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.

Land Change Monitoring, Assessment, and Projection (LCMAP) Collection 1.3 Annual Land Cover and Land Cover Change Validation Tables (1985–2021) for the Conterminous United States
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 resolutio
Water-Quality, Bed-Sediment, and Invertebrate Tissue Trace-Element Concentrations for the Clark Fork River and Tributaries in the Upper Clark Fork Basin, Montana, October 2020-September 2021
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 monitor trace e
Tracking Data for Bar-tailed Godwits (Limosa lapponica)
This metadata document describes the data contained in the "rawData" folder of this data package. This data package contains all data collected by the Argos System from 63 satellite transmitters attached to Bar-tailed Godwits on their breeding range in arctic and western Alaska, 2005-2010. Five data files are included in the "rawData" folder of this data package. Two data files (with identical con
Radiocarbon Data for Tree Ring Samples from Girdwood, Alaska
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.
Comparisons from an Aqualog Fluorometer Standardized to Quinine Sulfate Equivalents (QSE) with Excitation (ex) and Emissions (em) Equivalent to Fluorescence of Dissolved Organic Matter (fDOM) Sensors from Multiple Manufacturers
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 quinine sul
Molecular Detection and Characterization of Highly Pathogenic H5N1 Avian Influenza Viruses in Wild Birds Inhabiting Western Alaska Provides Evidence for Three Independent Viral Introductions
This data set describes three independent viral introductions of Highly pathogenic H5N1 avian influenza viruses into Alaska.
Geospatial Dataset of Water-Table and Potentiometric-Surface Altitudes in the Upper Glacial, Magothy, and Lloyd Aquifers of Long Island, New York, March–April 2006
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 across Long Isl
Geospatial Dataset of Water-Table and Potentiometric-Surface Altitudes in the Upper Glacial, Magothy, and Lloyd Aquifers of Long Island, New York, April-May 2010
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.
