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.

Chemical and physical data for sediment source tracking of streambed sediment in Black Creek, Indiana, tributary to the Maumee River and western Lake Erie, July 2019 Chemical and physical data for sediment source tracking of streambed sediment in Black Creek, Indiana, tributary to the Maumee River and western Lake Erie, July 2019
Data include total nitrogen and carbon, carbon species, total metal, and particle-size analyses of soft streambed from the Black Creek basin, Allen County, Indiana that was collected in July 2019. These data will be used in a sediment-source mixing model in order to attribute the proportional contribution of individual sources to suspended sediment in the basin. Source samples were...
U.S. Geological Survey Mineral Commodity Summaries 2024 Data Release (ver. 2.0, March 2024) U.S. Geological Survey Mineral Commodity Summaries 2024 Data Release (ver. 2.0, March 2024)
This database contains the United States salient statistics and world production statistics for over 88 nonfuel mineral commodities. Salient statistics for the United States includes items such as production, imports, exports, price, stocks, apparent consumption, and/or net import reliance for nonfuel mineral commodities. The database contains separate table files (entities) in CSV...
Geospatial characterization of salt marshes in Maine Geospatial characterization of salt marshes in Maine
This data release contains coastal wetland synthesis products for the state of Maine. Metrics for resiliency, including the unvegetated to vegetated ratio (UVVR), marsh elevation, tidal range, and lifespan, are calculated for smaller units delineated from a digital elevation model, providing the spatial variability of physical factors that influence wetland health. The U.S. Geological...
Enhanced Terrain Imagery of the Pittsburgh East 30 x 60 Minute Quadrangle from Lidar-Derived Elevation Models at 3-Meter Resolution Enhanced Terrain Imagery of the Pittsburgh East 30 x 60 Minute Quadrangle from Lidar-Derived Elevation Models at 3-Meter Resolution
This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Pittsburgh East 30 x 60 minute quadrangle in Pennsylvania. The source data used to construct this imagery consists of 1-meter resolution Lidar-derived digital elevation models (DEMs). The lidar source data were compiled from different acquisitions published between 2020 and 2021 and downloaded from the USGS...
Predictions for the presence of submersed aquatic vegetation in the upper Mississippi River, USA, from years 2010-2019 Predictions for the presence of submersed aquatic vegetation in the upper Mississippi River, USA, from years 2010-2019
The datasets are to accompany a manuscript describing the prediction of submersed aquatic vegetation presence and its potential vulnerability and recovery potential. The data and accompanying analysis scripts allow users to run the final random forests predictive model and reproduce the figures reported in the manuscript. Files from several data sources (aqa_2010_lvl3_pct_oute_joined_VEG...
Digital elevation model of the lava dome in the crater of Mount St. Helens on October 20, 1988 Digital elevation model of the lava dome in the crater of Mount St. Helens on October 20, 1988
The catastrophic, explosive eruption of Mount St. Helens, Washington, on May 18, 1980, is the most well-known eruption of the volcano. Less well known is the May 18th eruption marked the beginning of a period of eruptive activity that lasted through 1986. From October 1980 through October 1986, a series of 17 dome-building episodes added millions of cubic meters of lava to the crater...
