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...
