideration of the potential they have for contributing to ecological functions in degraded ecosystems. The red-eared slider turtle (RES) has been disparaged as one of the worst invasive species. Based on this review, we suggest that RES contribute some ecosystem functions in...
