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.

Relative abundance of Clostridium botulinum type E toxin gene in sediment cores collected from northern Lake Michigan near Sleeping Bear Dunes National Lakeshore, USA Relative abundance of Clostridium botulinum type E toxin gene in sediment cores collected from northern Lake Michigan near Sleeping Bear Dunes National Lakeshore, USA
This data release contains relative abundance data of the Clostridium botulinum neurotoxin type E gene (bontE) in sediment cores collected from three nearshore depositional basins near Sleeping Bear Dunes National Lakeshore (SLBE), Lake Michigan, in September 2010. Sediment cores were collected using a box corer and maximum collection depth ranged from 23 to 42 centimeters. Each sediment...
Energy Geochemistry Database Energy Geochemistry Database
The U.S. Geological Survey (USGS) has compiled the Energy Geochemistry Database (EGDB), containing 3,619,149 analytical results for 111,791 samples collected by the Energy Resources Program (ERP) to develop an understanding of the physical and geochemical processes responsible for hydrocarbon formation. It also serves as a tool to assess oil and gas potential for sedimentary basins in...
Whole Rock Major and Trace Element Chemistry for Igneous, Sedimentary, and Metamorphic Rocks from Eastern to Southwest Interior Alaska Whole Rock Major and Trace Element Chemistry for Igneous, Sedimentary, and Metamorphic Rocks from Eastern to Southwest Interior Alaska
This dataset consists of one table containing whole-rock geochemistry data for 926 rocks from eastern, central, and southwestern interior Alaska, plus analytical results for concurrently analyzed geochemical standard materials. All materials in the present study were analyzed by ALS Global between 2014 and 2025 using a range of different techniques, so multiple unique entries for a given...
Age-model codes and paleoearthquake ages for the Frazier Mountain, Pallett Creek, and Wrightwood paleoseismic sites along the Southern San Andreas Fault, California Age-model codes and paleoearthquake ages for the Frazier Mountain, Pallett Creek, and Wrightwood paleoseismic sites along the Southern San Andreas Fault, California
These datasets provide age-model codes and resultant paleoearthquake age distributions for three paleoseismic sites along the southern San Andreas Fault. The code format is compatible with the age-model program OxCal (Bronk Ramsey 2009) which calibrates radiocarbon dates to calendar years and uses stratigraphic relationships among radiocarbon samples and sedimentary units to compute
Uranium and amino acid geochronology data for marine terraces around San Luis Obispo Bay, central California, USA Uranium and amino acid geochronology data for marine terraces around San Luis Obispo Bay, central California, USA
In the San Luis Obispo Bay area of central California, interpretations of marine terrace ages have been hampered by inconsistent results from geochronological indicators (U-series ages of corals and correlations using amino acid racemization of mollusks) and seemingly contradictory paleozoogeographic aspects of fossil faunal assemblages. The two lowest-elevation terraces are Q1 (lower)...
Mean of Annual Total Surface Water Proportions from 2015 through 2024, Derived from Dynamic Surface Water Extent and Resampled to Sentinel-2 grid for the contiguous United States Mean of Annual Total Surface Water Proportions from 2015 through 2024, Derived from Dynamic Surface Water Extent and Resampled to Sentinel-2 grid for the contiguous United States
Dynamic Surface Water Extent (DSWE) annual proportions of total surface water processed to the continental US Analysis Ready Data (ARD) tile scheme (https://landsat.usgs.gov/ard_tile) in Sarbanes and Jones 2025 are here resampled to the 20 m Sentinel-2 satellite grid using bilinear interpolation with a 3 by 3 pixel moving window. The resulting 973 tiles, with values ranging from 0 to 100...
High-resolution digital surface model (DSM) and true-color image orthomosaic collected by Uncrewed Aircraft System (UAS) within the Los Planes Watershed, Baja California Sur, Mexico, 2024 High-resolution digital surface model (DSM) and true-color image orthomosaic collected by Uncrewed Aircraft System (UAS) within the Los Planes Watershed, Baja California Sur, Mexico, 2024
These data are structure from motion products from UAS providing high topographical and true-color imagery detail over a subregion within the Los Planes Watershed in La Paz, Mexico. This is part of an ongoing research partnership with the U.S. Geological Survey (Aridland Water Harvesting Study), U.S. Water Partnership (USWP), and Innovaciones Alumbra to monitor eco-hydrological feedbacks...

This data release contains the boundaries of assessment units and input data for the assessment of undiscovered oil and gas resources in the Mesaverde Group and Lance Formation in the Southwestern Wyoming Province, Wyoming, Utah, and Colorado. The assessment unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The...
Tidal Influence on Water Quality Parameters at Tributary Confluences of the Anacostia River, 2025 Tidal Influence on Water Quality Parameters at Tributary Confluences of the Anacostia River, 2025
This metadata record contains eight shapefiles with water quality parameters at the Anacostia River confluences of Hickey Run and Watts Branch, at Washington, DC, in 2025. Included in the dataset are water quality parameters (pH, turbidity, dissolved oxygen, specific conductance, and water temperature) and coordinates measured in these confluences by a remote-controlled autonomous boat...
Transient Electromagnetic Sounding Data from the Area Around the Dinero Mine Tunnel Near Leadville, Colorado Transient Electromagnetic Sounding Data from the Area Around the Dinero Mine Tunnel Near Leadville, Colorado
During August 2023, transient electromagnetic (TEM) surveys were carried out at select locations in Lake County near Leadville, Colorado upgradient from the Dinero tunnel bulkhead. TEM data were collected using an ABEM WalkTEM2 advanced instrument running acquisition software version 1.3.7.4 and using a single-turn transmitter loop (Tx) and a center-loop receiver (Rx). Tx loop dimensions...
Ground-Penetrating Radar for Depth to Bedrock in Select Watersheds near Los Planes in Southern Baja California Sur, Mexico Ground-Penetrating Radar for Depth to Bedrock in Select Watersheds near Los Planes in Southern Baja California Sur, Mexico
During December 2022 and April 2023, the U.S. Geological Survey, in cooperation with U.S. Water Partnership, collected ground-penetrating radar (GPR) data in select small subwatersheds and arroyos within the Los Planes watershed south of La Paz in southern Baja California Sur, Mexico to map the depth to bedrock for use as inputs to a groundwater flow model. This data release contains the...
