Data

The database for the Washington West 30- by 60-minute quadrangle covers an area of approximately 4,884 square kilometers (1,343 square miles) in and west of the Washington, D.C., metropolitan area. The eastern part of the area is highly urbanized, and more rural areas to the west are rapidly being developed. The area lies entirely within the Chesapeake Bay drainage basin and mostly...

This data release contains photographs and photomicrographs from drill cores and cuttings of pre-Middle Jurassic basement rocks that are buried beneath Coastal Plain sedimentary deposits in Florida. These samples provide rare insights into deeply buried rocks that have no surface exposures and no known exposed correlates. These images were acquired to support the characterization...

This data release reports the mineral abundances in samples of pre-Middle Jurassic basement rocks from twenty-nine (29) boreholes in Florida and southern Alabama. Mineral abundances are quantified from whole-rock powder X-ray diffraction (XRD) data and the Rietveld method and are reported in weight percent or, where present near the detection limit (~1 wt.% depending on mineral), as...

The Salinity and Temperature Data for South Florida Estuarine Mollusks (1994-present) database contains salinity and temperature readings from modern monitoring sites where live mollusks were observed during fieldwork performed from 1994 to present, salinity and temperature summary statistical data for each species, and location information about the sites where the monitoring data were...

The bedrock geologic map database of the Woodstock quadrangle consists of highly deformed metasedimentary rocks of the Central Maine trough, including the Silurian Rangeley and Perry Mountain Formations and the Devonian Littleton Formation. The central, northern, and eastern parts of the quadrangle are underlain by the oldest rocks in the area, the Rangeley Formation. In the southwest...

The database for the Buckner 7.5-minute quadrangle straddles three terrane boundaries in the Piedmont Physiographic Province in central Virginia: the Chopawamsic terrane, the Elk Hill Complex, and the Goochland terrane. In much of the map area, the Elk Hill Complex separates the Chopawamsic and Goochland terranes. Rocks of the Chopawamsic terrane include Ordovician metavolcanic and...

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...

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...

This dataset is derived from Synthetic Aperture Radar (SAR) data collected between July 2022-December 2024 and focuses on water inundation patterns on Jim Foot Key, located within Florida Bay. The dataset includes 13 TIFF files at 0.5 meter-3 meter horizontal resolution, that have undergone preprocessing and water thresholding methods to identify areas of inundation. These analyses were...

Manganese is a designated critical mineral, being industrially utilized for producing steel and batteries, including in the production of electric vehicles (Rozelle et al., 2021). The eastern United States hosts hundreds of manganese oxide mines that served steel production until their abandonment in the mid-twentieth century (Pegau, 1958). Many relict mines still feature accessible pits...

Thucholites are unique organic features from igneous and sedimentary rocks composed of a U-C-rich interior enclosed by an organic outer shell. Here, we evaluated thucholites from the Ediacaran Salt Range Formation of the Upper Indus Basin in Pakistan using field emission scanning electron microscopy (FESEM) and nanoscale secondary ion mass spectroscopy (NanoSIMS). The thucholites can be...

This dataset consists of Structure-from-Motion (SfM) - derived point clouds and detailed orthomosaic images of three exposures covering the Irish Valley Member of the Catskill Formation, near Selinsgrove, Pennsylvania. For each roadcut exposure, two datasets are published: an orthomosaic raster image and a point cloud. The orthomosaic raster image is a vertical outcrop orthomosaic...
