Assessment of undiscovered, technically recoverable conventional oil and gas resources in the Upper Jurassic Smackover Formation, U.S. Gulf Coast, 2022 Assessment of undiscovered, technically recoverable conventional oil and gas resources in the Upper Jurassic Smackover Formation, U.S. Gulf Coast, 2022
Using a geology-based assessment methodology, the U.S. Geological Survey estimated undiscovered, technically recoverable mean resources of 143 million barrels of oil and 1,084 billion cubic feet of natural gas in conventional accumulations for the Upper Jurassic Smackover Formation in the onshore U.S. Gulf Coast region.

National shoreline change—Summary statistics of shoreline change from the 1800s to the 2010s for the coast of California National shoreline change—Summary statistics of shoreline change from the 1800s to the 2010s for the coast of California
Rates of shoreline change have been updated for the open-ocean sandy coastline of California as part of studies conducted by the U.S. Geological Survey. Shorelines from the original assessment (1800s through 1998 or 2002), as well as additional shoreline position data from 2009 to 2011, 2015, and 2016 extracted from light detection and ranging (lidar) data, were used to compute long-term...

National-scale remotely sensed lake trophic state from 1984 through 2020 National-scale remotely sensed lake trophic state from 1984 through 2020
Lake trophic state is a key ecosystem property that integrates a lake’s physical, chemical, and biological processes. Despite the importance of trophic state as a gauge of lake water quality, standardized and machine-readable observations are uncommon. Remote sensing presents an opportunity to detect and analyze lake trophic state with reproducible, robust methods across time and space...

Nanoscale silicate melt textures determine volcanic ash surface chemistry Nanoscale silicate melt textures determine volcanic ash surface chemistry
Explosive volcanic eruptions produce vast quantities of silicate ash, whose surfaces are subsequently altered during atmospheric transit. These altered surfaces mediate environmental interactions, including atmospheric ice nucleation, and toxic effects in biota. A lack of knowledge of the initial, pre-altered ash surface has required previous studies to assume that the ash surface...

Bringing partners together: A symposium on native lampreys and the Pacific Lamprey Conservation Initiative Bringing partners together: A symposium on native lampreys and the Pacific Lamprey Conservation Initiative
A symposium at the 2022 American Fisheries Society meeting highlighted collaborations among biologists, policymakers, and Native American tribes addressing conservation for native lampreys. We present key findings from the symposium and related research and an example of grassroots effort to protect and restore Pacific Lamprey.

Assessing the accuracy of OpenET satellite-based evapotranspiration data to support water resource and land management applications Assessing the accuracy of OpenET satellite-based evapotranspiration data to support water resource and land management applications
Remotely sensed evapotranspiration (ET) data offer strong potential to support data-driven approaches for sustainable water management. However, practitioners require robust and rigorous accuracy assessments of such data. The OpenET system, which includes an ensemble of six remote sensing models, was developed to increase access to field-scale (30 m) ET data for the contiguous United...

Shoreline slope influences movements of larval lampreys over dewatered substrate Shoreline slope influences movements of larval lampreys over dewatered substrate
Larval lampreys are filter feeders that live for several years burrowed in fine sediments in freshwater streams. Stream side channels and edges, where larval lampreys gather, are vulnerable to natural and human-caused dewatering. Water level reductions can strand and kill thousands of larval lampreys, in part because many remain burrowed until their habitats are exposed, at which point...

Opportunities for improved consideration of cultural benefits in environmental decision-making Opportunities for improved consideration of cultural benefits in environmental decision-making
Many cultural benefits of ecosystem services (ES) are difficult to capture in standard ES assessments. Scholars and practitioners often respond to this gap by seeking to develop new scientific methods to capture and integrate the plural values associated with diverse cultural benefits categories. This increasing emphasis on value pluralism represents an essential step toward...

Prey selection by black-footed ferrets (Mustela nigripes): Implications for intersexual resource partitioning and conservation Prey selection by black-footed ferrets (Mustela nigripes): Implications for intersexual resource partitioning and conservation
Intraspecific resource partitioning may play a critical role in how predators optimize prey selection. The Black-footed Ferret (Mustela nigripes; henceforth, ferret) is a highly specialized predator of prairie dogs (Cynomys spp.; henceforth, PDs). Adult ferrets are sexually dimorphic and PDs are of similar size making them a difficult prey item. PD young are born 6 to 8 weeks prior to...

Saltwater intrusion and sea level rise threatens U.S. rural coastal landscapes and communities Saltwater intrusion and sea level rise threatens U.S. rural coastal landscapes and communities
The United States (U.S.) coastal plain is subject to rising sea levels, land subsidence, more severe coastal storms, and more intense droughts. These changes lead to inputs of marine salts into freshwater-dependent coastal systems, creating saltwater intrusion. The penetration of salinity into the coastal interior is exacerbated by groundwater extraction and the high density of...
