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.

Shallow Coal Exploration Drill-Hole Data for Arkansas Shallow Coal Exploration Drill-Hole Data for Arkansas
Shallow (300 ft or less) coal exploration drill-hole data from 692 wells located in Arkansas are provided in this data release. The well locations extend over nine Arkansas counties and were drilled between 1975 and 1977, primarily by Phillips Petroleum Company (Phillips). Also included in the dataset are 79 wells drilled by Tenneco. The data were donated to the U.S. Geological Survey...
Everglades mangrove vegetation data from 23 long-term plots (1992-2011) Everglades mangrove vegetation data from 23 long-term plots (1992-2011)
Twenty-three long-term mangrove vegetation plots were established between 1992-1997 within the southwest coastal region of Everglades National Park (Florida, USA) to quantify tree damage and recovery following hurricanes and to understand the effects of global climate change. Many of the mangrove vegetation plots were associated with hydrology, soil porewater, and soil surface elevation...
Microscopic Images of Leonardite and Humate Biochar: Using Reflected Light Microscopy in Biochar Characterization Microscopic Images of Leonardite and Humate Biochar: Using Reflected Light Microscopy in Biochar Characterization
Biochar is a carbon-rich substance that is derived through the thermochemical conversion of biomass. Biochar is recognized for its significance in environmental applications and sustainable agriculture. In an effort to comprehend how the source material and pyrolysis parameters influence its properties, reflected light microscopy is being used to produce microscopic images for analysis...
Digitized mangrove-marsh ecotone boundaries for Everglades National Park and Big Cypress National Preserve (Florida, USA) in 2013 and 2019 Digitized mangrove-marsh ecotone boundaries for Everglades National Park and Big Cypress National Preserve (Florida, USA) in 2013 and 2019
This dataset consists of a file geodatabase containing the digitized ecotone boundaries between mangroves and freshwater marsh in 2013 and 2019 at 14 systematically selected segments in Big Cypress National Preserve and Everglades National Park (southwest Florida, USA).
US non-native plant occurrence and abundance data and distribution maps for Eastern US species with current and future climate US non-native plant occurrence and abundance data and distribution maps for Eastern US species with current and future climate
This is a dataset containing aggregated non-native plant occurrence and abundance data for the contiguous United States. We used these data to develop habitat suitability models for species found in the Eastern United States using locations with 5% cover or greater. We adapted the INHABIT modeling workflow (Young et al. 2020), using a consistent set of climatic predictors that were...
Suspended Sediment Data and Loads in the Fountain Creek Watershed, Colorado (ver 2.0, June 2025) Suspended Sediment Data and Loads in the Fountain Creek Watershed, Colorado (ver 2.0, June 2025)
This data release consists of daily mean streamflow, daily mean suspended sediment concentration (SSC), and daily mean suspended sediment load (SSL) data for selected U.S. Geological Survey (USGS) streamgage sites within the Fountain Creek watershed, separated by water year. Each file also includes USGS approval levels and any associated qualifiers that were applied to the values. The...
