2023, Scientific Reports (13)
Impacts of sea level rise will last for centuries; therefore, flood risk modeling must transition from identifying risky locations to assessing how populations can best cope. We present the first spatially interactive (i.e., what happens at one location affects another) land change model (FUTURES 3.0) that can probabilistically predict urban...
Importance of understanding bottom-up control when characterizing geothermal systems
Jared R. Peacock, Paul A. Bedrosian
2023, Conference Paper, Using the Earth to save the Earth (GRC transactions)
Methods designed to identify favorable areas for geothermal resources have traditionally been focused on near-surface information, namely data that can be compiled into a 2D map. However, these methods fail to account for the third dimension: depth. As a result, they do not incorporate deep crustal and mantle features like...
Geophysical logging For hydrogeology
John Williams, Frederick L. Paillet
2023, Book
Geophysical logging is the measurement and analysis of electrical, acoustic, nuclear, and other physical properties in a borehole using wireline or direct push technology. Geophysical logging is one of the primary methods of collecting subsurface information for hydrogeologic investigations. Groundwater scientists and engineers should have a basic understanding of borehole geophysics...

Shane Nichols-O’Neill, Jorge Lorenzo-Trueba, Daniel J. Ciarletta, Jennifer L. Miselis
2023, Conference Paper, The Proceedings of the Coastal Sediments 2023
This study aims to identify the natural processes and the subsequent responses to coastal engineering and development on the alongshore evolution of the IB-BI-LBI inlet-barrier system. The primary focus will be the quantification of barrier island and inlet sediment partitioning at decadal to centennial timescales, from 1839-1941. We analyze historical...
Vital sign monitoring is good medicine for parks
Andrew M. Ray, David P. Thoma, Kristin L. Legg, Robert H. Diehl, Adam Sepulveda, Mike Tercek, Robert Al-Chokhachy
2023, Yellowstone Science
Nearly 70 years ago a young ranger naturalist working in Yellowstone National Park (YNP), Frederick B. Turner, became fascinated with the abundance of frogs next to his cabin at “Soldier Creek” (known as Lodge Creek today). This interest blossomed into Turner’s PhD research and his publication in 1960 about the...

2023, Ecological Informatics (77)
Remote cameras (“trail cameras”) are a popular tool for non-invasive, continuous wildlife monitoring, and as they become more prevalent in wildlife research, machine learning (ML) is increasingly used to automate or accelerate the labor-intensive process of labelling (i.e., tagging) photos. Human-machine hybrid tagging approaches have been shown to greatly increase...

Emily T. Richardson, Angela Hansen, Tamara E. C. Kraus, Bryan D. Downing, Don Forsberg, John Stillian, Katy O’Donnell, Crystal Lee Sturgeon, Brian A. Bergamaschi
2023, Limnology and Oceanography Methods (21) 761-774
Documenting dissolved inorganic nitrogen (DIN) concentration and form at appropriate temporal and spatial scales is key to understanding aquatic ecosystem health, particularly as DIN fuels primary productivity. In addition to point and non-point source nutrient inputs, factors such as hydrology, geomorphology, temperature, light, and biogeochemical transformations influence nutrient dynamics in...

Grant Harold Rea-Downing, Claire Bouligand, Jonathan M.G. Glen, Tait E. Earney, Laurie A. Zielinski, Jacob Elliott Anderson, Peter J. Kelly
2023, Conference Paper, 2023 Summit on Drone Geophysics program book
Small Uncrewed Aerial Systems (sUAS) serve as critical platforms for geophysical data collection at an intermediate scale between lower resolution, regional datasets collected via crewed aerial surveys, and high resolution, but spatially sparse sampling of ground-based data collection methods. Advances in sensor design and sUAS capabilities have led to rapid...

The U.S. Geological Survey (USGS) Risk Research and Applications Community of Practice (Risk CoP) is a bureau-wide forum to share resources and discuss issues relevant to “conducting and applying scientific research in hazards—the dangerous processes or phenomena that may cause damage—to enhance the reduction of risk—the potential for societally relevant...
Decadal shifts in the population growth, regeneration, and health of Taxodium distichum in swamps of the Cache River Watershed, Illinois
Beth Middleton, Darren Johnson
2023, Journal for Nature Conservation (76)
Population projection models based on long-term trends in regeneration and tree survival can be used to predict the future stability of swamp forest species using water management. Population growth and regeneration of a foundational tree species in North American cypress swamps (Taxodium distichum) were compared...
Trade-offs in adapting to changes in climate, land use, and water availability in California
Nathan D. Van Schmidt, Tamara Wilson, Lorraine E. Flint, R. Langridge
2023, Ecology and Society (28)
Changes in land use and land cover, water systems, and climate are inextricably linked, and their combined stresses have had severe impacts in many regions worldwide. Integrated adaptation planning can support adaptive capacity by helping institutions manage land and water resources at regional to local scales. Linkages between these stressors...

2023, Geochimica et Cosmochimica Acta (362) 77-103
An accepted paradigm of hydrothermal systems is the process of phase separation, or boiling, of a deep, homogeneous hydrothermal fluid as it ascends through the subsurface resulting in gas rich and gas poor fluids. While phase separation helps to explain first-order patterns in the chemistry and biology of a hot...

2023, Ecological Indicators (156)
Updating predictions of the response of high-profile, at-risk species to climate change and anthropogenic stressors is vital for informing effective conservation action. Here, we review two prior generations of Bayesian network probability models predicting changes in global polar bear (Ursus maritimus) population status, and provide...

Jeremy S. Littell, Gregory T. Pederson, Justin T. Martin, Stephen T. Gray
2023, Water Resources Research (59)
Water resources in the Pacific Northwest (PNW) are characterized by significant interannual to interdecadal variation. Paleo-proxy reconstructions such as those derived from tree-rings provide longer-term context and supplement information on this expected range of variability, which can improve planning, management, and response related to extreme events and...

2023, Environmental Science and Technology (57) 17511-17521
Mercury (Hg) is a toxic contaminant that has been mobilized and distributed worldwide and is a threat to many wildlife species. Amphibians are facing unprecedented global declines due to many threats including contaminants. While the biphasic life history of many amphibians creates a potential nexus for methylmercury (MeHg) exposure in...
Stream hydrology and a pulse subsidy shape patterns of fish foraging
Kevin Fitzgerald, J. Ryan Bellmore, Jason B. Fellman, Matthew L. H. Cheng, Claire Delbecq, Jeffrey A. Falke
2023, Journal of Animal Ecology (92) 2386-2398
Pulsed subsidy events create ephemeral fluxes of hyper-abundant resources that can shape annual patterns of consumption and growth for recipient consumers. However, environmental conditions strongly affect local resource availability for much of the year, and can heavily impact consumer foraging and growth patterns prior to pulsed subsidy events. Thus,...

Dating the penultimate great earthquake in south-central Alaska using tree-ring crossdating and radiocarbon wiggle-matching
David J Barclay, Peter J. Haeussler, Robert C. Witter
2023, Quaternary Science Advances (13)
A forest bed of tree stumps currently in the intertidal zone at Girdwood, south-central Alaska, records coseismic submergence during the penultimate great earthquake. Tree-ring samples from ten spruce stumps were crossdated to develop a 149-year-long ring-width chronology. Radiocarbon wiggle-matching found that single-ring ages from the chronology were offset 28 ± 7 years older...

Lori M. Pigue, Kristen A. Bennett, Briony H.N. Horgan, Lisa Gaddis
2023, Journal of Geophysical Research: Planets (128)
Lunar Pyroclastic Deposits (LPDs) are sites of explosive volcanism and often occur in areas of effusive volcanism on the Moon. On Earth, it has been observed that most volcanism has both effusive and explosive phases, whereas on the Moon, these two types of volcanism have typically been...
