Approximate inland extent of saltwater intrusion at the base of the Biscayne aquifer, Miami-Dade County, Florida, 2022
Jade Ziqiu Zhang, Corinne Renshaw
2025, Scientific Investigations Map 3541
Miami-Dade County is part of a densely populated urban corridor in southeastern Florida. The Biscayne aquifer serves as Miami-Dade County’s primary drinking water source and is characterized by highly permeable karstic limestone and carbonate sand. The aquifer’s coastal location and permeable nature make it susceptible to saltwater intrusion. Monitoring the...

2025, JAWRA Journal of the American Water Resources Association (61)
The U.S. Geological Survey is developing nationally consistent water-use modeling approaches to replace previous methods relying on locally specific reported and estimated data. These national assessments require datasets that incorporate water withdrawal variability across the United States and over long periods. However, source data often have unclear definitions, missing or...

2025, Ecological Applications (35)
Integration of agroecosystems and other working landscapes with protected lands and waters is critical to the conservation of Earth's biodiversity. Rice agroecosystems support many species by providing aquatic habitat where natural wetlands have been altered or drained. In regions with long dry seasons, rice fields and associated irrigation canals provide...

2025, North American Journal of Fisheries Management (45) 1211-1219
ObjectiveWhite Catfish Ameiurus catus has been introduced to coastal watersheds across the United States. In the Penobscot River, Maine, this species has become increasingly common in upstream habitats that have been made accessible by recent dam removals. We characterized the movements of White Catfish to understand the temporal...
Predicting sediment bulk density for San Francisco Estuary
Samantha C. McGill, Jessica R. Lacy
2025, San Francisco Estuary and Watershed Science (23)
Sediment bulk density (ρ-dry) and particle size are two important parameters for predicting sediment bed erosion. ρ-dry, however, is difficult to measure accurately. The units of ρdry have not been consistently reported in the literature, leading to confusion, particularly in the calculation of sediment budgets that typically require integrating mass-based...

Keith Bouma-Gregson, Lisa Lucas, Andrea Cecile Jaegge, Dulcinea Marie Avouris, Emily T. Richardson, Jacob Aaron Zwart, Tamara E. C. Kraus
2025, Preprint
Cyanobacterial harmful algal blooms (CHABs) are a growing concern in freshwater environments. These blooms can lead to degraded water quality, ecosystem disruptions, and public health threats due to the production of potent cyanotoxins. The Sacramento–San Joaquin Delta (California, USA; the Delta) has experienced CHABs since 1999, including CHABs that produce...

2025, Environmental Research Letters (20)
Spatio-temporal changes to our world’s surface water resources are escalating. Translating how these changes impact communities and ecosystems requires time-varying data of Global Surface Water Extents (GSWE). Traditionally, GSWE mapping has been limited to static estimates, with recent efforts focusing on annual averages, frequency and occurrence of...

River ice controls permafrost bank erosion across an Arctic delta
J Arcuri, Irina Overeem, Marisa Repasch, R. S. Anderson, S. P. Anderson, Joshua C. Koch, Frank Urban
2025, Earth Surface Processes and Landforms (50)
Bank erosion in Arctic rivers helps shape channel geometry, mobilizes carbon from permafrost and influences sediment delivery to the Arctic Ocean. On Alaska's Arctic coastal plain, rivers begin flowing during snowmelt in late spring while extensive river ice persists in channels, such that hydraulics are altered and water is kept...

2025, Geoscientific Model Development (18) 9319-9348
Models of coastal barrier geomorphic and ecologic change are valuable tools for understanding and predicting when, where, and how barriers evolve and transition between ecogeomorphic states. Few existing models of barrier systems are designed to operate over spatiotemporal scales congruous with effective management practices (i.e., decades/kilometers, referred to herein as...

2025, Journal of Great Lakes Research (51)
Lake whitefish (Coregonus clupeaformis) populations in the upper Great Lakes have undergone declines in the past two decades, particularly in Lakes Michigan and Huron. However, cisco (Coregonus artedi) are recovering in parts of the Great Lakes. Population declines are hypothesized to be due, in part, to reduced zooplankton prey in...

Estimation of dynamic geologic CO2 storage resources in the Illinois Basin, including effects of brine extraction, anisotropy, and hydrogeologic heterogeneity
Michelle R. Plampin, Steven T. Anderson, Stefan Finsterle, Ashton M. Wiens
2025, Frontiers in Earth Science (13)
Since the vast majority of carbon dioxide (CO2) storage resources in the United States are in deep saline aquifers, optimizing the use of these saline storage resources could be crucial for efficient development of geologic CO2 storage (GCS) resources and basin- or larger-scale deployment of GCS in the country. Maximum CO2 injection...
Detecting hidden sedimentary geothermal systems in the Upper Colorado River Basin
Rand Gardner, Justin E. Birdwell, Donald S. Sweetkind, Patrick Sullivan, Melia Eaton, Holger Petermann, Annaka Clement, James Hagadorn, Joshua Woda
2025, Conference Paper, Using the Earth to save the Earth
Geothermal resources exist in sedimentary rock where circulation of water for efficient extraction or storage of heat is possible. Except in rare instances where hot water is expressed at the land surface, sedimentary geothermal resources are hidden, so the identification of these systems is optimally accomplished using predictive subsurface modeling....
