Data and Tools

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.

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.

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.

Occupancy data for spatiotemporal distribution assessments of bull trout (Salvelinus confluentus) and rainbow trout (Oncorhynchus mykiss) in the Bruneau and Jarbidge River Basins, Idaho and Nevada, USA, in water year 2016

eDNA-based spatiotemporal distribution data (occupancy model format) for rainbow trout (Oncorhynchus mykiss) and bull trout (Salvelinus confluentus) within the Bruneau-Jarbidge Rivers Wilderness in southern Idaho and northern Nevada, USA. Data also include stream discharge and stream temperature data for each site. All data were collected between October 2015 and September 2016.

Intersects for the Buzzards Bay coastal region in Massachusetts, generated to calculate shoreline change rates using the Digital Shoreline Analysis System version 5.0

The Massachusetts Office of Coastal Zone Management launched the Shoreline Change Project in 1989 to identify erosion-prone areas of the coast. The shoreline position and change rate are used to inform management decisions regarding the erosion of coastal resources. In 2001, a shoreline from 1994 was added to calculate both long- and short-term shoreline change rates along ocean-facing...

Stable C and N isotope values in Kemp's Ridley sea turtle scutes in the northern Gulf of Mexico, 2010 to 2012

Following an explosion at the Deepwater Horizon drilling rig on April 20, 2010, MC252 an estimated 3.19 million barrels of oil leaked into the Northern Gulf of Mexico over 87 days. The endangered Kemp's ridley sea turtle (Lepidochelys kempii [Lk]) has a long established record of using the area near the well as primary foraging grounds. Resulting short- and long-term negative impacts of the...

2018 Western Lake Erie 4-Band Mosaics - 20180824_Gypsum

High-resolution digital aerial imagery was collected on August 23 and 24, 2018, with an 80-megapixel Phase One iXU-R 180 natural color aerial camera co-mounted with a Phase One iXU-RS 160 achromatic aerial camera. Software co-registers the simultaneously collected images to create 4-band imagery that can be displayed in either true color (RGB) or color-infrared (CIR) format. The camera system...

Alpine Vegetation Trends in Glacier National Park, Montana 2003-2018

This dataset is focused on alpine plant species presence/absence, species turnover, and trends in species abundance on four mountain summits in Glacier National Park, Montana, USA from 2003 through 2014. Two summit sites were established in 2003 on Dancing Lady and Bison Mountain, east of the continental divide. Two additional summit sites were established in 2004 on Pitamakin and Mt. Seward,...
