Science Datasets

The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Reanalysis of Selected Archived NURE-HSSR Sediment and Soil Samples from Arizona, California, Idaho, Montana, Nevada, New Mexico, and Utah

Beginning in November of 2015, a project was undertaken to reanalyze approximately 60,000 archived sample splits collected as part of the National Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) project from selected areas in Arizona, California, Idaho, Montana, Nevada, New Mexico, and Utah. A small amount (approximately 0.25 g) of sieved -75...

Cold-water coral microbiomes (Paramuricea placomus) from Baltimore Canyon: raw and processed data

The files in this data release are the raw and processed DNA sequence files referenced in the submitted journal article by Kellogg et. al. titled "Bacterial Community Diversity of the Deep-Sea Octocoral Paramuricea placomus." They represent a 16S rRNA gene amplicon survey of the coral's microbiome completed using Roche 454 pyrosequencing with titanium reagents.

Cold-water coral microbiomes (Anthothela spp.) from Baltimore and Norfolk Canyons: raw and processed data

The files in this data release are the raw and processed DNA sequence files referenced in the submitted journal article by Lawler et. al. titled coral-associated bacterial diversity is conserved at the host-genus level in deep-sea Anthothela spp." They represent a 16S rRNA gene amplicon survey of the coral's microbiome completed using Roche 454 pyrosequencing with titanium reagents.

Sea Floor Sediment Samples, Seabed Imagery, and CTD Water Column Data Collected on Stellwagen Bank in January 2017, U.S. Geological Survey Field Activity 2017-009-FA

This field activity is part of the effort to map geologic substrates of the Stellwagen Bank National Marine Sanctuary region off Boston, MA. The overall goal is to develop high-resolution (1:25,000) interpretive maps, based on multibeam sonar data and seabed sampling, showing surficial geology and seabed sediment dynamics.

Minimal offshore extent of ice-bearing (subsea) permafrost on the U.S. Beaufort Sea margin

Using a compilation of more than 50,000 stacking velocities from ~100,000 line-km of industry-collected multichannel seismic reflection data acquired over 57,000 square kilometers of the U.S. Beaufort Sea continental shelf, we derive the average (bulk) velocity in the upper 750 milliseconds of two-way travel time (TWTT).

Aerial imagery from unmanned aerial systems (UAS) flights and ground control points: Plum Island Estuary and Parker River NWR (PIEPR), February 27th, 2018

These images were collected as part of an effort to document marsh stability over time and quantify sediment movement using UAS technology. Each UAS was equipped with either a Ricoh GRII digital camera for natural color photos, used to produce digital elevation models and ortho images, or a MicaSense RedEdge multi-spectral camera that captures five specific bands of the visible spectrum.

Rare Earth Element Occurrences in the United States

Version 4.0 of this data release provides descriptions of more than 200 mineral districts, mines, and mineral occurrences (deposits, prospects, and showings) within the United States that are reported to contain substantial enrichments of the rare earth elements (REEs). These mineral occurrences include mined deposits, exploration prospects, and other occurrences with notable concentrations of...

2019 Known and Probable Grizzly Bear Mortalities in the Greater Yellowstone Ecosystem

Identifying the locations and causes of grizzly bear mortality is another key component in understanding the dynamics of this population. Over 80% of all documented bear mortalities are human-caused. Tracking human-caused bear deaths helps define patterns and trends that can direct management programs designed to reduce bear mortality.

Change in fire probability from baseline to 2040-2069 using CGCM-projected climate values

Globally, changing fire regimes due to climate is one of the greatest threats to ecosystems and society. This dataset presents projections of historic and future fire probability for the southcentral U.S. using downscaled climate projections and the Physical Chemistry Fire Frequency Model (PC2FM, Guyette et al., 2012). Climate data from 1900-1929 and projected climate data for 2040-2069 and...
