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.

Database of Riparian Floodplain Boundaries for the San Carlos and Gila Rivers on the San Carlos Apache Reservation and Upper Gila River Watershed (1935 - 2021) Database of Riparian Floodplain Boundaries for the San Carlos and Gila Rivers on the San Carlos Apache Reservation and Upper Gila River Watershed (1935 - 2021)
We developed this spatial database of historic and current floodplains to analyze trends in vegetation conditions, identify areas more at risk of degradation, and assess the relationship between riparian vegetation dynamics and climate conditions.Our study area is the riparian areas along the San Carlos River and Gila River within the San Carlos Apache Reservation and the Upper Gila...

Geospatial files and tabular exposure estimates of sinkhole susceptibility for counties in the conterminous United States for current conditions and projections for the years 2070-2079 - Overview Geospatial files and tabular exposure estimates of sinkhole susceptibility for counties in the conterminous United States for current conditions and projections for the years 2070-2079 - Overview
These datasets support the conclusions in the journal article entitled "Current and future sinkhole susceptibility in karst and pseudokarst areas of the conterminous United States" as described in the abstract below: Sinkholes in karst and pseudokarst regions threaten infrastructure, property, and lives. We mapped closed depressions in karst and pseudokarst regions of the conterminous...
Biological Indicators and Mercury Concentrations in Smallmouth Bass Biological Indicators and Mercury Concentrations in Smallmouth Bass
Biological indicators including morphometric (length, weight), age, sex and health indicators including organismal (health assessment index, condition factor), organ (hepatosomatic index, gonadosomatic index), cellular (intersex, parasite density, macrophage aggregate density), subcellular (plasma vitellogenin, estradiol, testosterone, 11-keto testosterone) and molecular (hepatic...
Imaging Flow Cytometry Data for Live and Preserved Phytoplankton Samples from Owasco and Seneca Lakes, Finger Lakes Region, New York, 2020 Imaging Flow Cytometry Data for Live and Preserved Phytoplankton Samples from Owasco and Seneca Lakes, Finger Lakes Region, New York, 2020
This U.S. Geological Survey (USGS) data release contains phytoplankton classification and enumeration results from near-surface samples analyzed by imaging flow cytometry and collected as part of a harmful algae bloom (HAB) monitoring study conducted in collaboration with the New York State Department of Environmental Conservation (NYSDEC). Samples were collected biweekly from monitoring...
Gravity, aeromagnetic, magnetic potential, and physical property data of the Bartlett Springs fault zone and surrounding areas, California Gravity, aeromagnetic, magnetic potential, and physical property data of the Bartlett Springs fault zone and surrounding areas, California
This data release contains principal facts of gravity measurements collected by the U.S. Geological Survey in 2020-2022, a compilation of existing and new density and magnetic susceptibility data, and gridded magnetic and magnetic potential data of the Bartlett Springs Fault Zone and surrounding areas, northern California. These data support modeling of gravity and magnetic anomalies to
Modeled Pacific salmon escapement biomass and nutrient and contaminant concentrations across western North America, 1976-2015 (version 2.0, October 2024) Modeled Pacific salmon escapement biomass and nutrient and contaminant concentrations across western North America, 1976-2015 (version 2.0, October 2024)
The data contain yearly modeled estimates of Pacific salmon escapement (in annual metric tons of wet mass) from 1976 to 2015 across four regions of western North America. A second data file contains modeled estimates of contaminant or nutrient concentrations in Pacific Salmon. The modeled estimates were derived from Bayesian generalized linear models (contaminant or nutrient...

This dataset includes genotypes and individual-based assignment tests for 1394 Atlantic Sturgeon selected for assignment by the National Marine Fisheries Service to meet management requirements under the Endangered Species Act.
Bathymetric and Topographic Surveys at Select Alaska Highway Bridges, 2023 Bathymetric and Topographic Surveys at Select Alaska Highway Bridges, 2023
In July 2023, the U.S. Geological Survey Alaska Science Center (USGS ASC) and the USGS Idaho Water Science Center (IDWSC), in cooperation with Alaska Department of Transportation and Public Facilities (AKDOT & PF), completed bathymetric and topographic surveys at four highway bridge structures using multibeam bathymetry and boat-mounted Light Detection and Ranging (LiDAR). The National...
DSWE_GEE v1.0.0 DSWE_GEE v1.0.0
Code for implementation of the Dynamic Surface Water Extent algorithm in Google Earth Engine. Multiple scripts allow the creation of single-scene or composited Dynamic Surface Water Extent (DSWE) images from Landsat and MODIS data. All code is written for use in the JavaScript API.
High-resolution seismic imaging data acquired in 2021 across a trace of the San Andreas Fault at Mee Ranch, Monterey County, California High-resolution seismic imaging data acquired in 2021 across a trace of the San Andreas Fault at Mee Ranch, Monterey County, California
In April of 2021, the U.S. Geological Survey conducted a high-resolution seismic survey at Mee Ranch in Monterey County, California. Both passive- and active-source seismic data were acquired using DTCC SmartSolo 3-component nodal seismograph systems ("nodes"), which continuously recorded data at rates up to 2000 samples per second. For passive-source acquisition, a 6x5 grid of nodes was...
High-resolution seismic imaging data acquired in 2021 across the West Winters Fault, Great Valley Fault System at Bigelow Hills, Yolo County, California High-resolution seismic imaging data acquired in 2021 across the West Winters Fault, Great Valley Fault System at Bigelow Hills, Yolo County, California
In June of 2021, the U.S. Geological Survey conducted a high-resolution seismic survey at Winters, California. Seismic data were acquired using a DTCC SmartSolo 3-component nodal seismograph system ("node"), which continuously recorded at 2000 samples per second. Nodes were deployed 5 meters apart from west-southwest to east-northeast to create an approximately 800-m-long linear profile...
