Data

Bald Eagle ridge, located about 14 km west of Leadville, Colorado, is slowly spreading and sagging, resulting in sackungen that have been monitored by the U.S. Geological Survey (USGS) since the mid-1970s (for example, Varnes and others, 1989; Varnes and others, 1990; Varnes and others, 2000). The ridge forms the southeastern flank of the glaciated Busk Creek valley and is underlain by

This dataset contains modeled distributions for 20 species under two separate emission scenarios to inform conservation opportunity areas in new Mexico. A main objective of our study was to understand how well the current portfolio of conservation areas (SWAP Conservation Opportunity Areas and Important Plant Areas) in New Mexico would serve as refugia for species at risk with a changing...

In 1976-1983, the U.S. Fish and Wildlife Service conducted systematic surveys of forest birds and plant communities on all of the main Hawaiian Islands as part of the Hawaiian Forest Bird Surveys (HFBS; Scott et al. 1986). Results of this monumental effort have guided conservation efforts and provided the basis for many plant and bird recovery plans and land acquisition decisions in...

This dataset describes the total concentration (Microplastics per Liter - MPL) of microplastics in surface water from eighteen distinct inland lakes in Minnesota. It also includes individual microplastic characteristics such as the longest measured dimension, width perpendicular to the longest dimension, color, morphology, length-to-width ratio, and composition. Spatial land use data, U...

Data release for the output of infrasound propagation modeling for the August 18th, 1992 eruption of Mount Spurr.

Observations of locations where the August 18th, 1992 eruption of Mount Spurr was heard and not heard around Alaska.

Regression models were developed with reflectance values from remote-sensing imagery and concurrent turbidity measurements during a 2 year period at Colorado River near Cameo, Colorado streamgage (U.S. Geological Survey station number 09095500). Three types of remote sensing systems were tested including satellite- and ground-based sensors. Models relate the explanatory variables...

We present the results of 14C age analysis of samples collected during multiple projects that are part of an ongoing, joint initiative of the U.S. Geological Survey Volcano Disaster Assistance Program with the Instituto Geológico Minero y Metalúrgico and Instituto Geofísico del Perú. These projects are part of a wider effort to better understand Peru’s many volcanoes and provide baseline...

This dataset was produced by the US Geological Survey (USGS) as a supporting dataset for calculating stream-gage basin characteristics within the Virginia and West Virginia StreamStats applications. This data release contains the supporting raster representations of various soil and land use attributes generated as explanatory variables for the 2025 flood-frequency study for Virginia and...

The Maumee River network contributes a significant amount of total phosphorus (P), including both sediment-bound P (sed-P) and dissolved P, to the Western Lake Erie Basin. Most Maumee River headwater streams are agricultural, with conservation management focused on limiting sediment and nutrient transport from cropland to the stream network. However, several studies have shown streambank...

This data release includes physical and chemical data for streambed-sediment samples collected at 7 locations in the Little Flatrock Creek basin in Paulding County, Ohio during July 2019. Data include total nitrogen and carbon concentrations, carbon species, total concentrations for 41 metals, and particle-size analysis; not all samples had enough for all analyses. Source samples were...

These data are comprised of beryllium-7 (7Be) and excess lead-210 (210Pbxs) activity for fine-grained, mobile, streambed sediment at seven reaches in the Little Flatrock Creek stream-channel network. This basin is monitored in cooperation with the Ohio Department of Natural Resources. During the period July 26-27, 2019 (summer low flow), the thickness and spatial extent of soft, mobile...
