Majority Of Utahns Support Keeping Bears Ears National Monument As Originally Designated, Michaelann Nelson

Utah People and Environment Poll (UPEP)

Bears Ears National Monument in Southeastern Utah was established in 2016 by President Obama after a coalition of Native American petitioned for its designation. In 2017, during his first administration, President Trump reduced the size of the monument by 85%. It was subsequently restored to the original boundaries in 2021 by President Biden. In 2022, the Utah Legislature provided $5 million in funding for the Attorney General’s office to challenge the Bears Ears National Monument designation, and the State of Utah filed a lawsuit in August 2022 challenging the designation (1).

Remote sensing enables large-scale, image-based assessments of river dynamics, offering new opportunities for hydrological monitoring. We present a publicly available dataset consisting of 281,024 satellite and aerial images of U.S. rivers, constructed using an Application Programming Interface (API) and the U.S. Geological Survey’s National Hydrography Dataset. The dataset includes images, primary keys, and ancillary geospatial information. We use a manually labeled subset of the images to train models for detecting rapids, defined as areas where high velocity and turbulence lead to a wavy, rough, or even broken water surface visible in the imagery. To demonstrate the utility of this dataset, …

Production Tax Credits Promote U.S. Wind Power Development With A Rush To Develop Before They Expire, Michelle M. Arnold, Emily Richards, Brennan Bean, Rebekah Scott, Christopher L. Lant

Environment and Society Student Research

A statistical analysis of wind power development in each U.S. state from 2000–2022 shows that the Production Tax Credit strongly promoted wind power development, especially when it was due to expire, and producers rushed to qualify. This implies that the Inflation Reduction Act should also have an important effect in promoting wind power, with an exaggerated effect when developers perceive that tax credits will be discontinued. Physical wind power potential is positively related to wind power development among states. States with high potential selectively pass Renewable Portfolio Standards, but they have no statistically significant influence on capacity developed among the …

Coastal Conservation And Blue Carbon: Willingness To Pay For Changes To Nearshore Management In Oregon, Arthur Caplan, Marcelo Pignatari, Sarah Klain, Kreg Lindberg

Browse all Datasets

This paper reports results from a discrete choice experiment conducted with Oregon residents regarding possible policy changes in spatial management of nearshore habitat. We evaluate public preferences across several policy scenarios, each characterized by varying levels of marine reserve size (bounded areas where extractive activities are prohibited), coastal jobs generated or lost, and carbon sequestration by seagrass beds, tidal marshes and kelp forests(blue carbon habitat expansion), with models estimated in both utility and willingness to pay (WTP) space. Each of these attributes across all models displays positive, monotonic marginal WTP. Scenario analysis reveals that an “optimistic” policy package (+50 % …

Utahns' Low Concern About Wildfire Does Not Align With Growing Risk To Communities Statewide, Ashley Young, Kirsten Vinyeta, Catrin Edgeley

Utah People and Environment Poll (UPEP)

According to a national 2022 study published in the New York Times, the state of Utah bears the highest risk of property damage due to to wildfires when measured as a share of all properties.¹ These findings, coupled with Utah’s rapid population growth and accompanying residential development in fire-prone environments, present a pressing emergency preparedness challenge for federal, state and local officials. Utahns who live in the St. George metro area, which includes Dameron Valley and Washington County, face the highest possibility of harm across the state.² On July 31st, 2025, Governor Cox declared a thirty-day state of …

Most Utahns Support Affirming Rights Of Great Salt Lake, Sarah A. Woodbury, Kirsten Vinyeta, Jessica D. Ulrich-Schad, Darren Parry

Utah People and Environment Poll (UPEP)

A combination of water diversions and climate change-related shifts have led to record low water levels and increasing salinity at Great Salt Lake (GSL) (1, 2).  Low water levels not only impact those directly dependent on the lake—brine shrimpers and migratory birds, for example—but also the millions of individuals living along the Wasatch Front. Increasing toxic dust levels from exposed lakebed and potential shifts to snowpack in the region are of primary concern. Children and marginalized communities are especially vulnerable to the respiratory health impacts of toxic dust (3, 4). According to the 2023 Utah People & Environment Poll (UPEP), …

Reports

This report focuses on water conservation and provisioning strategies that both Beaver and Iron Counties are pursuing to help meet their citizens’ current and future water needs and to contribute to statewide water conservation efforts. It primarily relies on publicly available data from state, county, conservancy district, and city databases, plans, and documents. The purposes of this document are to provide regional context for understanding water use in Beaver and Iron Counties and to describe water conservation strategies that can influence the trajectories of their future water use. 

In both Beaver and Iron Counties, agriculture remains the primary user of …

Community Science For Enigmatic Ecosystems: Using Ebird To Assess Avian Biodiversity On Glaciers And Snowfields, William E. Brooks, Jordan Boersma, Neil Paprocki, Peter Wimberger, Scott Hotaling

Watershed Sciences Faculty Publications

Mountain glaciers and snowfields are rapidly receding because of climate warming. Species living in these habitats remain poorly studied, likely because of the remoteness and ruggedness of their terrain. We leveraged community science data from eBird—an online database of bird observations from around the world—to characterize bird use of mountain glaciers and snowfields. We estimated total bird biodiversity and preference for glaciers and snowfields over nearby, ice-adjacent habitats. We used field notes from eBird users and breeding codes to extend our data set to include insight into habitat usage and behavior. Finally, we compared our community-science approach to previous studies …

Development Of A High-Doppler Shift Optical Simulator To Test Femtosecond-Level Optical Time-Frequency Transfer, Matthew S. Bigelow, Kyle W. Martin, Nolan Matthews, Benjamin K. Stuhl, Richard Gonzales, Alexandre De Pinho E Braga, John Elgin, Kimberly A. Frey

Space Dynamics Laboratory Publications

We have developed an optical simulator to test real-time optical two-way time–frequency transfer at the femtosecond level capable of simulating relative motion between two linked optical clock nodes up to Mach 1.8 with no moving parts. The technique is enabled by artificially Doppler shifting femtosecond pulses from auxiliary stabilized optical frequency combs. These pulses are exchanged between the nodes to simulate the Doppler shifts observed from a changing optical path length. We can continuously scan the simulated velocity from 14 to 620 m s⁻¹ while simultaneously measuring velocity-dependent clock shifts at much higher velocities than previously recorded. This system …

Geographic And Sociodemographic Disparities In Early Hearing Detection And Intervention Adherence, Amanda Pavan, Anton Kvit, Michael Van Skiba, Analise Ristic, Kirsten R. Coverstone

Journal of Early Hearing Detection and Intervention

Early identification and intervention are crucial to minimizing impacts of congenital hearing loss. Early Hearing Detection and Intervention (EHDI) programs recommend newborn hearing screening before one month of age and a diagnostic audiologic evaluation before three months for infants who do not pass the screening. However, not all infants meet these benchmarks, as geographic and sociodemographic factors may influence adherence.

Addresses of primary contacts and audiology clinics were geocoded to calculate drive times to the nearest clinic in 10-minute intervals for infants born in Minnesota between 2019 and 2021. Birth location, NICU admittance, and sociodemographic characteristics were also analyzed. Random …

Fault Structure, Deformation Mechanisms, And Why Fault Zones Matter To Society, Elizabeth S. Petrie, David A. Ferrill, Kelly K. Bradbury, James P. Evans

Geosciences Faculty Publications

Faults are widespread geologic structures that form in sediment and all rock types, occur in all tectonic regimes, and can be a blessing or a curse to society. Faults and fault zones act as conduits for underground movement of water and as plumbing systems for aquifers and springs essential for human habitation in many semi-arid and arid regions worldwide. Faults also provide pathways for natural oil and gas migration and high-permeability zones in hydrocarbon reservoirs, as well as barriers contributing to trapping and reservoir compartmentalization. By enhancing permeability in many geothermal energy systems, faults can be essential for fluid circulation …

Data For "Large Projected Increases In Area Burned And Wildfire Frequency By 2050 In Utah, Usa", Joseph D. Birch, Yoshimitsu Chikamoto, James A. Lutz

Browse all Datasets

Changes in wildfire regimes may disrupt ecosystem processes as wildfires burn larger areas or burn more frequently than the recent natural range of variability. The climatic drivers of wildfire behavior may change in strength but these effects are not likely to be uniform across space and between different vegetation types. Increased understanding of how weather and climate influence patterns of burn area and frequency across vegetation types may assist in better predicting and managing future wildfire regimes. We examined a dataset of all 1469 wildfires ≥40 ha from 1984 – 2021 in Utah, USA and used antecedent daily weather data …
