Data

This data set contains U-Pb isotopic data and associated ages of titanite from one sample and detrital zircon grains from 33 sedimentary and metasedimentary rocks collected from the western Alaska Range in south-central Alaska. The samples were collected as part of geological mapping and research conducted between 2010 and 2014 and funded by the Mineral Resources Program of the U.S. Geological Sur

The need to monitor change in sagebrush steppe is urgent due to the increasing impacts of climate change, shifting fire regimes, and management practices on ecosystem health. Remote sensing provides a cost-effective and reliable method for monitoring change through time and attributing changes to drivers. We report an automated method of mapping rangeland fractional component cover over a large po

This archive documents five 30-year SUTRA simulations summarized in Burns at al. (2020), and provides output from one short (2-year) simulation to allow verification that the archive model code runs properly. A modified version of SUTRA 2.2 was used to evaluate Reservoir Thermal Energy Storage by simulating layered system conditions (grid spacing varies depending on simulation run time to prevent

This dataset includes data on the growth, fecundity, and survival of Giant Gartersnakes (Thamnophis gigas) in the Sacramento Valley of California from 1995-2017. In addition, the dataset includes R code to replicate the Integral Projection Model construction and analysis presented in the paper "Demographic drivers of population growth in a threatened snake" by Rose et al. published in Journal of W

The data set includes feeding observations of black abalone (Haliotis cracherodii) at long-term intertidal monitoring sites around San Nicolas Island, California from 1982 - 2019. This includes site locations, sites, date of observation, observed food items, and abalone shell length when available. Seasonal (spring and fall) GIS maps of giant kelp (Macrocystis pyrifera) canopy distributions from t

This data release contains daily time series estimates of natural streamflow at the outlets of more than 80,000 12-digit hydrologic units in 19 study regions across the conterminous U.S. from October 1, 1980 through September 30, 2017, using three statistical techniques: Nearest-Neighbor Drainage Area Ratio (NNDAR), Map-Correlation Drainage Area Ratio (MCDAR), and Ordinary Kriging of the logarithm

The data document the results of several microbe bioassays performed by the USGS on Phragmites australis plants, including those performed on mature leaves, seedlings, and dead leaf tissues exploration of the literature to find accounts of microbes associated with Phragmites worldwide. For the bioassays, we prepared 162 pure cultures isolated from Phragmites plants in North America along the east

This field activity is part of the effort to map geologic substrates of the Stellwagen Bank National Marine Sanctuary region off Boston, Massachusetts. The overall goal is to develop high-resolution (1:25,000) interpretive maps, based on multibeam sonar data and seabed sampling, showing surficial geology and seabed sediment dynamics. This cruise was conducted in collaboration with the Stellwagen B

The table illustrates global patterns of betacoronavirus (β-CoV) associations in bats. The table lists bat species in which betacoronaviruses (β-CoVs) were detected, organized by viral subgenera and clade [for Sarbecorviruses], bat family, bat suborder, and general global region where the species of bat occurs. Reference to the published literature sources of information for each row are listed in

This data release is comprised of geospatial and tabular data developed for the HayWired communities at risk analysis. The HayWired earthquake scenario is a magnitude 7.0 earthquake hypothesized to occur on the Hayward Fault on April 18, 2018, with an epicenter in the city of Oakland, CA. The following 17 counties are included in this analysis unless otherwise specified: Alameda, Contra Costa, Ma

The data in this data release are comprised of one geospatial vector dataset and three tabular datasets related to the HayWired earthquake scenario, a magnitude 7.0 earthquake hypothesized to occur on April 18, 2018, with an epicenter in the city of Oakland, CA. The geospatial vector data are a representation of identified economic subareas for use in selected analyses related to selected countie

Measurements of suspended sediment concentration, water velocity, suspended-sediment particle size, and suspended-sediment particle settling velocity were collected to estimate suspended-sediment flux and investigate sediment transport processes at Dumbarton Bridge in San Francisco Bay (NWIS station 373015122071000) from calendar year 2018 to 2019. Data were collected using: stationary and boat-mo
