Data

This data release compiles the inputs and outputs for a nitrogen mass balance model for nine small agricultural watersheds within the Chesapeake Bay nontidal watershed. Data inputs include annual nonpoint source nitrogen input, plant uptake, and output, and total discharge from 1985-2020 for each of the agricultural watersheds. Data inputs also include median groundwater age used to...

Mauna Loa volcano, Island of Hawaiʻi, erupted from November 27 to December 10, 2022, sending lava flows across the summit caldera (Mokuʻāweoweo) and into the upper Southwest Rift Zone, before focusing in the Northeast Rift Zone at fissure 3, sending a lava flow down the north flank that threatened a major highway. During the eruption, there was a need for updated terrain data to update...

Mauna Loa volcano, Island of Hawaiʻi, erupted from November 27 to December 10, 2022, sending lava flows across the summit caldera (Mokuʻāweoweo) and into the upper Southwest Rift Zone, before focusing in the Northeast Rift Zone at fissure 3, sending a lava flow down the north flank that threatened a major highway (Zoeller and others, 2024). During the eruption, U.S. Geological Survey...

Ferromanganese nodules and other ferromanganese coated rocks were collected using a box core from the Samoa Basin, during 2026-604-FA. This data release includes location and depth information for each box core sample, the abundance of ferromanganese minerals in each box core sample, in units of kilograms per square meter of seafloor, and geochemical data for representative samples. The...

This data release contains biological information collected in the field during a 78-day in situ mussel exposure. We collected length and survival data from Fatmucket that were held in mussel silos from five potential mussel augmentation sites in the Clinton River watershed, near Detroit, Michigan. Additionally, this data release contains data from a 28-day laboratory sediment bioassay...

The orthoimagery, digital surface model and point cloud presented here document conditions at Pickle Pond in Superior, Wisconsin in August 2020, prior to planned ecological restoration. Aerial images were collected using a DJI Phantom with FC6310 sensor at a nominal elevation of approximately 70 meters above the surface of the lake water. Data were processed using structure-from-motion...

This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over the Laramie Mountains region of Wyoming. The airborne survey was funded by the Earth Mapping Resources Initiative (Earth MRI). The survey was designed by the USGS in collaboration with the Wyoming State Geological Survey and contracted by the USGS. The survey was...

The two datasets consist of capture-mark-recapture (cmr) data for brown treesnakes (Bioga irregularis), and a database containing information about supplemental food added to the population in 2009. The cmr data were collected in the closed population (CP) on Andersen Air Force Base in Guam. These data were used to assess how the population growth rate was affected by two perturbations...

These data represent daily detection histories (detection/non-detection) for Myotis lucifugus at acoustic detectors deployed from 2014-2017 at various military installations in interior Alaska. Detection histories are subdivided into three seasons (early [Apr 11-June 14], mid [June 15-July 15], late [July 16-Oct 10) based on breeding biology of Myotis lucifugus. Datasets include...

The AltEn bioenergy plant (Mead, Nebraska, USA) previously (2015 to 2021) generated ethanol from almost 100% unused/expired treated corn seeds. This use of treated corn seeds as a feedstock for ethanol production resulted in accumulation of large amounts of contaminated wastewater and solid residue at the plant, a portion of which was applied to surrounding farmland. To evaluate the...

Airborne electromagnetic (AEM) and magnetic survey data were collected during November 4–20, 2024 over a distance of 3,251 line kilometers in the western Mojave Desert, California. These data were collected in support of the U.S. Geological Survey (USGS) Earth Mapping Resources Initiative (Earth MRI), which aims to improve knowledge of the geologic framework of the United States through...

The West Salt Creek rock avalanche (refer to Figure 1 for location, .pdf and .jpg files are provided) occurred on May 25, 2014, and filled the West Salt Creek valley with a hummocky deposit that ranged up to ~38 m thick (White and others, 2015; Coe and others, 2016). The central core of this deposit continued to move for at least one hour after other parts of the deposit had stopped...
