Landsat 8 and Landsat 9 Earth imaging acquisitions are guided by their respective Long Term Acquisition Plan (LTAP), that has been established for each satellite observatory. The LTAP is structured around the Worldwide Reference System-2 (WRS-2) grid, which partitions Landsat swath imaging of the Earth into ~185 × 180 km scenes using a path/row notation. These WRS-2 scenes represent the

This data release contains geochemical and petrographic data for the Eagle Ford Group in the USGS Gulf Coast #3 (GC-3) core and the Mowry Shale and Frontier Formation in the Nerd Gas Co. Oil Mountain 1-16 (OM-1-16) core. This dataset includes newly generated kerogen elemental chemistry, iron speciation, organic biomarkers, and vitrinite reflectance. This data compliments and is in...

These data were compiled to show where significant river-sourced aeolian sediment deposits are present along the Colorado River downstream of Glen Canyon Dam in the Grand Canyon from Lee’s Ferry to the Diamond Creek confluence located 225 miles downstream. These deposits represent 118 active aeolian dunefields and were created by the Grand Canyon Monitoring & Research Center using field...

A reach of the Sacramento River near Glenn, California, was selected as a field site to test the performance of a software-defined radar (SDRadar) developed by the University of Southern California. The SDRadar can be deployed from an uncrewed aircraft system (UAS) and is designed to measure river depth. This data release contains measurements of river depth collected with two different...

Data represent physical (water quality) and biological (fish, macroinvertebrate, and vegetation community) collections as indicators for Pool 1A and the Maankiki Marsh North and South units at the Shiawassee National Wildlife Refuge in Saginaw, MI, USA. The Maankiki North and South units were recently reconnected to the Shiawassee River in 2018, whereas Pool 1A represents a historically

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...

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...

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...

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...

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...

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.

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...
