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.

Carbon dioxide flux, vegetation, and soils data from artificial ponds in North Dakota, USA, 2021 Carbon dioxide flux, vegetation, and soils data from artificial ponds in North Dakota, USA, 2021
This data release presents data that were collected as part of a larger effort to assess the carbon balance of recently exposed (i.e., no vegetation cover) wetland sediments. This work was part of an international collaborative effort associated with the Dryflux II project. During June and July 2021, data were collected from three artificial ponds located near Jamestown, North Dakota, to...
Coking coal of the United States: Modern and historical locations of coking coal mining locations and chemical, rheological, petrographic, and other data from modern samples Coking coal of the United States: Modern and historical locations of coking coal mining locations and chemical, rheological, petrographic, and other data from modern samples
For the open-file report we collected new coking coal samples from Alabama, Kentucky, Oklahoma and Arkansas and analyzed them for proximate and ultimate analyses; calorific value; sulfur forms; major-, minor-, and trace-element abundances; free swelling indices; Gieseler plasticity; ASTM dilatation; coal petrography, and several other tests [air-dry loss (ADL), residual moisture (RM)...
Combined wildland fire datasets for the United States and certain territories, 1800s-Present Combined wildland fire datasets for the United States and certain territories, 1800s-Present
First, we would like to thank the wildland fire advisory group. Their wisdom and guidance helped us build the dataset as it currently exists. This dataset is comprised of two different zip files. Zip File 1: The data within this zip file are composed of two wildland fire datasets. (1) A merged dataset consisting of 40 different wildfire and prescribed fire layers. The original 40 layers...
Basin characteristic rasters used in the update of Hawaiʻi StreamStats, 2022 Basin characteristic rasters used in the update of Hawaiʻi StreamStats, 2022
In cooperation with the State of Hawaii Department of Transportation, the U.S. Geological Survey (USGS) has computed a series of basin characteristic rasters for Hawaii to be implemented into the USGS StreamStats application (https://streamstats.usgs.gov/ss/). The basin characteristics, along with geospatial datasets for watershed delineation published as a separate USGS data release...
Geospatial datasets for watershed delineation used in the update of Hawaiʻi StreamStats, 2022 Geospatial datasets for watershed delineation used in the update of Hawaiʻi StreamStats, 2022
The U.S. Geological Survey (USGS), in cooperation with the State of Hawaii Department of Transportation, has compiled and processed a series of geospatial datasets for Hawaii to be implemented into the USGS StreamStats application (https://streamstats.usgs.gov/ss/). These geospatial datasets, along with basin characteristic datasets published as a separate USGS data release (https://doi...
Stream temperature observations during summer 2021 for sites in the Sleepy Creek watershed, West Virginia Stream temperature observations during summer 2021 for sites in the Sleepy Creek watershed, West Virginia
This Data Release contains stream temperature observations for 10 sites in the Sleepy Creek Watershed (West Virginia) during summer 2021. Data were collected using Onset ProV2 temperature gages within perforated PVC cases attached to stream substrates with rebar. Temperature gages were deployed and retrieved by volunteers with the Sleepy Creek Watershed Association. Temperature records...
