Donald S. Sweetkind, Kristine L. Zellman
2023, Data Report 1183
A database of spatial footprints and characteristics of three-dimensional geological models that were constructed by the U.S. Geological Survey between 2004 and 2022 was compiled as part of ongoing development of subsurface geologic information by the USGS National Cooperative Geologic Mapping Program. This initial inventory resulted in the compilation of...
Hidden system identification: Basin modeling as a tool for examining sedimentary geothermal resource potential
Rand Gardner, Justin E. Birdwell
2023, Conference Paper, Using the Earth to save the Earth
Three-dimensional (3D) geologic and temperature models have been developed for the onshore U.S. Gulf Coast. The results from these models identify areas of moderate- to high-temperature (90°-150°C and >150°C; respectively) geothermal resources at depths <6 km. This modeling study addresses the fundamental challenge of predicting where opportune temperature and lithology...

Lillian G. Smith, Daniel H. Doctor, Cheyenne L. Cox
2023, Conference Paper, Proceedings of the 17th multidisciplinary conference on sinkholes and the engineering and environmental impacts of karst
Identifying and analyzing closed depressions in karst areas is important for sinkhole hazard evaluation and land management. We created a sinkhole inventory in the karst region of northwest Puerto Rico using a lidar-derived elevation model acquired in 2018 approximately eleven months after Hurricane Maria. The goal of this project is...
Red Knot stopover population size and migration ecology at Delaware Bay, USA, 2023
James E. Lyons
2023, Report
Red Knots (Calidris canutus rufa) stop at Delaware Bay on the mid-Atlantic coast of North America during northward migration to feed on eggs of horseshoe crabs (Limulus polyphemus). We conducted a mark-recapture-resight investigation to estimate the passage population of Red Knots at Delaware Bay in 2023. We used a Bayesian...
Examining current bias and future projection consistency of globally downscaled climate projections commonly used in climate impact studies
Lucas Berio Fortini, Lauren R. Kaiser, Abby G. Frazier, Thomas W Giambelluca
2023, Climatic Change (176) 169
The associated uncertainties of future climate projections are one of the biggest obstacles to overcome in studies exploring the potential regional impacts of future climate shifts. In remote and climatically complex regions, the limited number of available downscaled projections may not provide an accurate representation of...

2023, Journal of Fish and Wildlife Management (14) 385-399
The accuracy of posttranslocation population monitoring methods is critical to assessing long-term success in translocation programs. Translocation can produce unique challenges to monitoring efforts; therefore, it is important to understand the flexibility and robustness of commonly used monitoring methods. In Florida, USA, thousands of gopher tortoises Gopherus polyphemus have been, and continue...

A simple approach to modeling light attenuation in the Sacramento-San Joaquin Delta using commonly available data
Emily T. Richardson, Keith Bouma-Gregson, Katy O’Donnell, Brian A. Bergamaschi
2023, San Francisco Estuary and Watershed Sciences (21)
The diffuse attenuation coefficient of photosynthetically active radiation (KdPAR) is commonly used to predict light attenuation in aquatic productivity models, but obtaining measurements of PAR to compute KdPAR is difficult. In situ calculations of KdPAR require multiple measurements of PAR through the...

Haleakalā National Park and montane areas on east Maui, Hawaiian Archipelago, support critical nesting habitat for endangered ‘ua‘u Hawaiian petrel Pterodroma sandwichensis. Habitat loss, non-native predators, and damage by feral ungulates are limiting factors for ground-nesting petrels at Haleakalā and throughout Hawai‘i. Because nesting habitats differ among the Hawaiian Islands,...

2023, Wetlands (43)
Wetlands cover a small portion of the world, but have disproportionate influence on global carbon (C) sequestration, carbon dioxide and methane emissions, and aquatic C fluxes. However, the underlying biogeochemical processes that affect wetland C pools and fluxes are complex and dynamic, making measurements of wetland C challenging. Over decades...

Northern high-latitude lakes are critical sites for carbon processing and serve as potential conduits for the emission of permafrost-derived carbon and greenhouse gases. However, the fate and emission pathways of permafrost carbon in these systems remain uncertain. Here, we used the natural abundance of radiocarbon to identify and trace the...
Where the past meets the present: Connecting nitrogen from watersheds to streams through groundwater flowpaths
Eric M. Moore, Janet R. Barclay, Adam B. Haynes, Kevin E. Jackson, Alaina M. Bisson, Martin A. Briggs, Ashley M. Helton
2023, Environmental Research Letters (18)
Groundwater discharge to streams is a nonpoint source of nitrogen (N) that confounds N mitigation efforts and represents a significant portion of the annual N loading to watersheds. However, we lack an understanding of where and how much groundwater N enters streams and watersheds. Nitrogen concentrations at...

Jong Cho, Diana Karwan, Katherine Skalak, James Pizzuto, Max Huffman
2023, Frontiers in Water (5)
Sediment connectivity is a conceptualization for the transfer and storage of sediment among different geomorphic compartments across upland landscapes and channel networks. Sediment connectivity and dysconnectivity are linked to the water cycle and hydrologic systems with the associated multiscale interactions with climate, soil, topography, ecology, and landuse/landcover under natural...
