Data

The data set contains location, depth, and geologic data from drill holes penetrating the Paleocene Fort Union Formation in the Williston Basin in Golden Valley County in western North Dakota.

The data set contains location, depth, and geologic data from drill holes penetrating the Paleocene Fort Union Formation in the Williston Basin in McLean County in west-central North Dakota.

The data set contains location, depth, and geologic data from drill holes penetrating the Paleocene Fort Union Formation in the Williston Basin in Mercer and Oliver Counties in central North Dakota.

Environmental DNA water samples were collected in the Greater Everglades Ecosystem between May 20-22, 2019 and analyzed to estimate Burmese python (Python bivittatus) occurrence. Twenty-eight sites were sampled in the Greater Everglades Ecosystem, with 5 field replicate samples per site, for a total of 140 water samples collected. Python eDNA was detected at 25 of the 28 sampling sites...

The data in this release characterize the beach and nearshore environment in Pea Island National Wildlife Refuge, NC at the USGS DUring Nearshore Event eXperiment (DUNEX) site and Basnight Bridge. Data include GPS surveys, reference points, and ground control points; imagery and structure-from-motion products; bathymetry data, and merged topographic and bathymetric grids. To cite a...

This dataset contains a comparison of chemical analysis results obtained by the U.S. Geological Survey (USGS) New York Water Science Center Soil and Low-Ionic Strength Water Quality Laboratory and the Adirondack Lake Survey Corporation (ALSC) Laboratory. Duplicate samples were collected biweekly from Buck Creek and the North and South Tributaries of Buck Creek from September 5, 2006...

Ratings are used for a variety of reasons in water-resources investigations. The simplest rating relates discharge to the stage of the river. From a pure hydrodynamics perspective, all rivers and streams have some form of hysteresis in the relation between stage and discharge because of unsteady flow as a flood wave passes. Simple ratings are unable to represent hysteresis in a stage...

These datasets provide early estimates of 2022 fractional cover for exotic annual grass (EAG) species and one native perennial grass species on a bi-weekly basis from May to early July. The EAG estimates are developed within one week of the latest satellite observation used for that version. Each bi-weekly release contains four fractional cover maps along with their corresponding...

These datasets provide early estimates of 2021 exotic annual grasses (EAG) fractional cover predicted on July 1 using satellite observation data available until June 28th. In previous releases, we developed and released one general EAG fractional cover map with an emphasis on cheatgrass (Bromus tectrorum) but also included number of other species, i.e., Bromus arvensis L., Bromus...

Note: this data release has been superseded by version 3.0, available here: https://doi.org/10.5066/P9AWINWZ. This Data Release contains preliminary versions of two related databases: 1) A fault sections database (“NSHM23_FSD_v2”), which depicts the geometry of faults capable of hosting independent earthquakes, and 2) An earthquake geology site information database (“NSHM23_EQGeoDB_v2”)...

The November 30, 2018, magnitude (Mw) 7.1 Anchorage, Alaska earthquake triggered substantial ground failure throughout Anchorage and surrounding areas (Grant et al., 2020; Jibson et al., 2020). The earthquake was an intraslab event with a focal depth of about 47 km and an epicenter about 16 km north of the city of Anchorage. Peak ground accelerations reached ∼30% g. Despite the...
