The Cross-Hosgri slope is a bathymetric lineament that crosses the main strand of the Hosgri fault offshore Point Estero, central California. Recently collected chirp seismic reflection profiles and sediment cores provide the basis for a reassessment of Cross-Hosgri slope origin and the lateral...
Foundations of modeling resilience of tidal saline wetlands to sea-level rise along the U.S. Pacific Coast
Bruce G. Marcot, Karen M. Thorne, Joel A. Carr, Glenn R. Guntenspergen
2023, Landscape Ecology
Context Tidal saline wetlands (TSWs) are highly threatened from climate-change effects of sea-level rise. Studies of TSWs along the East Coast U.S. and elsewhere suggest significant likely losses over coming decades but needed are analytic tools gauged to Pacific Coast U.S. wetlands.Objectives We predict the impacts of sea-level rise (SLR)...

Increasing ocean wave energy observed in Earth’s seismic wavefield since the late 20th century
Richard C. Aster, Adam T. Ringler, Robert E. Anthony, Thomas A. Lee
2023, Nature Communications (14)
Ocean waves excite continuous globally observable seismic signals. We use data from 52 globally distributed seismographs to analyze the vertical component primary microseism wavefield at 14–20 s period between the late 1980s and August 2022. This signal is principally composed of Rayleigh waves generated by ocean wave seafloor tractions at...
Spatially interactive modeling of land change identifies location-specific adaptations most likely to lower future flood risk
Georgina M. Sanchez, Anna Petrasova, Megan M. Skrip, Elyssa Collins, Margaret A. Lawrimore, John B. Vogler, Adam Terando, Jelena Vukomanovic, Helena Mitasova, Ross K. Meentemeyer
2023, Scientific Reports (13)
Impacts of sea level rise will last for centuries; therefore, flood risk modeling must transition from identifying risky locations to assessing how populations can best cope. We present the first spatially interactive (i.e., what happens at one location affects another) land change model (FUTURES 3.0) that can probabilistically predict urban...
Exploring centennial barrier-inlet evolution: Insights from undeveloped and developed phases at Barnegat Inlet, New Jersey
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...
Incorporating wave climate complexity into modeling lower shoreface morphology and transport
Megan N. Gillen, Andrew D. Ashton, Jennifer L. Miselis, Daniel J. Ciarletta, Emily A. Wei, Christopher R. Sherwood
2023, Conference Paper, The Proceedings of Coastal Sediments 2023
The lower shoreface, a transitional subaqueous region extending from the seaward limit of the surf zone to beyond the closure depth, serves as a sediment reservoir and pathway in sandy beach environments over annual to millennial time scales. Despite the important role this region plays in shoreline dynamics, the morphodynamics...
Reconstructing the geomorphic evolution and sediment budget history of a dynamic barrier island: Anclote Key, Florida
Daniel J. Ciarletta, Jennifer L. Miselis, Julie Bernier, Arnell S. Forde, Shannon A. Mahan
2023, Conference Paper, The Proceedings of the Coastal Sediments 2023
Decadal to centennial variations in sediment availability are a primary driver of coastal change within barrier systems. Models help explore how barrier morphology relates to past changes in magnitude of sediment availability, but this requires insights and validation from field efforts. In this study, we investigate the progradation of Anclote...
Increasing salt marsh elevation using sediment augmentation: Critical insights from surface sediments and sediment cores
Elizabeth Fard, Lauren N. Brown, Richard F. Ambrose, Christine R Whitcraft, Karen M. Thorne, Nathaniel J. Kemnitz, Douglas E. Hammond, Glen M. MacDonald
2023, Environmental Management
Sea-level rise is particularly concerning for tidal wetlands that reside within an area with steep topography or are constrained by human development and alteration of sedimentation. Sediment augmentation to increase wetland elevations has been considered as a potential strategy for such areas to prevent wetland loss...

Emily Teresa Richardson, Angela Hansen, Tamara E. C. Kraus, Bryan D. Downing, Don Forsberg, John Stillian, Katy O'Donnell, Crystal Lee Sturgeon, Brian A. Bergamaschi
2023, Limnology and Oceanography Methods
Documenting dissolved inorganic nitrogen (DIN) concentration and form at appropriate temporal and spatial scales is key to understanding aquatic ecosystem health, particularly as DIN fuels primary productivity. In addition to point and non-point source nutrient inputs, factors such as hydrology, geomorphology, temperature, light, and biogeochemical transformations influence nutrient dynamics in...
Warming-induced changes in benthic redox as a potential driver of increasing benthic algal blooms in high-elevation lakes
Stephanie E. Hampton, Jill Baron, Robert Ladwig, Ryan P. McClure, Michael Frederick Meyer, Isabella Oleksy, Anna Shampain
2023, Limnology and Oceanography - Letters
Algal blooms appear to be increasing on benthic substrates of naturally nutrient-poor lakes worldwide, yet common drivers across these systems remain elusive. The phenomenon has been notable in high-elevation mountain lakes, which is enigmatic given their relative remoteness from human disturbance. We suggest that warming-induced changes in redox conditions that...

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
N. Van Schmidt, Tamara S. 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...

Bruce G. Marcot, Todd C. Atwood, David C. Douglas, Jeffrey F. Bromaghin, Anthony M. Pagano, Steven C. Amstrup
2023, Ecological Indicators (156)
Updating predictions of the response of high-profile, at-risk species to climate change and anthropogenic stressors is vital for informing effective conservation action. Here, we review two prior generations of Bayesian network probability models predicting changes in global polar bear (Ursus maritimus) population status, and provide...
Leveraging machine learning to automate regression model evaluations for large multi-site water-quality trend studies
Jennifer C. Murphy, Jeffrey G. Chanat
2023, Environmental Modeling and Software (170)
Large multi-site trend studies provide an opportunity to evaluate progress of waterbodies towards water-quality goals across broad geographic areas. Such studies often aggregate the results of site-specific models and thus contend with evaluating each model for appropriate fit and statistical...

2023, Environmental Science and Technology (57) 17511-17521
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...

Lori M Pigue, Kristen A. Bennett, Briony H.N. Horgan, Lisa Gaddis
2023, Journal of Geophysical Research: Planets (128)
Lunar Pyroclastic Deposits (LPDs) are sites of explosive volcanism and often occur in areas of effusive volcanism on the Moon. On Earth, it has been observed that most volcanism has both effusive and explosive phases, whereas on the Moon, these two types of volcanism have typically been...
