2023, Ocean Engineering (284)
Living shorelines gain increasing attention because they stabilize shorelines and reduce erosion. This study leverages physics-based models and bagged regression tree (BRT) machine learning algorithm to simulate wave dynamics at a living shoreline composed of constructed oyster reefs (CORs) in upper Delaware Bay. The physics-based models consist of coupled Delft3D-FLOW and SWAN in four-level...

2023, Journal of Volcanology and Geothermal Research (439)
The VEI 6, Tierra Blanca Joven pyroclastic sequence (30–90 km3 DRE volume), erupted from Ilopango caldera, El Salvador, in 431 CE, is the product of one of the largest eruptions of the last two millennia. The eruption devastated Central America's Mayan civilization. The...
Percent-slope map showing historical anthracite coal-mining infrastructure at the northern end of the Lackawanna syncline, Wayne, Susquehanna, and Lackawanna Counties, Pennsylvania
Gregory J. Walsh, Mark C. Walsh
2023, Scientific Investigations Map 3507
Introduction Abandoned railroads and infrastructure from the anthracite coal-mining industry are significant features in abandoned mine lands and are an important part of history; however, these features are often lost and masked by the passage of time and the regrowth of forests. The application of modern light detection and ranging (lidar)...

Pamela E. Michael, Kathy M. Hixson, Jeffery S. Gleason, Christopher Haney, Yvan Satgé, Patrick G.R. Jodice
2023, PLoS ONE (18)
The Gulf of Mexico supports many seabird species, yet data gaps describing species composition and habitat use are prevalent. We used vessel-based observations from the Gulf of Mexico Marine Assessment Program for Protected Species to identify and characterize distinct seabird assemblages in the northern Gulf of...

2023, Environment International (178)
Drinking-water quality is a rising concern in the United States (US), emphasizing the need to broadly assess exposures and potential health effects at the point-of-use. Drinking-water exposures to per- and poly-fluoroalkyl substances (PFAS) are a national concern, however, there is limited information on PFAS in residential tapwater at the point-of-use,...

The environments of Arctic Ocean nearshore areas experience high intra- and inter-annual variability, making it difficult to evaluate the impact of anthropogenic warming. However, a sediment record from the southern Canadian Beaufort Sea allowed us to reconstruct the impacts of climate and environmental changes over the last 1300 years along the northern Yukon...

Bernard E. Hubbard, Tanya J. Gallegos, Victoria G. Stengel
2023, MDPI-Minerals (13)
Worldview-3 (WV3) 16-band multispectral data were used to map exposed bedrock and mine waste piles associated with legacy open-pit mining of sandstone-hosted roll-front uranium deposits along the South Texas Coastal Plain. We used the “spectral hourglass” approach to extract spectral endmembers representative of these features from the image. This...

Evan Um, Michael Commer, Roland Gritto, Jared R. Peacock, David Alumbaugh, Steve P. Jarpe, Craig Hartline
2023, Geophysics (88) WB45-WB54
The Geysers geothermal field located in northern California, USA, is the world’s largest electricity-generating geothermal facility. To delineate the spatio-temporal distribution of reservoir steam and recharge water, we have collected microseismic and magnetotelluric (MT) data using a dense array of stations in 2021. The microseismic and MT data have been...

2023, Scientific Investigations Report 2023-5036
Water resources in the coastal region of North Carolina and South Carolina (Coastal Carolinas) are currently under stress from competing ecological and societal needs. Projected changes in climate and population are expected to place even more stress on water resources in the region. The Coastal Carolinas Focus Area Study...
Wetland management practices and secretive marsh bird habitat in the Mississippi Flyway: A review
Kristen M. Malone, Elisabeth B. Webb, Doreen C. Mengel, Laura Kearns, Ann E. McKellar, Sumner W. Matteson, Benjamin R. Williams
2023, The Journal of Wildlife Management (87)
Management regimes on publicly owned freshwater wetlands in the Mississippi Flyway of North America (i.e., Flyway) have historically emphasized waterfowl, but there is limited information on how waterfowl-focused wetland management affects other wetland-dependent wildlife. Secretive marsh birds (SMBs) depend on wetlands with emergent vegetation...
Pollinator conservation and climate science at the U.S. Geological Survey
Elise R. Irwin, Jonathan R. Mawdsley
2023, Fact Sheet 2023-3026
Introduction Ecosystems—whether agricultural, urban, or natural—depend on pollinators, great and small. Pollinators in the form of bees, birds, butterflies, bats, and even moths provide vital, but often invisible services, from contributing to biodiverse terrestrial wildlife and plant communities to supporting healthy watersheds. Pollinator declines worldwide have been noted as land-use and...
Ensemble estimation of historical evapotranspiration for the conterminous U.S.
Meredith Reitz, Ward E. Sanford, Samuel Saxe
2023, Water Resources Research (59)
Evapotranspiration (ET) is the largest component of the water budget, accounting for the majority of the water available from precipitation. ET is challenging to quantify because of the uncertainties associated with the many ET equations currently in use, and because observations of ET are uncertain and sparse....
The influence of vegetated marshes on wave transformation in sheltered estuaries
Rae M. Taylor-Burns, Cornelis M. Nederhoff, Jessica R. Lacy, Patrick L. Barnard
2023, Coastal Engineering (184)
Assessing the influence of marshes on mitigating flooding along estuarine shorelines under the pressures of sea level rise requires understanding wave transformation across the marsh. A numerical model was applied to investigate how vegetated marshes influence wave transformation. XBeach non-hydrostatic (XB-NH) was calibrated and validated with...

2023, Geophysical Research Letters (50)
On 15 January 2022, Hunga Volcano in Tonga produced the most violent eruption in the modern satellite era, sending a water-rich plume at least 58 km high. Using a combination of satellite- and ground-based sensors, we investigate the astonishing rate of volcanic lightning (>2,600 flashes min−1) and what...
Hydrogeomorphic changes along mid-Atlantic coastal plain rivers transitioning from non-tidal to tidal: Implications for a rising sea level
Daniel Kroes, Gregory E. Noe, Cliff R. Hupp, Thomas Rossiter Doody, P.A. Bukaveckas
2023, Estuaries and Coasts (46) 1438-1458
Sea level rise is affecting reaches of coastal rivers by increasing water levels and propagating tides inland. The transition of river systems into tidal estuaries has been neglected in hydrogeomorphic studies. A better understanding of transitioning reaches is critical to understanding ecosystem dynamics, services, and developing predictive capabilities of change...
Land development and road salt usage drive long-term changes in major-ion chemistry of streamwater in six exurban and suburban watersheds, southeastern Pennsylvania, 1999-2019
Marissa Lee Rossi, Peleg Kremer, Charles A. Cravotta III, Krista E. Seng, Steven T. Goldsmith
2023, Frontiers in Environmental Science (11)
In urbanized areas, the “freshwater salinization syndrome” (FSS), which pertains to long-term increases in concentrations of major ions and metals in fresh surface waters, has been attributed to road salt application. In addition to FSS, the water composition changes as an influx of sodium (Na+) in recharge may displace calcium...
