2025, Aeolian Research (74)
Aeolian sediment transport shapes landscapes on Earth and other planetary surfaces, yet key uncertainties remain in how the near-bed saltation cloud responds to changing wind and surface conditions. Leveraging recent advances in image-based particle tracking, we conducted wind tunnel experiments using high-speed imaging and Particle Tracking Velocimetry to quantify sand...

Kassidy Frame, Gregory J. Sandland, Charles J. Labuzzetta, Grace L. Loppnow, Jessica C. Stanton, Yu-Chun Kao, Richard A. Erickson
2025, Journal of Wildlife Management (89)
Invasive bigheaded carps (Bighead Carp Hypophthalmichthys nobilis, Silver Carp Hypophthalmichthys molitrix, and their hybrids Hypophthalmichthys spp.) currently infest the Mississippi River Basin. Bigheaded carps can outcompete native species in invaded waters and can also transform the surrounding environment. Currently, resource managers seek to limit the population abundance of bigheaded carps and their range expansion...
An integrated sensor network and data driven approach to satellite remote sensing of dissolved organic matter
Dulcinea Marie Avouris, Erin L Hestir, Jacob Fleck, Jeffrey A. Hansen, Brian A. Bergamaschi
2025, Earth and Space Science (12)
Traditional remote sensing retrieval models for water quality have historically relied on limited, localized data sets due to the prohibitive costs of extensive field campaigns and logistical challenges of collecting match-up data with satellite overpasses. As a result, these models often lack generalizability across seasons, tides, and sites. Furthermore, small...

Sarah Barnes, Robert Al-Chokhachy, Phaedra E. Budy
2025, Transactions of the American Fisheries Society (154) 640-656
ObjectiveLake elevation decline is a global phenomenon with pronounced effects in arid regions that changes the characteristics of nearshore habitat area available to lacustrine spawners, potentially impacting recruitment and whole-lake food web dynamics. Our objective was to understand the potential effects of lake elevation decline on spawning habitat for the...
Grammar to graph—An approach for semantic transformation of annotations to triples
Dalia E. Varanka, Emily Abbott
2025, Scientific Investigations Report 2025-5064
Data annotation is the process of labeling data to show the outcome that a related data model should predict. In this study, annotation data were transformed into semantic graph triples, mainly for use with the Resource Description Framework (RDF), a type of entity-relationship-attribute data model for graph databases. The transformation...

Dawnika L. Blatter, Seth D. Burgess
2025, Journal of Petrology (66)
Clear Lake volcanic field (CLVF) is the northernmost and youngest (~2.2 Ma to 8 ka) of the volcanic centers distributed along the San Andreas transform fault in western California. The initial phase of CLVF volcanism (interval one) occurred between ~2.2 and 1.3 Ma and extends ~35 km southeast of Clear Lake, forming a semi-continuous...

Mohammad Reza M. Behbahani, David M. Rey, Martin A. Briggs, Amvrossios Bagtzoglou
2025, Journal of Hydrology (663)
Seasonal shifts from runoff to groundwater dominance influence daily headwater stream temperatures, especially where local groundwater input is strong. This input buffers temperature during hot periods, supporting cold-water habitats. Recent studies use air–water temperature signal metrics to identify zones of...

Christopher Green, Robert M. Hirsch, Hedeff Essaid, Ward E. Sanford
2025, Science of the Total Environment (999)
Future water availability depends on understanding the responses of constituent concentrations to hydrologic change. Projecting future water quality remains a methodological challenge, particularly when using discrete observations with limited temporal resolution. This study introduces Weighted Regression on Time, Discharge, and Season for Projection (WRTDS-P), a novel, computationally efficient method that...

Rosemary M. Fanelli, Michelle Morency, Brandon J. Fleming, Joel Moore, Deanna Hardesty, Megan E. Shoda
2025, Environmental Monitoring and Assessment
Rising chloride concentrations pose critical risks to freshwater stream ecosystems in temperate regions like the Delaware River Basin (DRB), USA, where winter deicer applications (i.e., road salt) are common. Increasing chloride concentrations have been documented in the region, but the extent to which chloride exceeds regulatory benchmarks remains unclear because...

Sean Alois Lewandoski, Christopher M. Holbrook
2025, Canadian Journal of Fisheries and Aquatic Sciences (82) 1-13
Invasive sea lamprey inhabiting the North American Laurentian Great Lakes are the target of the world’s longest running vertebrate invasive species control program. However, metapopulation dynamics comprising survival and dispersal during the sea lampreys’ lake-resident life stages are poorly understood. We applied acoustic telemetry and continuous-time multistate capture-recapture modeling to...
