Northern Lake Michigan Gillnet Assessment 1998-2024 Northern Lake Michigan Gillnet Assessment 1998-2024
Annual spring (May) and fall (late October through early November) gillnet assessment surveys were conducted by researchers at the USGS Great Lakes Science Center (GLSC) in northern Lake Michigan, including the Northern Refuge, between 1998-2024. Total length, weight, sex, maturity, and sea lamprey wounds were recorded for each lake trout and burbot caught in the gill nets. Lake trout...
Avian Point-Count Data from Boreal Alaska and Maps of Predicted Population Density for Lesser Yellowlegs, Olive-sided Flycatcher, and Rusty Blackbird, 2001-2020 Avian Point-Count Data from Boreal Alaska and Maps of Predicted Population Density for Lesser Yellowlegs, Olive-sided Flycatcher, and Rusty Blackbird, 2001-2020
This data package contains 1) field data and 2) predicted distributions of three species of boreal-nesting birds in interior Alaska: Lesser Yellowlegs (Tringa flavipes), Olive-sided Flycatcher (Contopus cooperi), and Rusty Blackbird (Euphagus carolinus). The data are compiled from several monitoring programs: Alaska Landbird Monitoring Survey, Alaska Off-road Point-count Program, Susitna...
Nitrate and Chloride Data for evaluating Decadal Changes in Groundwater Nitrate and Chloride Data for evaluating Decadal Changes in Groundwater
The U.S. Geological Survey’s National Water Quality Network (NWQN) is the primary source of data to monitor trends in contaminants in groundwater in the United States. However, other data sources are available to evaluate trends. The Water Quality Portal (WQP) and the National Groundwater Monitoring Network (NGWMN) portal provide data that can be used for groundwater quality trends in...
Topographic data, aerial imagery, and GPS data collected during uncrewed aircraft system (UAS) operations at Sesuit Marsh, Dennis, Massachusetts, August 12, 2024 Topographic data, aerial imagery, and GPS data collected during uncrewed aircraft system (UAS) operations at Sesuit Marsh, Dennis, Massachusetts, August 12, 2024
Small Uncrewed Aircraft Systems (sUAS) were used to collect aerial remote sensing data over Sesuit Marsh in Dennis, MA. Raw data from aerial surveys include aerial images from natural color (RGB) and multispectral cameras and raw lidar data. These datasets were processed to produce high resolution digital elevation models (DEM), image mosaics, and lidar point clouds (LPC) to provide...
Observation of unusual neonate-clustering behavior observed post molting on maternal New River Crayfish in mesocosms Observation of unusual neonate-clustering behavior observed post molting on maternal New River Crayfish in mesocosms
Cambarus chasmodactylus (New River Crayfish) is one of the largest crayfish species occurring in the Appalachian Mountains and occupies a niche similar to several highly imperiled crayfishes within the same region.Little is known about the behavior and relationship between female crayfishes of this species and their young, and this unexpected clustering behavior of neonates about the...
Wildlife locations in select areas, 2014-2023 Wildlife locations in select areas, 2014-2023
USGS researchers surveyed talus patches across the western USA, in conjunction with numerous partners during 2014-2023, inclusive. Data are locations at which wildlife species of statutory interest to state and federal partners were detected, as well as covariate data associated with each location.
Snow Measurements in Specific Canopy Structure and Aspect Regimes for the 2025 Water Year, North of Coal Creek, San Juan Mountains, Colorado, USA Snow Measurements in Specific Canopy Structure and Aspect Regimes for the 2025 Water Year, North of Coal Creek, San Juan Mountains, Colorado, USA
This data release includes snow depth and snow water equivalent (SWE) for the water year 2025 during ten separate field campaigns that took place between late December and late May. The field area is comprised of 703 surveyed points in, on the perimeter of, and surrounding six flat field (‘no_slope’) forest openings, four northern hillslope aspect (‘north_slope’) forest openings and four...
X-ray diffraction data for the 0-2 cm horizons of marine sediment cores and a mineral concretion near waste barrels in the San Pedro Basin of the Southern California Borderland X-ray diffraction data for the 0-2 cm horizons of marine sediment cores and a mineral concretion near waste barrels in the San Pedro Basin of the Southern California Borderland
Marine sediment push cores and one mineral concretion were collected near waste barrels in the San Pedro Basin of the Southern California Borderland in the Pacific Ocean using a remotely operated vehicle during the Schmidt Ocean Institute research cruise FK210726 onboard the R/V Falkor in 2021. Dried sediment samples of the 0-2 centimeter horizon of the cores and the mineral concretion...
USGS National and Global Oil and Gas Assessment Project—United States Federal Lands Oil and Gas Resource Allocations: Federal Lands Fact Sheet Data Tables USGS National and Global Oil and Gas Assessment Project—United States Federal Lands Oil and Gas Resource Allocations: Federal Lands Fact Sheet Data Tables
The U.S. Geological Survey (USGS) assesses potential volumes of undiscovered, technically recoverable oil and gas resources in the onshore and state water provinces of the United States. Following the quantitative oil and gas assessments, allocations of undiscovered oil, gas, and natural gas liquid resources are calculated for land entities in each assessment unit where surface ownership...

This dataset includes the underlying data for each figure and table, as well as the raw model output data, for the publication: Modeling interconnected minerals markets with multicommodity supply curves: examining the copper-cobalt-nickel system, published in Nature Communications.
Bedrock geologic map database for the Aztec 1-degree x 2-degree quadrangle, northern New Mexico and southern Colorado Bedrock geologic map database for the Aztec 1-degree x 2-degree quadrangle, northern New Mexico and southern Colorado
This data release presents geologic map data for the bedrock geology of the Aztec 1-degree by 2-degree quadrangle, New Mexico. Geologic mapping incorporates new interpretive contributions and compilation from published geologic map data sources primarily ranging from 1:24,000 to 1:50,000 scale. Much of the geology incorporated from published geologic maps is adjusted based on digital...
Electron Microprobe and 40Ar/39Ar data from the East Derby Shear Zone, Connecticut Electron Microprobe and 40Ar/39Ar data from the East Derby Shear Zone, Connecticut
