Data

Rock physical property measurements were collected on core samples to help understand the causative sources of gravity and magnetic survey anomalies in northwestern Minnesota. A total of 410 measurements of magnetic susceptibility and density on Archean core samples from 20 boreholes have been conducted. The measurements aid in interpretation of gravity and airborne magnetic data that...

Tephra samples from the Kulanaokuaiki Tephra Member (400 to 1000 C.E.) of the Uwēkahuna Ash (200 B.C.E. to 1000 C.E.) were sampled from Kīlauea volcano, Island of Hawai‘i. Samples were analyzed by dynamic imaging analysis using Microtrac CAMSIZER P4 and X2 instruments for grain shape and Anton nitrogen pycnometer instruments for density in the U.S. Geological Survey - Hawaiian Volcano...

Recent work in the Great Basin region of the western United States has made it possible to predict the depth of hydrothermal reservoirs (i.e., the depth at which heat is accumulated prior to ascent via hydrothermal upflow) identified through geochemistry and to contextualize the spatial patterns of these reservoir depths. Chemical geothermometers use the chemical and mineral constituents...

This data release provides access to a low-altitude, aeromagnetic survey of a part of northwestern California. These data were acquired to support earthquake and tsunami hazard investigations and geologic mapping of the greater Trinidad area of northwestern California. Magnetic data are provided as a database and the residual magnetic intensity is provided as a grid.

In this work, we refined and expanded the coseismic surface rupture map of the 1983 M6.9 Borah Peak earthquake coseismic rupture mapping at a scale of 1:500. While earlier work (DuRoss et al., 2019; Bello et al., 2020, 2021) used structure-from-motion (SfM) methods to construct digital elevation models (DEMs) derived from small uncrewed aerial systems (sUAS or drone) imagery, the...

Concentrations of 6PPD-quinone, a primary transformation product of the rubber tire additive 6PPD, were measured in small mouth bass that were not exposed to 6PPD-quinone and used as quality control fish matrix for method optimization and in whole-body coho salmon fry that were exposed to known water concentrations of 6PPD-quinone during 96-hour acute toxicity exposures. Two different...

This data set includes acoustic telemetry detection data and biological attributes for walleye and grass carp in the Sandusky River and Bay, OH. The detection data also includes information about the receivers that recorded the detection of acoustic telemetry tags implanted in walleye and grass carp from from 2014 to 2021. Receiver attributes include location and deployment history of...

The data being released were part of a project funded by the Section 40804 Ecosystem Restoration of the Bipartisan Infrastructure Law (PL-117-58) in support of advancing a national revegetation effort. Data included are from a series of DNA degradation experiments targeting the mitochondrial 16S rRNA gene of the European honeybee (Apis mellifera). This study sought to determine how...

Data describe the detection of Spectaclecase (Cumberlandia monodonta) female and male mitotype environmental DNA (eDNA) during a spawning event. Water samples (approximately 1L) were collected from an outdoor raceway tank containing C. monodonta from March to April 2021 and analyzed for the presence of sex-specific eDNA. Parameters described in this data release include water quality...

This dataset contains environmental DNA (eDNA) data for two separate tests of a novel quantitative polymerase chain reaction (qPCR) assay for detection of Dakota skipper (Hesperia dacotae) from inflorescences. One test was conducted in a controlled setting, and the other was conducted in a field setting. Also included are qPCR data for negative controls and standard dilutions of Dakota...

This dataset includes eDNA concentrations of water samples from an experimental release of lake trout (Salvelinus namaycush) slurry used to analyze eDNA transport in the Big Piney River, Missouri. The spectaclecase (Cumberlandia monodonta) was also included as a target species due to the proximity of a known spectaclecase population at the slurry release site. The slurry, a frozen block...

Data describe a mesocosm study for the detection of Mucket (Ortmanniana ligamentina) female and male mitotype environmental DNA (eDNA) during a spawning event. Water samples (approximately 1L) were collected every Monday and Thursday for 4 weeks during August 2021 from a pond located at Columbia Environmental Research Center containing O. ligamentina and analyzed for the presence of sex...
