Data

This dataset consists of sample descriptions and radiocarbon age data from Karluk Lake on Kodiak Island, Alaska; samples were analyzed at Northern Arizona University, Arizona Climate and Ecosystems Isotope Laboratory https://in.nau.edu/aceisotopelab/.

This data release provides radiochemistry data (210Pb and 137Cs) of two sediment cores, BC01 and BC02, collected during USGS Field Activity 2024-662-FA in 2024 in San Francisco Bay, California, U.S.A., off Alameda and Point Isabel, respectively.

California’s wildfires are setting historic records for length, size, and severity (Safford and others, 2022, Kreider and others, 2024). These wildfires are altering soil processes like infiltration rates and carbon cycling over increasingly large areas (Staley and others, 2017; Kelly and others, 2020; Baur and others, 2024; Dow and others, 2024). In northern California, it is unclear...

This U.S. Geological Survey data release is a collection of Raman spectra, electron probe microanalytical results, and images for burbankite [(Na,Ca)3(Sr,Ba,Ce)3(CO3)5] from the type locality at the Rocky Boy stock, Bears Paw Mountains, Montana. Burbankite was described by Pecora and Kerr (1953) for the first time from samples collected in the Bears Paw Mountains (in their publication...

A series of gold tube pyrolysis experiments (72 hrs, 300–600 °C) conducted on a graptolite-rich lower Paleozoic marine shale generated pyrolysis residues for a comprehensive evaluation of the molecular and structural variability of three types of graptolite periderm, namely granular, non-granular, and nodular graptolite. Raman spectroscopy in combination with organic petrology and field...

This USGS data release contains R models (R Core Team, 2020) for estimating 7Q10 and 30Q10 [lowest annual 7-day and 30-day average streamflow that occurs (on average) once every 10 years] statistics at ungaged locations in or adjacent to New York State excluding Long Island. Details on model development are available in Stagnitta and others (2025). basin_characteristics.csv - 224 basin

Data include the probability of persistence of 407 Ornate Chorus Frog (Pseudacris ornata) populations across the distribution, as well as the mean habitat suitability, mean winter precipitation, and proportion of the surface that is impervious within each buffered population. Data also include the probability of persistence of Ornate Chorus Frog populations when different buffer sizes...

The RCMAP (Rangeland Condition Monitoring Assessment and Projection) dataset quantifies the percent cover of rangeland components across western North America using Landsat imagery from 1985-2024. The RCMAP product suite consists of ten fractional components: annual herbaceous, bare ground, herbaceous, litter, non-sagebrush shrub, perennial herbaceous, sagebrush, shrub, tree, and shrub...

Manganese is a designated critical mineral, being industrially utilized for producing steel and batteries, including in the production of electric vehicles (Rozelle et al., 2021). The eastern United States hosts hundreds of manganese oxide mines that served steel production until their abandonment in the mid-twentieth century (Pegau, 1958). Many relict mines still feature accessible pits...

The USGS team measured base cations, aluminum (Al), iron (Fe), manganese (Mn), rare earth elements (REEs), dissolved organic carbon (DOC), major anions, and phosphorus (P) in eight streamwater grab (manual) samples during each of three high-flow events (E-1, E-2, E-3) at the forested headwater catchment W-9, Sleepers River, Vermont, USA. E-1 was a large fall rainstorm, E-2 was a multi...

The Rare Plant Occurrences geodatabase is an element occurrence data system with about 10,000 records of rare plant observations on the 6 northernmost California Channel Islands. It is a live database created with the purpose of bringing together in one space all discoverable historic and current information on the localities of about 180 rare and sensitive plants of the northern Channel...
