Data

This dataset provides information on aquatic invertebrate composition from ponds (n = 16; surface area 0.02 km2) and lakes (n =16, surface area > 0.10 km2) on the central Arctic Coastal Plain of Alaska. Ponds and lakes were selected for sampling as part of a larger study of Arctic water body food webs. Details on the study area and findings are published in Laske et al. 2018 and Laske...

Aquatic reflectance data from Sentinel-2 satellite imagery is paired with continuous water quality measurements across the Delaware, Illinois, Trinity, Upper Colorado, and Willamette River basins in the United States from July 2015 through September 2024. The dataset contains a zipped file (Matched_WQ_S2.zip) containing two csvs of matched continuous colored dissolved organic matter...

At least 28 rhyolitic lava flows, domes, and tuffs erupted within Yellowstone caldera following its formation 631 ka. Understanding the timing of intracaldera eruptions is essential for characterizing natural hazards posed by Yellowstone volcano. We present 40Ar/39Ar eruption ages for the Mallard Lake Member and Central Plateau Member of the Plateau Rhyolite, which comprise products from...

These data are from a Distributed Acoustic Sensing (DAS) experiment in Arcata, CA, that was conducted jointly by the U.S. Geological Survey, Cal Poly Humboldt University, and Luna Inc. A Luna QuantX DAS interrogator was installed in the Arcata Police Station and connected to a fiber owned by Vero Communications that runs from Arcata to Eureka (Figure 1). The interrogator was installed on...

The U.S. Geological Survey (USGS) Coastal and Marine Hazards and Resources Program has actively collected geophysical and sedimentological data in the northern Gulf of America (Gulf of Mexico) for several decades, including shallow subsurface data in the form of high-resolution seismic reflection profiles (HRSP). Prior to the mid-1990s, most HRSP data were collected in analog format as...

The dataset contains the gastrointestinal contents of 275 Argentine black and white tegus (Salvator merianae) collected between 2016 and 2021 from two geographically isolated populations in Florida: one in Miami-Dade County, established around 2011, and another in Charlotte County, established in 2018. Dietary analysis revealed a broad spectrum of consumed items, including vertebrates

Ar/Ar data are for 12 samples that record the eruption age of tephra. The geochronology provides time constraints for the ages of tephra and interbedded sediments and fossils from Kenya and Ethiopia. Samples were collected by Erin Dimaggio (Pennsylvania State University), who brought them to the USGS Denver Argon Geochronology Laboratory for Ar/Ar analysis. Samples were analyzed in...

This dataset includes 40Ar/39Ar data for 14 samples from the Sheep Creek carbonatite occurrence and other mineral systems in central and western Montana, USA. Samples were acquired from this area by Christopher Gammons and his students (Montana Technological University). Mineral separates of biotite and sericite from the samples were analyzed in the Denver Argon Geochronology Laboratory...

The Goat Rocks volcanic cluster is a major andesitic locus in the southern Washington Cascade Range that persisted for approximately 3 million years (3.1 Ma to 115 ka) while coeval mafic volcanoes erupted on its periphery (Wall et al., 2018; Wall, 2022). The datasets presented in this data release were collected for a study that focuses on the mantle origin of the mafic magmas and their...

Argon geochronology results date eruptions of mapped volcanic deposits north and south of the PIt River in the California Cascades. This data release includes both raw data and summary data. Summary data are the results USGS geochronologist(s) recommend be cited in geologic history publications.

Data containing field observations of potential Jemez Mountains salamander (JMS; Plethodon neomexicanus) cover objects and characteristics of underlying soils, concurrent with arthropod data collected from pitfall traps beneath selected cover objects in salamander historic habitat located in the Jemez Mountains, New Mexico from 2023-2024. We sampled potential salamander prey items...
