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...

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...

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...

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...

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,...
Relationship between explosive and effusive volcanism in the Montes Apenninus region of the Moon

Effect of feeding history on metabolic rate of largemouth bass (Micropterus nigricans): implications for bioenergetics models
Steven H. Ranney, Steven R. Chipps, David H. Wahl
2023, Canadian Journal of Zoology (102) 207-216
Metabolic rate is a key parameter in fish energy budgets that strongly influences the output of bioenergetics models. In this study, we tested the hypothesis that metabolic rate varies with growth history of age-1 largemouth bass Micropterus nigricans Cuvier, 1828. Two groups of fish were fed alternating maintenance or ad libitum rations...

Samuel Adam Miller, James S. Webber, John D. Jastram, Marcus F Aguilar
2023, Environmental Monitoring and Assessment (195)
Excess sediment is a common reason water bodies in the USA become listed as impaired resulting in total maximum daily loads (TMDL) that require municipalities to invest millions of dollars annually on management practices aimed at reducing suspended-sediment loads (SSLs), yet monitoring data are rarely used...
