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.

Lek Disturbance Buffer Analysis data, Western Colorado, Derived from Gunnison Sage Grouse Location Data 2010 - 2014 Lek Disturbance Buffer Analysis data, Western Colorado, Derived from Gunnison Sage Grouse Location Data 2010 - 2014
This data release consists of three files (Crawford_and_WGB_Location_Data_S1.csv, Lek_Dist_S2.csv, and Home_Range_Area_S3.csv). The first data set represents specifics about each GPS location representing temporal and spatial relationships used in our analysis including the Month, day and year and local time each location was collected along with distance between locations, elevation in...
SHRIMP U-Pb geochronologic data for zircon and titanite from Mesoproterozoic rocks of the St. Francois Mountains terrane, southeast Missouri, U.S.A. SHRIMP U-Pb geochronologic data for zircon and titanite from Mesoproterozoic rocks of the St. Francois Mountains terrane, southeast Missouri, U.S.A.
These data are for a regional geochronologic study of Mesoproterozoic rocks in the St. Francois Mountains, southeast Missouri. Zircon, plus one sample of titanite, from fifty samples of metaigneous rocks were dated by sensitive high resolution ion microprobe (SHRIMP).
Concentrations of Pesticide, Pharmaceutical, and Organic Wastewater Contaminants from a Multi-Regional Assessment of Wadeable USA Streams, 2014-17 Concentrations of Pesticide, Pharmaceutical, and Organic Wastewater Contaminants from a Multi-Regional Assessment of Wadeable USA Streams, 2014-17
Human-use pharmaceutical, pesticide, and wastewater indicator compounds were analyzed at the U.S. Geological Survey, National Water Quality Laboratory, Denver, Colorado, in wadeable streams in 4 Regional Stream Quality Assessments: Northeast (NESQA), Southeast (SESQA), Pacific Northwest (PNSQA) and California (CSQA). Multiple (with few exceptions) samplings occurred at each site, during...
Genetic variation in hoary bats (Lasiurus cinereus) assessed from archived samples Genetic variation in hoary bats (Lasiurus cinereus) assessed from archived samples
Hoary bats are among the bat species most commonly killed by turbine strikes in the midwestern United States. The impact of this mortality on species census size is not understood, due in part to the difficulty of estimating population size for this highly migratory and elusive species. Genetic effective population size (Ne) could provide an index of census population size if other...
National Assessment of Hurricane-Induced Coastal Erosion Hazards National Assessment of Hurricane-Induced Coastal Erosion Hazards
These datasets contain information on the probabilities of hurricane-induced erosion (collision, inundation, and overwash) for each 1-km section of the United States sandy open-ocean coastline for category 1-5 hurricanes. The analysis is based on a storm-impact scaling model (Sallenger, 2000; https://www.jstor.org/stable/4300099) that uses observations of beach morphology combined with
Model of groundwater flow, gas migration, and reactive transport in the Virgin River Basin, SW Utah Model of groundwater flow, gas migration, and reactive transport in the Virgin River Basin, SW Utah
To better understand the possible risks posed to shallow groundwater resources by geologic carbon sequestration (GCS), a multi-scale numerical modeling approach was invoked using the TOUGHREACT code from Lawrence Berkeley National Laboratory. The code solves coupled equations representing conservation of mass and energy on a finite difference grid to simulate multiphase, multicomponent...
