The NABat sampling frame is a grid-based finite-area frame spanning Canada, the United States, and Mexico consisting of N total number of 10- by 10-km (100-km2) grid cell sample units for the continental United States, Canada, and Alaska and 5- by 5-km (25km2) for Hawaii and Puerto Rico. This grain size is biologically appropriate given the scale of movement of most bat species, which routinely travel many kilometers each night between roosts and foraging areas and along foraging routes. A Generalized Random-Tessellation Stratified (GRTS) Survey Design draw was added to the sample units from the raw sampling grids (https://doi.org/10.5066/P9M00P17). This dataset represents the final 2018 NABat Sampling grid with...

These data are a summary of modeled exposure of various lifeline infrastructure linear features and facilities (transportation, water supply and wastewater, oil and gas, electric power, and telecommunications) to potential hazards resulting from the HayWired earthquake scenario, a magnitude 7.0 earthquake occurring on the Hayward Fault on April 18, 2018, with an epicenter in the city of Oakland, CA. Existing hazard data (surface offset, ground shaking (mainshock and aftershocks), landslide, liquefaction, and fire following earthquake) were looked at alone and in combination with each other relative to the lifeline infrastructure linear features and facilities to provide estimates of potential exposure to various...

This data release contains monthly 270-meter resolution Basin Characterization Model (BCMv8) climate and hydrologic variables for Localized Constructed Analog (LOCA; Pierce et al., 2014)-downscaled ACCESS 1.0 Global Climate Model (GCM) for Representative Concentration Pathway (RCP) 4.5 (medium-low emissions) and 8.5 (high emissions) for hydrologic California. The LOCA climate scenarios span water years 1950 to 2099 with greenhouse-gas forcings beginning in 2006. The LOCA downscaling method has been shown to produce better estimates of extreme events and reduces the common downscaling problem of too many low-precipitation days (Pierce et al., 2014). Ten GCMs were selected from the full ensemble of models from the...
This sampling frame is a set of grid-based finite-area frames spanning Canada, the United States, and Mexico. The grid for the United States is broken into individual grids for the continental United States, Hawaii, and Puerto Rico. Alaska is combined with Canada into a single grid. Each country/state/territory extent consists of four nested sampling grids at 50x50km, 10x10km, 5x5km, and 1x1km resolutions. The original 10x10km continental United States grid was developed by the Forest Service, U.S. Department of Agriculture for use in the interagency “Bat Grid” monitoring program in the Pacific Northwest and was expanded across Canada, the United States, and Mexico for the North American Bat Monitoring Program (NABat)....

These data are a geospatial representation of potential moderate or high ground shaking intensity for seven M5 or greater aftershocks resulting from the HayWired earthquake scenario, a magnitude 7.0 earthquake occurring on the Hayward Fault on April 18, 2018, with an epicenter in the city of Oakland, CA. These data take existing ground shaking data for the HayWired mainshock and seven aftershocks (M6.21 Palo Alto, M5.69 Palo Alto, M5.22 Palo Alto, M5.26 Palo Alto, M5.98 Mountain View, M6.40 Cupertino, and M5.35 Sunnyvale) and combine them into a single ground shaking intensity surface intended for estimating possible repeat exposure to moderate or high intensity ground shaking. This vector .SHP dataset was developed...

The U.S. Geological Survey acquired high-resolution P- and S-wave seismic data across the Frijoles Fault strand of the San Gregorio Fault Zone (SGFZ) at northern Año Nuevo, California in 2012. SGFZ is a right-lateral fault system that is mainly offshore, and prior studies provide highly variable slip estimates, which indicates uncertainty about the seismic hazard it poses. Therefore, the primary goal of the seismic survey was to better understand the structure and geometry of the onshore section of the Frijoles Fault strand of the SGFZ. We deployed 118 geophones (channels) at 5-m spacing along a linear profile centered on the mapped surface trace of the Frijoles Fault and co-located active P- and S-wave sources...

This dataset represents 505 campsites along the Colorado River in Grand Canyon with associated debris flow probabilities calculated for approximately a 100-year period (Griffiths and others, 2004) and geomorphic attributes mapped by the U.S. Geological Survey, Grand Canyon Monitoring and Research Center (USGS-GCMRC) (Hadley and others, 2018). The campsite polygons were developed as part of a master campsite database that was a collaborative effort to maintain between the National Park Service in Grand Canyon National Park and the USGS-GCMRC. Debris flow probabilities have been added as an attribute from ungauged tributary watersheds published in 2004 (Griffiths and others, 2004). Area and percentages of campsites...

This data set contains estimates of bedload transport entering San Francisco Bay from the Sacramento-San Joaquin Delta. Bedload was estimated following the methods of van Rijn (1984) for the Sacramento River at Rio Vista (USGS 11455420) and the San Joaquin River at Jersey Point (USGS 11337190). The inputs the van Rijn (1984) equations included:bed-material particle size, bed-form dimensions, depth, and velocity. Bedload was estimated at 15-minute intervals from Water Year 2011 through Water Year 2020. A "low range" estimate and a "high range" estimate were made. The low-range estimate assumes plane bed conditions and uses only grain size to estimate a hydraulic roughness parameter. The high-range estimate incorporates...

As part of a large-scale study of nitrate contamination on Kirtland Air Force Base in central New Mexico, the USGS collected groundwater and surface water samples for artificial sweetener analyses. Samples were collected following standard USGS procedures (U.S. Geological Survey, variously dated), filtered to 0.45 microns, and frozen until analysis. Artificial sweeteners analyzed include neotame, acesulfame-K, aspartame, saccharin, and sucralose. Of the 49 sites sampled, 17 sites had measurable detections of artificial sweeteners. Neotame was the most commonly detected sweetener (n=12) followed by saccharin (n=5), acesulfame-K (n=2), aspartame (n=1), and sucralose (n=0). Concentrations ranged from 0.0003–0.011 μg/L...

This dataset represents 740 tributary canyons and/or watersheds adjacent to the Colorado River in Grand Canyon with associated debris flow probabilities from 2004. Also, these data include tributarys canyon and/or watersheds to Glen Canyon and several smaller watersheds in Grand Canyon where debris flow data is currently unavailable. Historic probabilities of debris flow occurrence were estimated by modeling the known frequency distribution with drainage basin parameters observed to control the process by which debris flows initiate and travel to the river. Observations from 1984 through 2003 provide a 20-year record of all debris flows that reached the Colorado River in Grand Canyon, and repeat photography provides...
