Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Data Release for Luminescence: Late Holocene rupture history of the Ash Hill Fault, Eastern California Shear Zone, and the potential for seismogenic strain transfer between nearby faults Data Release for Luminescence: Late Holocene rupture history of the Ash Hill Fault, Eastern California Shear Zone, and the potential for seismogenic strain transfer between nearby faults
The following report summarizes the dating results from sedimentary deposits exposed by soil pits in Panamint Valley, CA. Within this report, we detail the methodology used by the USGS Luminescence Geochronology Laboratory to obtain ages including sample preparation methods, luminescence measurement, equivalent dose determination, and dating-related calculations.
Data Release for Luminescence: Paleoseismic liquefaction associated with Holocene earthquakes on the Wallula Fault zone, Southeast Washington, USA Data Release for Luminescence: Paleoseismic liquefaction associated with Holocene earthquakes on the Wallula Fault zone, Southeast Washington, USA
Observations of widespread liquefaction and stratigraphic and structural relationships in a trench across an ambiguous scarp are used to constrain the timing of Holocene earthquakes on the northwest-striking Wallula fault zone in southeast Washington and Oregon. Additional observations and age constraints from OSL analysis of samples collected from large-scale liquefaction features that...
Atlantic and Gulf Coast Sandy Coastline Topo-Bathy Profile and Characteristic Database Atlantic and Gulf Coast Sandy Coastline Topo-Bathy Profile and Characteristic Database
Seamless topographic-bathymetric (topo-bathy) profiles and their derived morphologic characteristics were developed for sandy coastlines along the Atlantic and Gulf coasts of the United States. The topo-bathy profiles are published as a database in the Hierarchical Data Format version 5 (HDF5) which contain cross-shore distance coordinates, Universal Transverse Mercator (UTM) coordinate...
Time to First Detection of Northwestern Pond Turtles and Red-eared Sliders by Bait Type in the Sacramento Valley, California, 2018 Time to First Detection of Northwestern Pond Turtles and Red-eared Sliders by Bait Type in the Sacramento Valley, California, 2018
These data provide the time to first detection in days of Northwestern Pond Turtles (Actinemys marmorata) and Red-eared Sliders (Trachemys scripta elegans) by trapping location and bait type in the Sacramento Valley, California, in 2018. Bait types evaluated include sardines and dry cat food. Only location, species, and bait type combinations that resulted in captures are included. These...
