Ambystomatid salamander population and breeding pond habitat data for the Delaware Water Gap National Recreation Area (2001 - 2003) Ambystomatid salamander population and breeding pond habitat data for the Delaware Water Gap National Recreation Area (2001 - 2003)
This database contains breeding pond use data (i.e., egg mass and larval abundance counts) of three ambystomatid salamander species (Spotted salamander, Jefferson salamander, and marbled salamander) collected from 200 individual aquatic habitats (ponds, wetlands, and impoundments) in the Delaware Water Gap National Recreation. Data were collected between the years 2001 and 2003. The...
Calibration Coefficients for the U.S. Geological Survey National Crustal Model and Depth to Water Table Calibration Coefficients for the U.S. Geological Survey National Crustal Model and Depth to Water Table
The U.S. Geological Survey National Crustal Model (NCM) is being developed to include spatially varying estimates of site response in seismic hazard assessments. Primary outputs of the NCM are continuous velocity and density profiles from the Earth's surface to the mantle transition zone at 410 km depth for each location on a 1-kilometer grid across the conterminous United States...
Wild lake trout (Salvelinus namaycush) diets from annual Lake Huron fall bottom trawl surveys (2008-2017) Wild lake trout (Salvelinus namaycush) diets from annual Lake Huron fall bottom trawl surveys (2008-2017)
Diet analyses were performed on juvenile lake trout (Salvelinus namaycush) captured by bottom trawl during annual USGS Great Lakes Science Center demersal fish community surveys in mid-October to mid-November 2008?2017 in Lake Huron. This dataset contains lake trout capture information (e.g., location, depth) and diet item data (taxa consumed and their associated lengths).
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...
