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 micrometer m

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 ridges that o

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 processed u

Geochemical data from selected pre-Middle Jurassic basement rocks beneath the Coastal Plain 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 applications rangin

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 host the Old

UAS-borne Lidar 0.5m DTM for parts of Vicksburg National Military Park - December 2022

In December 2022, the U.S. Geological Survey (USGS) flew uncrewed aerial systems (UAS) to collect very high-resolution imagery and lidar data of Vicksburg National Military Park to address areas of substantial landslide hazard within the park. The fine spatial resolution and high accuracy of this data are needed to fully characterize and quantify landslides and to understand the potential for cont

Occurrences of Pliocene Planktic foraminifers in core samples from SE Florida

Data consist of presence / absence records of planktic foraminifer species from 5 core samples at 3 localities in southeast Florida. Samples are placed in biostratigraphic zones and ages are estimated from calibrated first and last appearances of select taxa.

Cosmogenic Be-10 Exposure Data for a Boulder Field in Zepp, VA

We have dated a boulder field in Zepp, VA using cosmogenic Be-10 exposure dating. Three samples taken from boulders at three elevations in the boulder field (804 m asl, 818 m asl, and 831 m asl) were processed at the Reston Cosmogenic Nuclide (RECON) Lab and measured via accelerator mass spectrometry at the Purdue Rare Isotope Measurement (PRIME) Lab. The results of this work are summarized in the

Cosmogenic Al-26/Be-10 Isochron Burial Data for the Nussbaum Gravel at Baculite Mesa, CO

We have constrained the age of the Nussbaum Gravel at Baculite Mesa, CO using cosmogenic Al-26/Be-10 isochron burial dating. Two samples, a coarse sand and a fine gravel, were prepared for burial dating at the Reston Cosmogenic Nuclide (RECON) Lab and measured via accelerator mass spectrometry at the Purdue Rare Isotope Measurement (PRIME) Lab. The results of this work are summarized in the file “

238U/206Pb SHRIMP, 40Ar/39Ar geochronologic, and geochemical data from the Central Virginia Piedmont

The Central Virginia Seismic Zone (CVSZ) is an area of historically increased earthquake activity that is of particular importance due to its proximity to many well-populated regions in the Virginia Piedmont. Notably, the epicentral region of the 2011 magnitude (M)5.8 earthquake in Mineral, Virginia falls within the CVSZ (Horton and Williams, 2012), making this region relevant not just historicall

This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Lewisburg 30 x 60 minute quadrangle in Virginia and West Virginia. The source data used to construct this imagery consists of 1-meter resolution lidar-derived digital elevation models (DEMs). The lidar source data were compiled from different acquisitions published between 2020 and 2021. The data were processed using
