Data Releases
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.

Hoary Marmot Abundance in North Cascades National Park 2007-2008 and 2016-2017 Hoary Marmot Abundance in North Cascades National Park 2007-2008 and 2016-2017
USGS and NPS biologists used distance sampling to estimate abundance of hoary marmots (Marmota caligata) in North Cascades National Park, Washington, USA during 2007-2008 and 2016-2017. Biologists resurveyed hoary marmots in 2016 and 2017 at 78 point-count stations across 19 sites surveyed by NPS in 2007-2008. Data include marmot detection distances and survey conditions used to estimate
A GIS compilation of vector shorelines and coastal bluff edge positions, and associated rate-of-change data for Barter Island, Alaska A GIS compilation of vector shorelines and coastal bluff edge positions, and associated rate-of-change data for Barter Island, Alaska
This dataset consists of rate-of-change statistics for the coastal bluffs and shorelines at Barter Island, Alaska, for the time period 1947 to 2020. Rate calculations were computed within a GIS using the Digital Shoreline Analysis System (DSAS) version 5.0, an ArcGIS extension developed by the U.S. Geological Survey. A reference baseline was used as the originating point for the...
Data on the impacts of garlic mustard from a weeding experiment in Pennsylvania 2006-2016 Data on the impacts of garlic mustard from a weeding experiment in Pennsylvania 2006-2016
Data were collected on the abundance of plants in a 10-year weeding experiment of garlic mustard, located at Trillium Trails Park in Pennsylvania. Garlic mustard was weeded annually to suppress its abundance, and the impacts of garlic mustard were measured based on the response of the plant community to garlic mustard weeding. Because garlic mustard is known to suppress mycorrhizal fungi...
Honnedaga Liming Project soil and vegetation data, 2012-2018, Adirondack region, New York, USA Honnedaga Liming Project soil and vegetation data, 2012-2018, Adirondack region, New York, USA
This dataset contains field descriptions of soil profiles and chemical analysis results of soil samples collected in the limed (T16) and reference (T24) watersheds of the Honnedaga Liming Study conducted in the watershed of Honnedaga Lake, in the southwestern portion of the Adirondack State Park in New York State, USA. Field measurements of trees, saplings and seedlings in these...

Quality-Control Data for Volatile Organic Compounds and Environmental Sulfur-Hexafluoride Data for Groundwater Samples from the Williston Basin, USA Quality-Control Data for Volatile Organic Compounds and Environmental Sulfur-Hexafluoride Data for Groundwater Samples from the Williston Basin, USA
In 2018, groundwater samples were collected from aquifers in the Williston Basin in parts of eastern Montana, western North Dakota, and northwestern South Dakota. This dataset includes quality-control data for volatile organic compounds that include data for source-solution blanks and field blanks. The dataset also includes data for sulfur hexafluoride in environmental samples of...
NRCS FY2018 Soil Properties and Interpretations, Derived Using gSSURGO Data and Tools NRCS FY2018 Soil Properties and Interpretations, Derived Using gSSURGO Data and Tools
These data depict the western United States Map Unit areas as defined by the USDA NRCS. Each Map Unit area contains information on a variety of soil properties and interpretations. The raster is to be joined to the .csv file by the field "mukey." We keep the raster and csv separate to preserve the full attribute names in the csv that would be truncated if attached to the raster. Once...
Integrated step selection analysis of turtle tracking data in the Florida Keys National Marine Sanctuary, 2008-2019 Integrated step selection analysis of turtle tracking data in the Florida Keys National Marine Sanctuary, 2008-2019
This dataset contains all input parameters required to perform integrated step selection analysis (iSSA) to quantify marine turtle habitat selection relative to marine protected areas throughout coastal Florida and the Gulf of Mexico. The iSSA is a flexible approach to compare the environmental attributes of observed steps (the linear segment connecting two consecutive observed positions...
Data for Three-dimensional distribution of groundwater residence time metrics in the glaciated United States using metamodels trained on general numerical simulation models Data for Three-dimensional distribution of groundwater residence time metrics in the glaciated United States using metamodels trained on general numerical simulation models
Residence time distribution (RTD) is a critically important characteristic of groundwater flow systems; however, it cannot be measured directly. RTD can be inferred from tracer data with analytical models (few parameters) or with numerical models (many parameters). The second approach permits more variation in system properties but is used less frequently than the first because large...
Updated Compilation of VS30 Data for the United States Updated Compilation of VS30 Data for the United States
VS30, the time-averaged shear-wave velocity (VS) to a depth of 30 meters, is a key index adopted by the earthquake engineering community to account for seismic site conditions. VS30 is typically based on geophysical measurements of VS derived from invasive and noninvasive techniques at sites of interest. Owing to cost considerations, as well as logistical and environmental concerns, VS30...
Till geochemistry from rotosonic cores in Minnesota, USA Till geochemistry from rotosonic cores in Minnesota, USA
Samples for analysis were selected from 1) archived rotosonic cores drilled by the Minnesota Geological Survey and archived at the Lands and Minerals Drill Core Library, Minnesota Department of Natural Resources, Hibbing, Minnesota, USA; or b) freshly collected rotosonic cores, collected on-site at the time of coring. Cores in the sample archive are stored in wooden core-boxes in ambient...
Bathymetric survey data of the Black River from Clearwater Lake Dam near Piedmont, Missouri, to southern Butler County, Missouri Bathymetric survey data of the Black River from Clearwater Lake Dam near Piedmont, Missouri, to southern Butler County, Missouri
The U.S. Geological Survey (USGS) in cooperation with the Little Rock District, U.S. Army Corps of Engineers conducted a bathymetric survey of the Black River from Clearwater Lake Dam near Piedmont, Missouri, to southern Butler County, Missouri, from June 16-19, 2020 and from June 22-24, 2020. One hundred and eight sites were surveyed at pre-established transect locations along a 45-mile...
