Bayesian calibration of the 40K decay scheme with implications for 40K-based geochronology
Jack N. Carter, Caroline Hasler, Anthony Fuentes, Andrew Tholt, Leah E. Morgan, Paul R. Renne
2025, Geochimica et Cosmochimica Acta
The K/Ar and 40Ar/39Ar geochronometers are based on the naturally occurring radionuclide 40K. Their precision and accuracy are limited by uncertainties on the 40K decay constants and, in the case of the 40Ar/39Ar geochronometer, the isotopic composition of neutron fluence monitors. To address these limitations, we introduce a Bayesian calibration of the 40K decay scheme....

2025, Scientific Data (12)
Moderate-resolution (30-m) national map products have limited capacity to represent fine-scale, heterogeneous urban forms and processes, yet improvements from incorporating higher resolution predictor data remain rare. In this study, we applied random forest models to high-resolution land cover data for 71 U.S. urban areas, moderate-resolution National Land Cover Database (NLCD)...
New paleomagnetic constraints on the eruption timing, stratigraphy, and post-emplacement deformation of the Picture Gorge Basalt within the Columbia River Basalt Group
Anthony Francis Pivarunas, Margaret Susan Avery, Jonathan T. Hagstrum, Scott E.K. Bennett, Andrew T. Calvert
2025, Journal of Geophysical Research: Solid Earth (130)
The Picture Gorge Basalt (PGB) is part of the Miocene Columbia River Basalt Group (CRBG). The PGB, which outcrops in eastern Oregon, is considered coincident in time with the voluminous Grande Ronde Basalt. New radiometric ages have expanded the age‐range of the PGB, suggesting it began erupting prior to the Steens...

We stand at the threshold of a transformative era in Earth observation, marked by space-borne visible-to-shortwave infrared (VSWIR) imaging spectrometers that promise consistent global observations of ecosystem function, phenology, and inter- and intra-annual change. However, the full value of repeat spectroscopy, the information embedded within different temporal scales, and the...
Linking environmental variability to long-term demographic change of an endangered species using integrated population models
Marisa Takada Martinez, Laura D'Acunto, Stephanie Romanach
2025, Journal of Applied Ecology
Understanding how species populations change with environmental conditions is important for implementing effective habitat management and conservation strategies. Challenges to evaluating population-level responses to environmental conditions arise when data are sparse or not spatiotemporally aligned, especially for at-risk species with small, declining numbers.We synthesized 30 years (1992–2021) of three partially...

Rosemary Hartman, Noah Knowles, Amanda Fencl, Julia Ekstrom
2025, San Francisco Estuary and Watershed Science (23)
Droughts are frequent events in the western United States, and can disrupt water supply and degrade water quality, challenging water management in the Sacramento–San Joaquin Delta (Delta).

Science needs for determining the effects of climate change on harmful algal blooms in the southeastern United States
Tom D. Byl, Devin M. Moore, Champagne Cunningham, De’Etra Young
2025, Open-File Report 2025-1004
The Southeastern United States has many lakes, streams, and reservoirs that serve as important drinking water sources with recreational, agricultural, and ecological uses. However, harmful algal blooms (HABs) are becoming more common in these waters, causing health issues for humans and animals. HABs have been listed as a contaminant of...

Wildfires are a rapidly increasing threat to boreal forests. While our understanding of the drivers behind wildfires and their environmental impact is growing, it is mostly limited to the observational period. Here we focus on the boreal forests of southern Siberia and exploit a U–Th-dated stalagmite from Botovskaya Cave, located...

R. Blaine McCleskey, Charles A. Cravotta III, Matthew P. Miller, Tanner William Chapin, Fred D. Tillman, Gabrielle L. Keith
2025, Applied Geochemistry (184)
Salinity levels in streams and tributaries of the Colorado River Basin have been a major concern for the United States and Mexico for over 50 years as the water is used by millions of people for domestic and industrial purposes. Recently, the United States Geological Survey expanded stream monitoring networks...
Deterministic physics-based earthquake sequence simulators match empirical ground-motion models and enable extrapolation to data poor regimes: Application to multifault multimechanism ruptures
Bruce E. Shaw, Kevin Ross Milner, Christine A. Goulet
2025, Seismological Research Letters
We use the deterministic earthquake simulator RSQSim to generate complex sequences of ruptures on fault systems used for hazard assessment. We show that the source motions combined with a wave propagation code create surface ground motions that fall within the range of epistemic uncertainties for the Next Generation Attenuation‐West2 set...
United States Register of Introduced and Invasive Species
Annie Simpson, Mark T. Wiltermuth, Mireya Dorado
2025, Fact Sheet 2024-3037
The pervasive and insidious threat of invasive species costs the United States more than $120 billion, annually. An invasive species is an organism that is not native to a locality and causes (or is likely to cause) harm. An introduced species is one that is nonnative to a locality and...
Designing sortable guilds for multispecies selective fish passage
David Benoit, Daniel Zielinski, Reid G Swanson, Donald Jackson, Robert L. McLaughlin, Theodore Castro-Santos, R. Andrew Goodwin, Thomas C. Pratt, Andrew M. Muir
2025, Fish and Fisheries
The importance of connectivity for freshwater organisms is widely recognised, yet in-stream barriers associated with population declines and increased risk of extinction remain globally ubiquitous. Despite their negative consequences, these barriers can protect aquatic communities by limiting the spread of invasive species, leading to conflicting management goals in some regions....

2025, Open-File Report 2023-1066
IntroductionThe U.S. Air Force (USAF) issued funds to the U.S. Geological Survey (USGS) to update the biosecurity plan, create a current (2019) flora and fauna species identification index, and do container evaluations for the presence of potential invasives. The current (2019) biosecurity protocols used for prevention were evaluated, and new...
A model uncertainty quantification protocol for evaluating the value of observation data
Michael N. Fienen, Laura A. Schachter, Randall J. Hunt
2025, Scientific Investigations Report 2025-5007
The history-matching approach to parameter estimation with models enables a powerful offshoot analysis of data worth—using the uncertainty of a model forecast as a metric for the worth of data. Adding observation data will either have no impact on forecast uncertainty or will reduce it. Removing existing data will either...

Jeffrey M. Lorch, A. Tobin, Alexandria Annelise Argue, Valerie I. Shearn-Bochsler, Brenda M. Berlowski-Zier, Kyle George, Katherine H. Haman, Anne Ballmann
2025, Journal of Wildlife Diseases
The impacts of white-nose syndrome (WNS) on many bat species in eastern North America have been well documented because of the length of time that the causative agent, Pseudogymnoascus destructans (Pd), has been present and the ability to monitor bat hibernacula in that region. However, the disease outcomes for bat species in...

The Perseverance rover is exploring Jezero crater on Mars, one of its goals being to collect samples to be returned to Earth to search for organic remains of ancient Martian life. However, the organic content of these rocks has likely suffered from the radiation environment on the surface of Mars...
Evaluating the potential to quantify salmon habitat via UAS-based particle image velocimetry
Lee R. Harrison, Carl J. Legleiter, Brandon Overstreet, James White
2025, Water Resources Research (3)
Continuous, high-resolution data for characterizing freshwater habitat conditions can support successful management of endangered salmonids. Uncrewed aircraft systems (UAS) make acquiring such fine-scale data along river channels more feasible, but workflows for quantifying reach-scale salmon habitats are lacking. We evaluated the potential for UAS-based mapping of hydraulic habitats using spectrally...

Joshua R. Benton, Daniel H. Doctor
2025, Hydrological Processes (39)
Estimates of dynamic groundwater volumes supplying baseflow to streams are important for water availability projections during extended periods of drought. The primary goals of this study were to provide dynamic storage volume estimates, inferred from streamflow recession analysis, for baseflow regimes within seven gaged catchments within the Neversink Reservoir Watershed...
