Data

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...

Sagebrush songbird fledglings (Brewer's sparrow, sagebrush sparrow, and sage thrasher) were measured and tracked using radio telemetry in Pinedale, Wyoming during 2021-2023.

This data release presents model inputs and outputs to support an investigation of occurrence and temporal changes of imidacloprid from the U.S. Geological Survey National Water Quality Network spanning 77 sites between 2013 and 2022. Imidacloprid is a neonicotinoid insecticide used to control a wide range of agricultural and non-agricultural insect pests. The Seasonal Wave and...

In 2005, a silvicultural restoration study was implemented to observe the response of individual red spruce to various percent basal area (BA; m2) removal treatments of competing hardwood species. These treatments consisted of four different basal area removals: control was 0 percent, low was about 33 percent, medium was about 67 percent, and high was about 100 percent around individual...

This dataset contains water quality data collected in the Mississippi Sound before (pre) and after (post) barrier island restoration of Cat and Ship Island, Mississippi. The barrier island restoration included sand placement which has the potential to alter water quality conditions within the Mississippi Sound estuary. Therefore, water quality monitoring was conducted at five...

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...

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)...

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...

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...

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...

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...
