Data Releases

A validation assessment of Land Cover Monitoring, Assessment, and Projection Collection 1.3 annual land cover products (1985–2021) for the Conterminous United States was conducted with an independently collected reference dataset. Reference data land cover attributes were assigned by trained interpreters for each year of the time series (1984–2021) to a reference sample of 26,971 Landsat

Water, bed sediment, and invertebrate tissue were sampled in streams from Butte to near Missoula, Montana (MT), as part of a long-term monitoring program within the Upper Clark Fork Basin. The sampling program was completed by the U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency, to characterize aquatic resources in the Upper Clark Fork Basin and...

One of the subspecies, Limosa lapponica baueri, nests in Alaska and spends the nonbreeding season in New Zealand and eastern Australia whereas L.l.menzbieri nests in Siberia and spends the nonbreeding season in western Australia. Child Item 1: "Argos Satellite Tracking Data for Bar-tailed Godwits (Limosa...

This dataset consists of sample details and radiocarbon age data of tree-ring samples collected near Girdwood, Alaska, and analyzed at the National Ocean Sciences Accelerator Mass Spectrometry Facility.

GRAPES.jl is a Julia-language code for earthquake early warning. GRAPES.jl implements the GRAph Prediction of Earthquake Shaking (GRAPES) algorithm using graph neural networks. The GRAPES.jl package provides code for EEW ground motion predictions.

Here, we present the results supporting Table 2 in Field Techniques for Fluorescence Measurements Targeting Dissolved Organic Matter, Hydrocarbons, and Wastewater in Environmental Waters: Principles and Guidelines for Instrument Selection, Operation and Maintenance, Quality Assurance, and Data Reporting. Table 2 shows comparisons from an Aqualog 800 benchtop fluorometer standardized to...

This data set describes three independent viral introductions of Highly pathogenic H5N1 avian influenza viruses into Alaska.

This data release contains geospatial data defining estimates of the depth to water and water-table altitude in the upper glacial and Magothy Aquifers, the potentiometric surface of the confined Magothy and Jameco Aquifers, and the potentiometric surface of the Lloyd and North Shore Aquifers on Long Island, New York. Estimates are based on 502 water-level measurements made in wells...

This U.S. Geological Survey (USGS) data release contains results from the 2020 and 2021 geomorphic survey of North Fork Eagle Creek, New Mexico. Both geomorphic surveys were conducted by the USGS, in cooperation with the Village of Ruidoso, New Mexico, and are the last set of surveys in a planned series of five annual geomorphic surveys of the stream reach located between the North Fork...

This U.S. Geological Survey Data Release provides water-quality data collected during 1-week and 2-week nutrient studies beginning on February 22, May 17, and July 26 located in the Caloosahatchee River at the S-79 water-control structure. For each study period, 12 fiberglass tanks were suspended in the river using three floating cradles with each cradle holding four tanks. Each tank was...

This data release publishes datasets of historical aerial photograph orthomosaics covering areas within and surrounding Lassen Volcanic National Park, California. The historical imagery provides a high-resolution, spatially contiguous record of the park’s landscape across six dates ranging from 1941-2004. A total of 990 hard-copy aerial photographs taken in 1941, 1952, 1966, 1973, 1998...
