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.

Paired Watershed and Characteristic Trait Data for the Los Planes Basin Research Ranch Watersheds: U.S. Geological Survey Data Release Paired Watershed and Characteristic Trait Data for the Los Planes Basin Research Ranch Watersheds: U.S. Geological Survey Data Release
Watershed pairing is an approach used to assess effects of restoration on a landscape by comparing conditions across a treatment watershed and a control watershed, and then quantifying the differences. When the watersheds are statistically paired, the control watershed can serve as a baseline of conditions compared to the treatment watershed. We apply a watershed pairing analysis across...
High-resolution orthoimagery and digital surface models of Fern Ridge Lake, Oregon, during annual low pool, January and February, 2023 High-resolution orthoimagery and digital surface models of Fern Ridge Lake, Oregon, during annual low pool, January and February, 2023
In cooperation with the U.S. Army Corps of Engineers (USACE), the U.S. Geological Survey (USGS) deployed ground control points and coordinated aerial photograph acquisition of Fern Ridge Lake, a multi-purpose reservoir in western Oregon impounded by the 13-m tall Fern Ridge Dam. Aerial photographs were acquired by the Civil Air Patrol (CAP) during winter 2023 when water levels were at or...
Data release for New evidence for eolian activity and mammoths on Santa Rosa Island prior to the Last Glacial Maximum Data release for New evidence for eolian activity and mammoths on Santa Rosa Island prior to the Last Glacial Maximum
Sea-level fluctuations due to the growth and decay of continental ice sheets of the Quaternary exert a strong influence on geologic processes along coastlines. The California Channel Islands are no exception to this, and many studies have been conducted that focus on the extremes of these glacial-interglacial cycles, such as the last glacial period (marine isotope stage [MIS] 2) and the...
A database of artisanal, small-scale, and large-scale mining in the Copperbelt region of the Democratic Republic of Congo and Zambia A database of artisanal, small-scale, and large-scale mining in the Copperbelt region of the Democratic Republic of Congo and Zambia
Cobalt, designated a critical mineral by the European Union and the United States, is a crucial component of the lithium-ion batteries found in cell phones, electric vehicles, and personal computing devices. Over half of the world’s cobalt supply is produced in the Democratic Republic of the Congo (DRC), where cobalt is mined in both large-scale and artisanal or small-scale operations...
Microtremor array data on Whidbey Island, Washington Microtremor array data on Whidbey Island, Washington
The U.S. Geological Survey collected a grid of microtremor data points using Smartsolo 3-component seismic sensors from August 7th to August 11th, 2023. These sensors have a five Hz resonance frequency. The grid was deployed over a section of the Utsalady Point fault that runs east-west across the southern portion of the Naval Air Station Whidbey Island, Washington State. For four days...
Digital Surface Models of the Kajaki Dam in the Helmand Valley, Afghansitan from 1952 Historical Aerial Photos. Digital Surface Models of the Kajaki Dam in the Helmand Valley, Afghansitan from 1952 Historical Aerial Photos.
This study applied historical aerial imagery and satellite imagery to create digital surface models (DSMs) of the Helmand River Valley situated in southwestern Afghanistan. The historical imagery, collected in 1952 by Fairchild Aerial Surveys Incorporated (FAS), at 1:40,000 scale, represents the earliest known aerial photographic archive of the Helmand Valley landscape. Structure-from...
