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.

Fish and Climate Change (FiCli) Database: Informing climate change adaptation and management actions for freshwater fishes
Inland fishes provide important ecosystem services to communities worldwide and are especially vulnerable to the impacts of climate change. Fish respond to climate change in diverse and nuanced ways, which creates challenges for practitioners of fish conservation, climate change adaptation, and management. Although climate change is known to affect fish globally, a comprehensive online, public dat
Early estimates of Annual Exotic Herbaceous Fractional Cover in the Sagebrush Ecosystem, USA, May 2020
The dataset provides an estimate of 2020 herbaceous mostly annual fractional cover predicted on May 1st with an emphasis on annual exotic grasses Historically, similar maps were produced at a spatial resolution of 250m (Boyte et al. 2019 https://doi.org/10.5066/P9ZEK5M1., Boyte et al. 2018 https://doi.org/10.5066/P9KSR9Z4.), but we are now mapping at a 30m resolution (Pastick et al. 2020 doi:10.33
Whole Rock Density, Magnetic Susceptibility, and Radiometric Measurements of a Rare Earth Element Terrane, Southeastern Mojave Desert.
Efforts by the USGS to characterize regional geology of the southeastern Mojave Desert near Mountain Pass, California, include 1,061 rock samples collected along the southern California/Nevada border. Rock property measurements include density, magnetic susceptibility, and radiometric concentrations to understand structural and geophysical relationships associated with rare earth element mineral d
Historical Shorelines for Fire Island and Great South Bay, New York (1834 to 1875): Georeferenced Topographic Sheets and Vector Digital Data
Topographic sheets (t-sheets) produced by the National Ocean Service (NOS) during the 1800s provide the position of past shorelines. The shoreline data can be vectorized into a geographic information system (GIS) and compared to modern shoreline data to calculate estimates of long-term shoreline rates of change. Many t-sheets were scanned and digitized by the National Oceanic and Atmospheric Admin
Data Release for the 2018 U.S. Geological Survey - California Geological Survey Fault-Imaging Surveys Across the Hollywood and Santa Monica Faults, Los Angeles County, California
We acquired multiple types of controlled-source seismic data across the Hollywood Fault in Hollywood, Calif., and the Santa Monica Fault in Beverly Hills, Calif., in May and June of 2018. We acquired two separate profiles across the Hollywood Fault, and from those data we can evaluate multiple seismic datasets and calculate seismic models including guided-wave data, tomographic VP data, tomographi
Data and Shapefiles for the Potentiometric Surface of the South Coast Aquifer and Hydrologic Conditions in the Santa Isabel area, Puerto Rico, March-April 2014
A groundwater-level survey and reconnaissance of the hydrologic conditions in the coastal alluvial plain of southern Puerto Rico was conducted by the U.S. Geological Survey, in cooperation with the Puerto Rico Department of Natural and Environmental Resources. The objective of the field survey was to delineate the potentiometric surface of the coastal alluvial aquifer between the Rio Descalabrado
Surrogate regression models for computation of time series suspended-sediment concentrations at Muddy Creek above Paonia Reservoir, Anthracite Creek above mouth near Somerset, and North Fork Gunnison below Raven Gulch near Somerset, Colorado
This model archive summary documents the surrogate regression model used to compute suspended-sediment concentrations at Muddy Creek above Paonia Reservoir, CO, USGS site number 385903107210800. The methods used follow U.S. Geological Survey (USGS) guidance as referenced in relevant Office of Surface Water Technical Memorandum (TM) 2016.07 and Office of Water Quality TM 2016.10, and USGS Technique
Data Sets from the National Crude Oil Spill Fate and Natural Attenuation Research Site near Bemidji, Minnesota, USA (ver. 3.0, March 2020)
This version supersedes the previous version of this data release: Trost, J.J., Krall, A.L., Baedecker, M., Cozzarelli, I.M., Herkelrath, W.N., Jaeschke, J.B., and Bekins, B.A., 2018, Historical data sets including inorganic and organic chemistry of water, oil, and sediments, aquifer hydraulic conductivity, and sediment grain size distribution at the National Crude Oil Spill Fate and Natural Atten
Select borehole data for Anza basin, Anza, CA
Borehole log number, State Well Number, location, construction information, and any wells tests performed on select wells from the Anza basin, Anza, CA. Also includes a lithologic data for a sub-set of borehole logs identified based on best coverage and representation of data within the study area.
Datasets from Groundwater-Quality and Select Quality-Control Data from the National Water-Quality Assessment Project, January through December 2016, and Previously Unpublished Data from 2013 to 2015
Groundwater-quality data were collected from 648 wells as part of the National Water-Quality Assessment Project of the U.S. Geological Survey National Water-Quality Program and are included in this report. Most of the wells (514) were sampled from January through December 2016 and 60 of them were sampled in 2013 and 74 in 2014. The data were collected from seven types of well networks: principal a
The North American Breeding Bird Survey, Analysis Results 1966 - 2018
This data product consists of a database of population change and abundance estimates for North American birds, estimated from North American Breeding Bird Survey (BBS) data. Data are presented for 548 species of birds in 4 spreadsheets containing trend estimates and annual indices for 2 time periods. Estimates are derived for each species using the 1 of 4 alternative models, and a cross-validatio
Data for the Estimation of Regional Flow-Duration Curves for Indiana and Illinois (ver. 3.0, December 2021)
Digital datasets were used to develop basin characteristics whose values are used in multiple regression equations and tested for the use in predicting flow-duration curves (FDCs) in ungaged areas of Illinois and Indiana. Several basin characteristics are easily derived from StreamStats (https://streamstats.usgs.gov/ss/) basin delineations themselves, such as basin area and basin centroid. Other
