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.

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...
