This dataset provides estimated Remote Sensing Streamflow (RSQ) data at selected river reaches in Alaska. Reach-specific relations between satellite-derived water-surface elevation data and dynamic surface water extent data were used with a modified form of the Manning's streamflow equation to estimate streamflows. The streamflow estimates were used to create rating tables that define the relation between discharge and satellite-observed water-surface elevation. The streamflow estimates in the gage_data.csv files are derived from these rating tables, interpolated using a polynomial regression equation. Data are organized in child items named for each river reach. Reach-specific details are provided in a README file...

Project Overview Restoring grass-dominated landscapes into resilient forested ecosystems is a key strategy for addressing the growing risk of wildfire Hawaiʻi. However, conventional afforestation efforts typically require regular maintenance due to the persistent invasion of grasses in planted areas. In collaboration with Native Hawaiian Organizations, researchers supported by this Pacific Islands CASC project will test dense plantings of keystone species and intensive mulching, aiming to restore traditional agroforest ecosystems that support cultural practices and improve disaster mitigation. Public Summary With the growing threat of wildfires in Hawaiʻi, highlighted by recent events such as the Lahaina wildfires,...

Album caption and ndex card: Petrified sand dunes, looking northeast from the park road 2.7 miles north of Courthouse Wash. The Navajo Sandstone was once a huge sand pile of dunes laid down by winds during an arid interval, so it is interesting to note that the irregularly weathered sandstone once again resembles a pile of cross-bedded dunes. Arches National Park. Grand County, Utah. July 11, 1972. Note: Published as figure 32, U.S. Geological Survey. Bulletin 1393. 1975. See also: lsw00045

Using a solutions-oriented, multi-agency collaboration, we propose to pilot a large-scale assessment of an alternative (herding, electric- and virtual-fence) grazing strategy designed to mimic pre-colonial grazing patterns by bison, to ascertain their value for local- and regional-scale assemblages ofsagebrush- and grassland-associated birds in Montana. A fundamental goal of most wildlife-based grazing programs is to foster a mosaic of patches that represent the broadest possible spectrum of habitat types that benefits different sagebrush- and grassland-associated birds in different parts of the landscape (for example, western meadowlarks, vesper sparrows, and thick-billed longspur in open, heavily grazed areas;...

Conifer removal and management is a key tool for restoring sagebrush ecosystems and Greater Sage-Grouse populations, though the response of other sagebrush-obligate birds, including Pinyon Jays, to conifer management has not been well-studied. Quantifying the response of avian species to conifer management will inform conservation delivery to ensure that agencies achieve sagebrush bird and habitat objectives while minimizing impacts on Pinyon Jays in the sagebrush/pinon-juniper woodland ecotone. The results of this project will address key science needs on Pinyon Jays and directly inform more effective conifer management throughout the eastern Great Basin. Without these data, we will be unable to provide science-based...

The US Prairie Pothole Region (PPR) has experienced some of the highest rates of grassland loss in North America over a time that coincides with dramatic declines in grassland songbird populations yet increasing abundance of most grassland-nesting duck species except for northern pintail. To provide more insight into this contradiction, we propose to capitalize on long-term databases to evaluate how a key population driver nest survival for North American ducks has responded to system changes in the region including landscape and climatic factors. Outcomes of these analyses will contribute to testing primary conservation planning assumptions for the PPJV a vital component of the PPJV Strategic Habitat Conservation...

Insect pollinators-particularly native bees-are critically important in the maintenance of terrestrial plant and animal communities, yet our understanding of how contemporary threats influence this group and the pollination services they provide is virtually unstudied with the sagebrush biome. Our investigation will quantify how bee communities respond to widespread threats to sagebrush-wildfire and invasive annual grasses-and provide foundational knowledge needed for undertaking informed management decisions to improve the resilience of the biome.

The development and deployment of digital broadband seismographs provides the data required to rapidly assess earthquake size, determine source parameters and better characterize ground motions affecting earthquake hazard. The focus of regional moment tensor analysis is to estimate the moment magnitude, faulting parameters and source depth of earthquakes that are too small to be recorded teleseismically. Thus they have the potential of extending the earthquake catalog to magnitudes less than about M4-4.5.

The focus of regional moment tensor analysis is to estimate the moment magnitude, faulting parameters and source depth of earthquakes that are too small to be recorded teleseismically. Thus they have the potential of extending the earthquake catalog to magnitudes less than about M4-4.5. This data distribution provides the details required to critically review the resulting catalog, e.g., the waveforms used, processing parameters and velocity model. In addition the issue of the correct local magnitude...
This dynamic data release presents an aquatic reflectance product with 20-meter spatial resolution derived from Sentinel-2 satellite imagery for the conterminous United States using the Atmospheric Correction for OLI “lite” (ACOLITE). Aquatic reflectance, noted Rhow in ACOLITE documentation, is defined here as unitless water-leaving radiance reflectance and represents the ratio of water-leaving radiance (units of watts per square meter per steradian per nanometer) to downwelling irradiance (units of watts per square meter per nanometer) multiplied by π. This is also known as remote sensing reflectance (units of per steradian) multiplied by π. These data are intended for use in remote sensing of water color and differ...

The Integrated Water Availability Assessment uses an ensemble of outputs from two hydrologic models to assess water supply conditions. Results from the two models, the National Hydrologic Model Precipitation-Runoff Modeling System (NHM-PRMS) and Weather Research and Forecasting model hydrologic modeling system (WRF-Hydro) were averaged to create a single model ensemble. A unique instance of each model was developed specifically for this application (see the following data releases listed in the related external resources below: Sampson et al., 2024; Foks et al., 2025; Foks et al., 2024a-c). Each model was run at its native spatiotemporal resolution and converted to the subwatershed (12-digit hydrologic unit code;...

Feral horse populations in the southwestern United States, including on tribal lands, are far above sustainable levels. This overpopulation poses threats to rangeland ecosystems as the feral horses compete with native species and livestock for limited resources – which likely will become even more limited with climate change. Researchers supported by this Southwest CASC project will partner with tribal agencies to generate reliable population size estimates of feral horse populations. These estimates are essential for tribal agencies to create effective management plans to protect rangelands. Overabundant feral horse populations are a major concern on southwestern rangelands because of their tendency to degrade...

This data release makes available the data used to test a method for remote sensing of river discharge based on critical flow theory. In rivers where flow conditions are near critical and well-defined standing waves are present, simple measurements of the wavelengths of the standing waves and the width of the channel made using readily available image data can be used to infer river discharge. This approach could provide an efficient, non-contact method of estimating streamflow in certain rivers. Sites near established USGS gaging stations with standing waves (also known as undular hydraulic jumps) were identified by examining images within Google Earth Pro (https://www.google.com/earth/about/versions/#earth-pro)....

The Conservation Efforts Database (CED) in a web-based monitoring and reporting tool that captures data about the conservation, restoration, and recovery actions for the imperiled sagebrush ecosystemand sage-grouse. Funding support from FWS (Science Applications and Nevada Ecological Services) have allowed the CED Team to develop a module for recording data about conservation actions, habitat condition, demography, and genetic information for Lahontan Cutthroat Trout and we propose to expand that effort to include aquatic systems in Legacy Region 6. We propose to use funding to engage with stakeholders to scope the information gaps and tool needs to record and monitor conservation actions and information focused...
