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...

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...
