Data

This data release contains elemental concentration data from the reanalysis of 13,930 archived stream-sediment sample and associated stream sediment reference material and 968 archived rock samples and associated rock reference material. All archived material was from samples that were collected in Alaska. Samples were retrieved from the USGS Mineral Program's sample archive in Denver, CO. Sample

The USGS Protected Areas Database of the United States (PAD-US) is the nation's inventory of protected areas, including public land and voluntarily provided private protected areas, identified as an A-16 National Geospatial Data Asset in the Cadastre Theme ( https://ngda-cadastre-geoplatform.hub.arcgis.com/ ). The PAD-US is an ongoing project with several published versions of a spatial database i

Airborne geophysical surveys were acquired in March 2018 and May 25 through August 7, 2021 using a helicopter-based platform. These surveys were collected along 10,706 line-kilometers (line-km) within selected areas of the Mississippi Alluvial Plain (MAP) and the Chicot Aquifer System in the southeastern United States. The airborne geophysical surveys include electromagnetic, magnetic, and radiome

This data release contains phytoplankton data and vertical profile measurements of water quality and light in oligotrophic (low nutrient) lakes within the Adirondack Park, New York State. Data were collected between June and October 2021 at five lakes. Four lake locations (Nearshore, Open Water, Layer, Bloom) were sampled representing one of four sample types (Bottom Sediment, Surface Water, Bloom

Crystalline graphite is a primary material in lithium-ion battery anodes which are essential in moving towards green energy. Forecasts for 2040 anticipate an order of magnitude increase in graphite demand driven by sustainable development policies to reduce carbon emissions. Domestic production of graphite ceased in the 1980s after a steady decline post-World War I, meaning the United States relie

The 2018 eruption from the lower East Rift Zone of Kīlauea volcano, on the Island of Hawaiʻi, was one of the most significant and destructive events on the volcano in the past 200 years (Neal and others, 2019; Patrick and others, 2020; Anderson and others, 2023; Mulliken and others, 2024). Between May and September of that year, 24 fissures opened on the lower flank of the volcano, producing lava

Since 1993 the U.S. Geological Survey (USGS) has worked with the Alaska Department of Transportation and Public Facilities (ADOT&PF) to provide hydraulic assessments of scour for bridges throughout Alaska. As part of this effort, repeat channel cross section surveys, or channel soundings, have been collected at either the upstream or downstream side of bridges on an annual or as needed basis. Stre

These data are the results of a spatially interpolated integrated population model (SIIPM) fit to count and demographic data collected from populations of Greater Sage-grouse (Centrocercus urophasianus; hereafter, sage-grouse) located in Nevada, U.S.A. during 2013-2021. We used a novel framework, using integrated population models (IPMs), to express demographic relatedness among sampled and unsamp

The data set includes the daily streamflow predictions from (Long Short-Term Memory) LSTM models for 45 basins (27 basins in New England region and 18 basins in Great Basin region) in contrasting hydroclimate regions (water-limited Great Basin region and energy-limited New England region) in the United States. Also, the shapefiles of study basins and hydroclimate regions, and data to support the s

This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over parts of Montana in the vicinity of the Boulder Batholith. The airborne survey was jointly funded by the Earth Mapping Resources Initiative and Kennecott Exploration Company. The survey was designed to meet complementary needs related to geologic mapping and characterization of m

As part of the Triangle Area Water Supply Monitoring Project, the U.S. Geological Survey conducted a study to evaluate the occurrence and distribution of phytoplankton, taste-and-odor compounds, and cyanotoxin occurrence in four water-supply reservoirs in the Triangle area of North Carolina. This data release contains the associated data described in the Scientific Investigations Report, "Phytopla

This data release includes multiple datasets obtained during the study of north-facing fault scarps along the Seattle fault zone. It includes geochronological data and field measurements from the Vasa Park trench (47.576618°, -122.119524°) near Bellevue, WA, and the Rose Hip trench (47.597°, -122.535°), Lyle Beach terrace site (47.597,-122.542), and Mill Pond site (47.597,-122.525) on south Bainbr
