Historical produced water chemistry data compiled for the Orcutt and Oxnard oil fields, Santa Barbara and Ventura Counties, southern California Historical produced water chemistry data compiled for the Orcutt and Oxnard oil fields, Santa Barbara and Ventura Counties, southern California
This digital dataset represents historical geochemical and other information for 58 sample results of produced water from 56 sites in the Orcutt and Oxnard oil fields in Santa Barbara and Ventura Counties, respectively, in southern California. Produced water is a term used in the oil industry to describe water that is produced as a byproduct along with the oil and gas. The locations from...
High-resolution seismic imaging of the West Napa Fault Zone at Buhman Avenue, Napa, California High-resolution seismic imaging of the West Napa Fault Zone at Buhman Avenue, Napa, California
In November 2016, the U.S. Geological Survey acquired high resolution P- and S-wave seismic data across the trace of the West Napa Fault zone near Buhman Avenue in Napa, California. The primary goal of the seismic survey was to image the subsurface damage from the 2014 MW 6.0 South Napa earthquake to assist in a near-surface fault slip and deformation investigation. We acquired seismic...

Walrus Haulout Photographs Near Pt. Lay Alaska, September 2014 Walrus Haulout Photographs Near Pt. Lay Alaska, September 2014
These data are three sets of aerial photos used to estimate the number of walruses at a haulout near Pt. Lay, Alaska in September 2014. They were collected during photographic aerial surveys of the only major haulout that occurred on the eastern shores of the Chukchi Sea after sea ice receded beyond the continental shelf on 25 and 27 September 2014.
Data Report for Nodal Seismograph Recording at the Byerly Seismographic Vault, University of California, Berkeley, California Data Report for Nodal Seismograph Recording at the Byerly Seismographic Vault, University of California, Berkeley, California
In September and October 2019, the USGS and UC Berkeley (UCB) deployed two nodal seismographs at the Byerly Seismographic Vault (station BRK), east of the UCB campus. One of the nodes was located immediately outside the vault, and the other was located within the vault, adjacent to a broadband seismometer. The objective of this deployment was to compare recordings of local earthquakes...
Contiguous US and Global streamflow gages measuring zero flow Contiguous US and Global streamflow gages measuring zero flow
We report the site number and locations of 5798 streamflow gages displaying zero flow for at least one day in their daily records. 4891 of these gages are from the GRDC network, and 906 are USGS gages in the contiguous US. Additionally, provisional data for two USGS gages 1) Rio Puerco near Bernardo, NM (USGS site: 08353000) and 2) Agua Fria River Near Mayer, AZ (USGS site: 09512500) are...
Sub-annual streamflow responses to rainfall and snowmelt inputs in snow-dominated watersheds of the western U.S. Sub-annual streamflow responses to rainfall and snowmelt inputs in snow-dominated watersheds of the western U.S.
The data presented here contain quasi-event hydrologic response characteristics for quickflow response intervals (QRIs) calculated at 57 USGS GAGES-II reference watersheds in the western US. Each row in the attached csv contains characteristics for an individual QRI at one site. QRI characteristics include duration, antecedent flow, input, input rate,peak flow, potential...
Data for statewide assessment of New York's karst aquifers with an inventory of closed-depression and focused-recharge features Data for statewide assessment of New York's karst aquifers with an inventory of closed-depression and focused-recharge features
The New York State Departments of Environmental Conservation and Health are concerned about groundwater contamination in the carbonate-bedrock aquifers with the potential to host karst features throughout New York State, especially relating to the unintended introduction of chemical or agricultural contamination into these aquifers. USGS Scientific Investigations Report, SIR 2020-5030...
Largemouth bass population assessment within flooded islands of the Sacramento-San Joaquin Delta Largemouth bass population assessment within flooded islands of the Sacramento-San Joaquin Delta
Field and laboratory data collected for fishes sampled by boat electrofishing in the Sacramento-San Joaquin delta, CA. This data release includes all measured environmental parameters, body composition analyses, otoliths, and fish taxa included in the analysis.
Sample collection information and whole genome data for Greater and Gunnison Sage-grouse range generated in the Molecular Ecology Lab during 2015-2018 Sample collection information and whole genome data for Greater and Gunnison Sage-grouse range generated in the Molecular Ecology Lab during 2015-2018
This dataset contains sample collection information for whole genome sequences of Gunnison and Greater Sage-grouse. These data were collected in order to examine patterns of adaptive genetic variation in Greater and Gunnison Sage-grouse. The data is archived in GenBank at the following URL https://www.ncbi.nlm.nih.gov/bioproject/531321.
Genetic data and genetic network attributes for rangewide Greater Sage-grouse network constructed in 2018 (ver. 2.0, December 2022) Genetic data and genetic network attributes for rangewide Greater Sage-grouse network constructed in 2018 (ver. 2.0, December 2022)
Genetic networks can characterize complex genetic relationships among groups of individuals, which can be used to rank nodes most important to the overall connectivity of the system. Ranking allows scarce resources to be guided towards nodes integral to connectivity. The greater sage-grouse (Centrocercus urophasianus) is a species of conservation concern that breeds on spatially discrete...
Data maps of predicted raven density and areas of potential impact to nesting sage-grouse within sagebrush ecosystems of the North American Great Basin Data maps of predicted raven density and areas of potential impact to nesting sage-grouse within sagebrush ecosystems of the North American Great Basin
These data represent predicted common raven (Corvus corax) density (ravens/square-km) derived from random forest models given field site unit-specific estimates of raven density that were obtained from hierarchical distance sampling models at 43 field site units within the Great Basin region, USA. Fifteen landscape-level predictors summarizing climate, vegetation, topography and...
