As part of an effort by the U.S. Geological Survey (USGS) to better understand topographic and structural conditions that promote slow spreading and sagging of mountain ridges (Varnes and others, 1989), USGS researchers began surveying monitoring points at Bald Eagle ridge in the Sawatch Range of Colorado in 1975 (Radbruch-Hall and others, 1976; Varnes and others, 1990). Bald Eagle ridge...

The U.S. Geological Survey (USGS) Woods Hole Coastal and Marine Science Center deployed a four-legged bottom landing frame (nanopod) containing oceanographic instruments to collect measurements of winter wave conditions directly offshore of Marconi Beach in Wellfleet, MA. Supplementary sediment samples were collected to characterize grain size. Marconi Beach is the site of ongoing...

NOAA’s Assessment Technical Support Unit (TSU) created a suite of temperature and precipitation metrics of extremes and threshold exceedance variables based on the Climate Model Intercomparison Program Phase 6 CMIP6 Localized Constructed Analogs (CMIP6-LOCA2) data set to support the Fifth National Climate Assessment (NCA5). Following the v20240915 revision of the CMIP6-LOCA2...

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...

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...

A Smart Dynamic Cone Penetrometer (DCP) system allows for the partially automated collection of cone penetrometer data (CPT) to determine mechanical properties of soil along a vertical profile. A smart DCP system was used to collect soil penetration-with-depth values at 19 sites across the mountainous regions of Puerto Rico. The 19 sites were co-located at the United States Geological...
