Identifying preferential flow from soil moisture time series: Review of methodologies Identifying preferential flow from soil moisture time series: Review of methodologies
Identifying and quantifying preferential flow (PF) through soil—the rapid movement of water through spatially-distinct pathways in the subsurface—is vital to understanding how the hydrologic cycle responds to climate, land cover, and anthropogenic changes. In recent decades, methods have been developed that use measured soil moisture time series to identify PF. Because they allow for...

The GorDAS Distributed Acoustic Sensing experiment above the Cascadia locked zone and subducted Gorda Slab The GorDAS Distributed Acoustic Sensing experiment above the Cascadia locked zone and subducted Gorda Slab
The southernmost portion of the Cascadia Subduction zone in Northern California produces high rates of moderate and large earthquakes owing to subduction of the Gorda slab and deformation associated with the Mendocino Triple Junction. Distributed Acoustic Sensing (DAS) is rapidly advancing as a method for detecting earthquakes and imaging crustal structure. We have begun a long-term DAS...

Rapid butterfly declines across the United States during the 21st century Rapid butterfly declines across the United States during the 21st century
Reports of declining insect populations have received widespread media attention, but evidence for declines has been variable across regions and taxonomic groups. Edwards et al. examined trends in the most surveyed taxon: butterflies (see the Perspective by Inouye). Combining data from 35 citizen science programs across the continental US, the authors found declines in overall butterfly...

A survey of mammal and fish genetic diversity across the global protected area network A survey of mammal and fish genetic diversity across the global protected area network
Global conservation targets aim to expand protected areas and maintain species’ genetic diversity. Whether protected areas capture genetic diversity is unclear. We examined this question using a global sample of nuclear population-level microsatellite data comprising genotypes from 2513 sites, 134,183 individuals, and 176 mammal and marine fish species. The genetic diversity and...

Impact of thermoelectric power plant operations and water use reporting methods on thermoelectric power plant water use Impact of thermoelectric power plant operations and water use reporting methods on thermoelectric power plant water use
Thermoelectric power generation accounts for over 41% of total U.S. freshwater withdrawals, making understanding the determinants of power plants’ water withdrawals (WW) and consumption (WC) critical for reducing the sector’s reliance on increasingly scarce water resources. However, reported data inconsistencies and incomplete analysis of potential determinants of thermoelectric water...

Developing a probabilistic tsunami hazard assessment framework for Pacific sources: USGS Powell Center meeting summary Developing a probabilistic tsunami hazard assessment framework for Pacific sources: USGS Powell Center meeting summary
Multi-organizational principal investigators formed a U.S. Geological Survey (USGS) Powell Center Working Group (WG), Tsunami Source Standardization for Hazards Mitigation in the United States, to develop a comprehensive series of sources capable of generating tsunamis that could impact U.S. state and territory coastal areas using probabilistic tsunami hazard analysis (PTHA). PTHA...

A fire deficit persists across diverse North American forests despite recent increases in area burned A fire deficit persists across diverse North American forests despite recent increases in area burned
Rapid increases in wildfire area burned across North American forests pose novel challenges for managers and society. Increasing area burned raises questions about whether, and to what degree, contemporary fire regimes (1984–2022) are still departed from historical fire regimes (pre-1880). We use the North American tree-ring fire-scar network (NAFSN), a multi-century record comprising...

Spatiotemporal synchrony of climate and fire occurrence across North American forests (1750-1880) Spatiotemporal synchrony of climate and fire occurrence across North American forests (1750-1880)
Aim Increasing aridity has driven widespread synchronous fire occurrence in recent decades across North America. The lack of historical (pre-1880) fire records limits our ability to understand long-term continental fire-climate dynamics. The goal of this study is to use tree-ring reconstructions to determine the relationships between spatiotemporal patterns in historical climate and...

Advancing the science of headwater streamflow for global water protection Advancing the science of headwater streamflow for global water protection
The protection of headwater streams faces increasing challenges, exemplified by limited global recognition of headwater contributions to watershed resiliency and a recent US Supreme Court decision limiting federal safeguards. Despite accounting for ~77% of global river networks, the lack of adequate headwaters protections is caused, in part, by limited information on their extent and...

The interplay of future solar energy, land cover change, and their projected impacts on natural lands and croplands in the US The interplay of future solar energy, land cover change, and their projected impacts on natural lands and croplands in the US
Projections for deep decarbonization require large amounts of solar energy, which may compete with other land uses such as agriculture, urbanization, and conservation of natural lands. Existing capacity expansion models do not integrate land use land cover change (LULC) dynamics into projections. We explored the interaction between projected LULC, solar photovoltaic (PV) deployment, and...
