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.

Round goby detection by scuba divers’ visual assessments and environmental DNA in the Great Lakes, 2022 Round goby detection by scuba divers’ visual assessments and environmental DNA in the Great Lakes, 2022
This dataset is associated with an examination of environmental DNA (eDNA) from the invasive round goby (Neogobius melanostomus) in parallel with visual surveys of fish count and size conducted by scuba divers in four Great Lakes: Michigan, Huron, Erie, and Ontario. Round goby inhabits benthic areas, and it is known to have direct contact with the bottom substrate as it feeds on...
Coal Exploration Drill-Hole Data for Alaska, Colorado, Illinois, Iowa, Kansas, Missouri, Montana, North Dakota, Virginia, and Wyoming Coal Exploration Drill-Hole Data for Alaska, Colorado, Illinois, Iowa, Kansas, Missouri, Montana, North Dakota, Virginia, and Wyoming
Coal exploration drill-hole data from 5,037 wells located in Alaska, Colorado, Illinois, Iowa, Kansas, Missouri, Montana, North Dakota, Virginia, and Wyoming are provided in this data release. The wells are located in sixty-eight counties and were drilled between 1971 and 1981, primarily by Phillips Petroleum Company (Phillips). The hard-copy paper data were donated to the U.S...
U-Pb zircon geochronology data for Spinney Mountain and Guffey NW Geologic Maps, Park County, CO U-Pb zircon geochronology data for Spinney Mountain and Guffey NW Geologic Maps, Park County, CO
This data release includes laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) U-Pb zircon geochronology data from four samples collected from rock units located in the Spinney Mountain Quadrangle and the Guffey NW Quadrangle in Park County, Colorado. Samples were collected from gniess and granite rocks, and age data was used to support publication of updated maps by...
Occurrence, Rarity and Climate Sensitivity Index, and Components of 29 Fishes Native to the Pacific Northwest, USA Occurrence, Rarity and Climate Sensitivity Index, and Components of 29 Fishes Native to the Pacific Northwest, USA
These datasets include the components of and results from the Rarity and Climate Sensitivity Index (RCS) and occurrence records used to calculate the index for 29 stream fishes native to the Pacific Northwest (Washington, Idaho, Oregon) of the United States. The RCS is an index that ranks species’ intrinsic sensitivity to climate change based on their area of occurrence and climate niche...
Salinity Loads at 20-stations in the Colorado River Basin Salinity Loads at 20-stations in the Colorado River Basin
The U.S Geological Survey (USGS), in cooperation with the Bureau of Reclamation (Reclamation), prepares a biennial analysis of salt loading at 20 sites on the Colorado River and its tributaries in Colorado, Wyoming, New Mexico, Utah, and Arizona. These estimates can also be used by Reclamation to measure the effectiveness of the Colorado River Basin Salinity Control Program. Data are...
Plant community composition, abundance, phenology, and soil data from a four-year seasonal drought experiment followed by four years of recovery in a mixed grassland on the Colorado Plateau Plant community composition, abundance, phenology, and soil data from a four-year seasonal drought experiment followed by four years of recovery in a mixed grassland on the Colorado Plateau
These data were compiled for a study that investigated the effects of experimentally imposed seasonal droughts (cool season drought, warm season drought, ambient) and drought recovery on plant community dynamics in a mixed dryland ecosystem. In 2015, U.S. Geological Survey ecologists began recording vegetation and soil moisture data in 36 experimental plots which manipulated...
