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.

Ungulate Migrations of the Western United States, Volume 3
This is the data archive for the publication Ungulate Migrations of the Western United States, Volume 3 (Kauffman et al. 2022) and includes the collection of GIS map files that are mapped and described in the report. These map files are meant to provide a common spatial representation of the mapped migrations. This data release provides the means for ungulate migrations to be mapped and planned fo
Bias estimation for seven precipitation datasets for the eastern MENA region
Information on the spatio-temporal distribution of rainfall is critical for addressing water-related disasters, especially in the Middle East and North Africa's (MENA) arid to semi-arid regions. However, the availability of reliable rainfall datasets for most river basins is limited. In this study, we utilized observations from satellite-based rainfall data, in situ rain gauge observations, and
Reef-census Data from Buck Island Reef National Monument
In July of 2016, Florida Institute of Technology researchers, in collaboration with the U.S. Geological Survey (USGS), conducted reef-census surveys at 54 sites around Buck Island Reef National Monument, St. Croix, U.S. Virgin Islands. The sites are divided across two reef sectors (North and South) and three reef habitats (fore reef, reef crest, and back reef) (Figure 1). These data were used to e
Predicted consequences of detecting dreissenid mussel eDNA in Jordanelle Reservoir Utah, 2021
U.S. Geological Survey decision analysts and technical experts worked with representatives from the U.S. Bureau of Reclamation, Utah Division of Wildlife Resources, and Central Utah Water Conservancy District to predict the consequences of alternative actions following environmental DNA detections of dreissenid mussel eDNA in Jordanelle Reservor, Utah. This dataset provides the consequence and mod
Trends and a Targeted Annual Warning System for Greater Sage-Grouse in the Western United States (ver. 3.0, February 2024)
Greater sage-grouse (Centrocercus urophasianus) are at the center of state and national land use policies largely because of their unique life-history traits as an ecological indicator for health of sagebrush ecosystems. These data represent an updated population trend analysis and Targeted Annual Warning System (TAWS) for state and federal land and wildlife managers to use best-available science
Bumblebee Surveys in Montana, North Dakota, South Dakota, and Nevada, USA (ver. 2.0, April 2023)
Bumblebee community surveys used occupancy survey designs primarily across lands managed by the Bureau of Land Management (BLM) and Glacier National Park (GNP). They also include a few surveys in Nevada. These records represent timed surveys that were both successful and unsuccessful in detecting western bumblebees.
Radioanalytical Measurements on Samples From Submarine, Karstic Carbonate Features Along the West Florida Shelf
Relict karstic features, often referred to as blue holes, are common features along continental shelves that are underlain by carbonate rich sediments and/or rocks. Several of these features occur along the west-Florida shelf within the Gulf of Mexico, including the two mentioned in this data product: Amberjack Hole and Green Banana Sink (hereafter referred to as Green Banana). Scientists from U.S
Groundwater-Level Altitudes and Volatile and Semivolatile Organic Compound Concentrations at the Petro-Chemical Systems, Inc. (Turtle Bayou) Superfund Site, Liberty County, Texas, 2020
In 2020, the U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency, collected groundwater-level altitude data and water-quality samples from monitoring wells at the Petro-Chemical Systems, Inc. (Turtle Bayou) Superfund Site in Liberty County, Texas to evaluate the status of groundwater contamination at this previously remediated site. The dataset includes groundwater
Groundwater-quality data in the Butte-Sutter-Yuba Domestic-Supply Aquifer Study Unit, 2021: Results from the California GAMA Priority Basin Project
The U.S. Geological Survey collected groundwater samples from 38 wells used for domestic and small system drinking water supplies in Butte, Sutter, and Yuba counties of California during 2021. The wells were sampled for the Butte-Sutter-Yuba Domestic-Supply Aquifer Study Unit of the State Water Resources Control Board Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority Basin Proj
Laboratory and Field Data for a Performance Evaluation of the PhytoFind, an In-Place Phytoplankton Classification Tool
This data release presents the laboratory and field results of a performance evaluation conducted on the Turner Designs, Inc., PhytoFind, an in-place phytoplankton classification tool. The laboratory evaluation included tests that were designed to characterize PhytoFind performance under a range of conditions that may affect phytoplankton fluorescence and sensor response. Laboratory tests included
MODFLOW-6 model to update and extend the Los Angeles Coastal Plain Groundwater Model
The Los Angeles Coastal Plain (LACP) covers about 580 square miles and is the largest coastal plain of semiarid southern California. The LACP is heavily developed with mostly residential, commercial, and industrial land uses that rely heavily on groundwater for water supply. In 2010, the LACP was home to about 14 percent of California’s population and is also a major commercial and industrial hub.
Satellite precipitation estimates for selected locations in the Republic of the Marshall Islands
The Republic of the Marshall Islands (RMI) is a sovereign Small Island State in the tropical central North Pacific Ocean. RMI is a nation of more than thirty atolls and islands, most of which are inhabited, dispersed across an exclusive economic zone (EEZ) over 2 million square kilometers. This data release contains files of daily precipitation estimates beginning in 2001 for 23 inhabited sites in
