Enhanced Terrain Imagery of the Front Royal 30 x 60 Minute Quadrangle from Lidar-Derived Elevation Models at 3-Meter Resolution

This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Front Royal 30 x 60 minute quadrangle in West Virginia and Virginia. The source data used to construct this imagery consists of 1-meter lidar-derived digital elevation models (DEMs) and lidar point cloud (LPC). The lidar source data were compiled from different acquisitions published between 2014 and 2021...

Zanclean Age Benthic Foraminiferal Census and Sedimentologic Data from the Yorktown Formation, Spring Grove, Va

Data consist of census counts of Pliocene benthic foraminifera from the Yorktown Formation at Pipsico Boy Scout Camp, Spring Grove, Virginia. Data consist of grain-size distribution by weight in grams of samples collected from the Yorktown Formation exposed in outcrop along the James River at Pipsico Boy Scout Camp, Spring Grove, Virginia. In total, counts of individuals from 15 samples...

Plankton biodiversity estimates from the Pliocene of North Atlantic DSDP Sites 552 and 606

Biodiversity metrics for Pliocene time series at DSDP Sites 552A and 606. Includes sample designation, depth in core, age, February, August, and mean annual sea surface temperature. Includes species richness

Alkenone temperature estimates from the Miocene and Pliocene of SE Virginia

Alkenone samples collected during September 2023 from the Farm Road, Rushmere and Pipsico localities on the James River in SE Virginia.

Spatial data of artisanal mining riverine dredges using three different Synthetic Aperture Radar detection approaches on the Madeira River, Brazil

Three semi-automated detection approaches using Sentinel-1 Synthetic Aperture Radar (SAR) have been performed to identify artisanal and small-scale mining (ASM) riverine dredges on the Madeira River in Brazil. The methods are: i) Search for Unidentified Maritime Objects (SUMO), an established method for large ocean ship detection; and two techniques specifically developed for riverine...

Particle size distribution data from U.S. Army Base Fort Drum, Jefferson County, New York, 2023

The dataset documents results from particle size analysis (PSA) conducted on a suite of sediment samples from U.S. Army Base Fort Drum, Jefferson County, New York. Most of the PSA samples were collected from representative cells in a series of five portable optically stimulated luminescence (OSL) grids, here denoted G1 through G5, to constrain variations in grain size. These samples were...

Macroinvertebrate communities in Delmarva Peninsula streams, 2022

From 2 April - 29 April 2022, a Virginia Tech team of 2-3 sampled the macroinvertebrate community in 30 Coastal Plain streams (Delaware, Maryland and Virginia, USA) as part of a larger stream-health study including other teams who surveyed geomorphology, water quality, flow, temperature,fish community, and fish health at the same 30 streams. Macroinvertebrates were sampled using a 250...

Community-sourced lower Zanclean [early Pliocene] sea surface temperature (SST) data

This data set collects, from peer-reviewed research, values of sea surface temperature (SST) that occurred at select sites across the Earth during a brief period of the lower- Zanclean.

Map data for a landslide inventory of the northwestern part of Vicksburg National Military Park, Mississippi

Vicksburg National Military Park (VICK) is in western Mississippi, situated on the loess bluffs flanking the Mississippi River. These bluffs are comprised of an accumulation of windblown silt-rich sediments, known as loess, which overlays the Oligocene Vicksburg Group. The loess deposits are thick (up to 30 meters) and easily eroded, creating deep ravines and steeply sloped elongated...

Enhanced Terrain Imagery of the Cumberland 30 x 60 Minute Quadrangle from Lidar-Derived Elevation Models at 3-Meter Resolution

This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Cumberland 30 x 60 minute quadrangle in Pennsylvania, West Virginia and Maryland. The source data used to construct this imagery consists of 1-meter lidar-derived digital elevation models (DEMs). The lidar source data were compiled from different acquisitions published between 2019 and 2023. The data were...

Geochemical data from selected pre-Middle Jurassic basement rocks beneath the Atlantic and Gulf Coastal Plains in Florida and Alabama

This data release contains whole-rock geochemical analyses from drill cores and cuttings of pre-Middle Jurassic basement rocks that are buried beneath Coastal Plain sedimentary deposits in Florida and Alabama. The analyses were acquired to support geologic mapping and characterization of little-known coastal-plain basement rock units for topical studies as in geochronology, and...

Particle size analysis results from the VA-Clarke-03 core, Cherry Hill quadrangle, Dinwiddie County, Virginia

The dataset documents results from particle size analysis conducted on a suite of sediment samples from the VA-Clarke-03 core, Cherry Hill quadrangle, Dinwiddie county, Virginia [36.931926, -77.566802]. The 44-foot-long core was collected on 05/16/2023 using the North Carolina Geological Survey Geoprobe. The core was collected from sands and gravels of the uppermost coastal plain that...
