Invasive Round Goby in the Mohawk and Hudson Rivers: What’s the latest? Invasive Round Goby in the Mohawk and Hudson Rivers: What’s the latest?
The Round Goby (Neogobius melanostomus) is an invasive benthic fish indigenous to the Ponto-Caspian region of Eurasia. It recently colonized the Great Lakes and has expanded eastward through the New York State Canal System over the past decade. The species was first documented in the Mohawk River watershed in 2014 and was found in the Hudson River in 2021. Round Goby can adversely affect...

Magnetotelluric monitoring of the Geysers Steam Field, northern California: Phase 2 Magnetotelluric monitoring of the Geysers Steam Field, northern California: Phase 2
An original magnetotelluric (MT) survey collected in 2017 included 42 MT stations mainly in the northwestern part of The Geysers geothermal field in northern California. These data were modeled in 3D and imaged the electrically conductive cover, the electrically resistive steam field, and the electrically resistive Geysers plutonic complex (Peacock et al., 2020; Peacock et al. 2020a)...

Reconstructing the geomorphic evolution and sediment budget history of a dynamic barrier island: Anclote Key, Florida Reconstructing the geomorphic evolution and sediment budget history of a dynamic barrier island: Anclote Key, Florida
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 Key via its morphostratigraphy, a presently...

City-scale geothermal energy everywhere to support renewable resilience – A transcontinental cooperation City-scale geothermal energy everywhere to support renewable resilience – A transcontinental cooperation
Cities have important and varying incentives to transform their energy sector to all-electric with low carbon emissions. However, they often encounter a number of impediments when attempting to implement such a change. For example, while urban areas have the highest energy demand-density, cities often lack the space for installing additional energy generation and/or long-duration energy...

Effect of thermal and mechanical processes on hydraulic transmissivity evolution Effect of thermal and mechanical processes on hydraulic transmissivity evolution
Fracture healing is a critical component of enhanced geothermal systems, the earthquake cycle, and induced seismicity. Accordingly, there is significant interest in understanding the process of healing and its effects on fluid transport. The creation, reactivation, and sustainability of fracture networks depend on complex coupling among thermal, hydraulic, mechanical, and chemical...

New maps of conductive heat flow in the Great Basin, USA: Separating conductive and convective influences New maps of conductive heat flow in the Great Basin, USA: Separating conductive and convective influences
Geothermal well data from Southern Methodist University and the U.S. Geological Survey (USGS) were used to create maps of estimated background conductive heat flow across the Great Basin region of the western United States. These heat flow maps were generated as part of the USGS hydrothermal and Enhanced Geothermal Systems resource assessment process, and the creation process seeks to...

During Nearshore Event Experiment (DUNEX): A collaborative community field data collection effort During Nearshore Event Experiment (DUNEX): A collaborative community field data collection effort
The DUring Nearshore Event eXperiment (DUNEX) is an academic, federal agency, and non-government collaborative community experiment supported by and planned under the U.S. Coastal Research Program (USCRP) to study nearshore coastal processes during storms. The motivation for DUNEX is to improve understanding, numerical representation, and prediction of storm processes and impacts; to...

Ground motion selection for nonlinear response history analyses of concrete dams Ground motion selection for nonlinear response history analyses of concrete dams
Evaluating the seismic performance of a 3D concrete dam using nonlinear response history analysis (NLRHA) requires three orthogonal components of ground acceleration histories, or ground motions (GMs) for brevity. Although much progress has been made for the topic of ground motion selection and modification (GMSM) in the context of multistory buildings, NLRHA of dams requires at least...

Three-decades of Rocky Intertidal Photo Series Documenting interannual variability in western Prince William Sound Three-decades of Rocky Intertidal Photo Series Documenting interannual variability in western Prince William Sound
During summer 2021 we re-visited and re-photographed intertidal community scenes at seven rocky intertidal sites in Western Prince William Sound, adding another year of photos to a 32-year monitoring effort. The sites include both previously-oiled and un-oiled locations that were the subject of repeated annual photos beginning in 1990, one year after the March 24, 1989 Exxon Valdez Oil...

Assessing the efficacy of oblique bubble screens for control of aquatic invasive species Assessing the efficacy of oblique bubble screens for control of aquatic invasive species
Non-physical barriers, such as bubble screens (or curtains), are promising low-impact strategies to deter the spread of Aquatic Invasive Species (AIS) in streams. Bubble screens have been successfully implemented to redirect and/or deter adult fish and to capture plastics in some rivers, but their efficacy on invasive fish at multiple life stages (eggs, larvae, and adult fish) is not yet...
