Synthesizing binational data to characterize shared water resources is critical to informing binational management. This work uses binational hydrogeology and water resource data in the Mesilla/Conejos-Médanos Basin (Basin) to describe the hydrologic conceptual model and identify potential research that could help inform sustainable management. The Basin aquifer...
Tectonostratigraphy and major structures of the Georgian Greater Caucasus: Implications for structural architecture, along-strike continuity, and orogen evolution
Charles Cashman Trexler, Eric Cowgill, Nathan A Niemi, Dylan A Vasey, Tea Godoladze
2022, Geosphere (18) 211-240
Although the Greater Caucasus Mountains have played a central role in absorbing late Cenozoic convergence between the Arabian and Eurasian plates, the orogenic architecture and the ways in which it accommodates modern shortening remain debated. Here, we addressed this problem using geologic mapping along...
Coastal paleogeography of the Pacific Northwest, USA, for the last 12,000 years accounting for three-dimensional earth structure
Jorie Clark, Jay R. Alder, Marisa Borreggine, Jerry X Mitrovica, Konstantin Latychev
2022, Quaternary International (638-639) 197-204
Predictive modeling of submerged archaeological sites requires accurate sea-level predictions in order to reconstruct coastal paleogeography and associated geographic features that may have influenced the locations of occupation sites such as rivers and embayments. Earlier reconstructions of the paleogeography of parts of the western U.S. coast used an...

Kellan R. Strauch, Philip J. Soenksen
2022, Scientific Investigations Report 2021-5102
The Niobrara River of northern Nebraska is a valuable water resource that sustains irrigated agriculture and recreation, as well as a diverse ecosystem. Large-quantity withdrawals from the source aquifer system have the potential to reduce the flow into the river and to adversely affect the free-flowing condition of the Niobrara...

L.J. Schilder, L.J. Heintzman, N.E. Mcintyre, S. Harryman, C.A. Hagen, R. E. Martin, Clint W. Boal, Blake A. Grisham
2022, Journal of Wildlife Management (86)
The lesser prairie-chicken (Tympanuchus pallidicinctus) is a species of conservation concern on the Southern High Plains of Texas and New Mexico, USA. Because fragmentation and isolation have increased since pre-settlement, dispersal through this heterogeneous landscape may be constrained, with serious implications for conservation and management of this species. Our objectives...

Contributing areas to domestic wells in dipping sedimentary rocks under extreme recharge events
Claire R. Tiedeman, Allen M. Shapiro
2022, Groundwater (60) 460-476
We use particle tracking to determine contributing areas (CAs) to wells for transient flow models that simulate cyclic domestic pumping and extreme recharge events in a small synthetic watershed underlain by dipping sedimentary rocks. The CAs consist of strike-oriented bands at locations where the water table intersects high-hydraulic conductivity beds,...

Alynn Martin, John T. Hogg, Kezia R. Manlove, Tayler N LaSharr, Justin M. Shannon, Douglas E. McWhirter, Hollie Miyasaki, Kevin L. Monteith, Paul C. Cross
2022, Journal of Wildlife Management (86)
Secondary sexual traits (e.g., horns and antlers) have ecological and evolutionary importance and are of management interest for game species. Yet, how these traits respond to emerging threats like infectious disease remains underexplored. Infectious pneumonia threatens bighorn sheep (Ovis canadensis) populations across North America and we...

Weakly supervised spatial deep learning for Earth image segmentation based on imperfect polyline labels
Zhe Jiang, Wenchong He, M. S. Kirby, Arpan Man Sainju, Shaowen Wang, Larry Stanislawski, Ethan J. Shavers, E. Lynn Usery
2022, ACM Transactions on Intelligent Systems and Technology (13)
In recent years, deep learning has achieved tremendous success in image segmentation for computer vision applications. The performance of these models heavily relies on the availability of large-scale high-quality training labels (e.g., PASCAL VOC 2012). Unfortunately, such large-scale high-quality training data are...

2022, Conservation Genetics (23) 341-357
Throughout their range, Brook Trout (Salvelinus fontinalis) occupy thousands of disjunct drainages with varying levels of disturbance, which presents substantial challenges for conservation. Within the southern Appalachian Mountains, fragmentation and genetic drift have been identified as key threats to the genetic diversity of the Brook Trout...
Late Jurassic-Early Cretaceous orogenic gold mineralization in the Klamath Mountains, California: Constraints from 40Ar/39Ar dating of hydrothermal muscovite
Ryan D. Taylor, Leah E. Morgan, Fred Jourdan, Thomas Monecke, Erin E. Marsh, Richard J. Goldfarb
2022, Ore Geology Reviews (141)
The Klamath Mountains gold province is the second most important historical producer in California, having produced more than 7 Moz of gold from both lode and placer sources. Hydrothermal muscovite grains from gold-bearing veins provide the first 40Ar/39Ar age constraints indicative of a protracted period...

Benjamin Choat, Amber Pulido, Aditi S. Bhaskar, Rebecca Hale, Harry X. Zhang, Thomas Meixner, Lauren McPhillips, Kristina G. Hopkins, Jennifer Cherrier, Chingwen Cheng
2022, Journal of Sustainable Water in the Built Environment (8) 1-10
Urban stormwater is an ongoing contributor to the degradation of the health of many watersheds and water bodies. In the United States, federal regulations (e.g., Clean Water Act) require monitoring and reporting of relevant water quality metrics in regulated waterbodies to ensure standards are being met, but decisions about how...
A web-based tool for assessing the condition of benthic diatom assemblages in streams and rivers of the conterminous United States
Daren M. Carlisle, Sarah Spaulding, Meredith Tyree, Nicholas O. Schulte, Sylvia S Lee, Richard M. Mitchell, Amina A. Pollard
2022, Ecological Indicators (135)
Benthic diatom assemblages are known to be indicative of water quality but have yet to be widely adopted in biological assessments in the United States due to several limitations. Our goal was to address some of these limitations by developing regional multi-metric indices (MMIs) that are robust to inter-laboratory taxonomic...
