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...

A laser rangefinder was used to record debris flows at Cascades volcanoes and an experimental debris flow flume. Mass movements such as large lahars and smaller seasonal debris flows can occur at volcanoes in the Cascades. A combination of seismic, infrasound, tripwires, and webcams can be used to detect and characterize these flows. A laser rangefinder can be placed on the banks of the drainages and pointed towards the channel as a low power, low bandwidth piece of equipment to confirm increases in flow past the station. This can serve as another piece of evidence for flows and may be able to be incoporated into future alarm systems to improve their accuracy and performance. A laser rangefinder was deployed for...

Album caption and index card: The row of shrubs marking the predam high flood stage is catclaw and has persisted with little change through almost half the century. The new riparian community comprises several species, including saltcedar, seep willow, waterweed, Emory seep willow, cattail, and desert isocoma. A rock avalanche at upper right is new since 1923. The mouth of Kanab Creek is at left foreground. Grand Canyon National Park. Coconino County, Arizona. August 24, 1972. Published as Figure 57B in U.S. Geological Survey. Professional Paper 1132. 1980.

The Climate Adaptation Science Centers (CASCs) partner with natural and cultural resource managers, tribes and indigenous communities, and university researchers to provide science that helps fish, wildlife, ecosystems, and the communities they support adapt to climate change. The CASCs provide managers and stakeholders with information and decision-making tools to respond to the effects of climate change. While each CASC works to address specific research priorities within their respective region, CASCs also collaborate across boundaries to address issues within shared ecosystems, watersheds, and landscapes. These shapefiles represent the 9 CASC regions and the national CASC that comprise the CASC network, highlighting...

The watershed data management (WDM) database SC16.WDM is updated with the processed data for the period October 1, 2016, through September 30, 2017, and renamed as SC17.WDM. The precipitation data are collected from a tipping-bucket rain-gage network and the hydrologic data (stage and discharge) are collected at USGS streamflow-gaging stations in and around DuPage County, Illinois. Hourly precipitation and hydrologic data for the period October 1, 2016, through September 30, 2017, are processed following the guidelines described in Bera (2014) and appended to SC16.WDM and renamed as SC17.WDM. Meteorological data (wind speed, solar radiation, air temperature, dewpoint temperature, and potential evapotranspiration)...

Model archive summary (MAS) describing the development of a continuous 15-minute suspended-sediment concentration (SSC) time series regression model for the site: Georgiana Slough Near Sacramento River (U.S. Geological Survey (USGS) site # 11447903). The SSC time series is computed from instream turbidity data that is managed by the USGS using a YSI EXO multi-parameter water quality sonde.

Coastal ecosystems are uniquely vulnerable to changes in the quantity and quality of freshwater discharge. With a warming climate, changes in freshwater discharge into estuaries will interact with rising sea levels. Natural resource managers in coastal areas are looking for guidance on the potential impacts and vulnerabilities to better manage the risks to aquatic species and habitats, and to mitigate species decline or collapse resulting from changes in freshwater availability. In particular, managers and researchers are concerned with producing appropriate ecological flows, which describe the conditions of river and stream flow into estuaries that are needed to ensure the proper structure and function of coastal...

This data release consists of multi-band 30-meter x 30-meter pixel rasters of estimated population and domestic self-supplied water withdrawals in Rhode Island between July 2014 and June 2021. Population raster data were generated using a national data product of 2010 population spatially distributed across land cover data and U.S. Census Bureau data of population growth estimates to adjust populations for each year 2014-2021. Estimates for changes in population between winter and summer months are also included to generate seasonal population estimates. The coefficients used to describe these variations in populations for each U.S. Census Bureau block group in Rhode Island are included in this data release. Estimated...
Hurricane Maria caused widespread landsliding throughout Puerto Rico during September 2017. Previous detailed landslide inventories following the hurricane include Bessette-Kirton et al. (2017, 2019). Here we continue that work with an in-depth look at a portion of northwest Naranjito, which is a municipality in the northeastern part of the main island. To study a characteristic sample of landslides in Naranjito, we mapped all visible individual landslides in an approximately triangular area 2.3 km wide by 1.9 km long. The boundary of our mapping was defined by previous studies (Bessette-Kirton et al., 2019). We used aerial imagery collected between 9-15 October 2017 (Quantum Spatial, Inc., 2017) to map landslide...

The geochemical data included here were generated as part of a Technical Assistance Agreement between the U.S. Geological Survey (USGS) and Rio Tinto Exploration based in Salt Lake City, Utah. Beginning in November of 2015, we began a project to reanalyze up to 60,000 archived sample splits originally collected as part of the National Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) project from selected areas in Arizona, California, Idaho, Montana, Nevada, New Mexico, and Utah. A small amount (approximately 0.25 g) of sieved <75 micron sample material was retrieved from the USGS National Geochemical Sample Archive for geochemical analysis. These samples were analyzed...
