Fish communities in streams of the Maryland-Washington, DC-Virginia developed Piedmont, 2024 Fish communities in streams of the Maryland-Washington, DC-Virginia developed Piedmont, 2024
From May 27 to June 21, 2024, a Virginia Tech team of 5 sampled the fish community in 30 streams spanning a gradient of the developed landscape, including Potomac River, Rappahannock River, and upper Chesapeake Bay tributaries of Maryland, Washington, D.C., and Virginia, USA. These fish surveys were part of a larger stream-health study including other teams who surveyed geomorphology...

Particle size and portable X-ray fluorescence (pXRF) data from U.S. Army Base Fort Drum, Jefferson County, New York, 2024 (ver. 1.1, May 2025) Particle size and portable X-ray fluorescence (pXRF) data from U.S. Army Base Fort Drum, Jefferson County, New York, 2024 (ver. 1.1, May 2025)
The dataset documents results from particle size analysis (PSA) and portable X-ray fluorescence (pXRF) analysis conducted on a suite of sediment samples from U.S. Army Base Fort Drum, Jefferson County, New York. Samples denoted by "FD24-Sed" were collected to obtain representative samples of surficial geologic map units, and samples denoted by "FTD-WS-MW" were collected during a...
Community-sourced lower Zanclean [early Pliocene] sea surface temperature (SST) data for PRISM5.1 and PRISM5.2 time slices Community-sourced lower Zanclean [early Pliocene] sea surface temperature (SST) data for PRISM5.1 and PRISM5.2 time slices
This data set collects, from peer-reviewed and openly available research, values of sea surface temperature (SST) that occurred at select sites across the Earth during a brief period of the lower- Zanclean. SST data reported here represent, for each site, an average of SSTs, derived from alkenone analysis. The data collected are centered on two time slices. The PRISM5.1 time slice at 4...
Fracture data collected at the Route 111 bypass in Windham, New Hampshire Fracture data collected at the Route 111 bypass in Windham, New Hampshire
This data release includes fracture orientation measurements and outcrop photographs collected at new road cuts along New Hampshire Route 111 in June 2014. Road cuts along the New Hampshire State Route 111 bypass in Windham, New Hampshire expose the metasedimentary Silurian Berwick Formation intruded by multiple phases of foliated to non-foliated granite to granitic pegmatite of the...
Hydrogeomorphic Map of the Neversink Reservoir Watershed, New York Hydrogeomorphic Map of the Neversink Reservoir Watershed, New York
This Scientific Data Release is for a spatial geodatabase containing hydrogeomorphic map units within the Neversink Reservoir Watershed, New York, formatted to Geologic Map Schema (GeMS) standards. Hydrogeomorphic map units within this data release are defined as areas with distinct topographic and hydrologic characteristics, which includes both surficial geologic deposits and regions of...
Deep learning classification of landforms from lidar-derived elevation models in the glaciated portion of the northern Delaware River Basin of New Jersey, New York, and Pennsylvania Deep learning classification of landforms from lidar-derived elevation models in the glaciated portion of the northern Delaware River Basin of New Jersey, New York, and Pennsylvania
The Delaware River Basin (DRB) covers portions of five states (Delaware, Maryland, New Jersey, New York, and Pennsylvania) and several geologic provinces, encompassing much of the complex geology of the Mid-Atlantic region. This data release focuses on the recently glaciated northern DRB, which includes portions of New Jersey, New York, and Pennsylvania. Groundwater storage is...
Geochemistry of mafic and ultramafic rocks in the Eastern Blue Ridge of Virginia and North Carolina (ver. 2.0, September 2025) Geochemistry of mafic and ultramafic rocks in the Eastern Blue Ridge of Virginia and North Carolina (ver. 2.0, September 2025)
This data release includes whole rock (WR) geochemical data for 92 samples. Whole rock geochemistry data were analyzed at Actlabs in Ancaster, Ontario, Canada. Rock samples were collected from 2020 to 2024 by Naomi Becker, Arthur Merschat, Mark Carter, and Kadie Steup. The whole rock geochemistry data characterize the composition of mafic and ultramafic (MUM) rocks in the Eastern Blue...
Particle size distribution of MIS 5a aeolianites across windward islands of the Bahamas (Great Abaco, Eleuthera, San Salvador, and Long Island) (ver. 1.1, May 2025) Particle size distribution of MIS 5a aeolianites across windward islands of the Bahamas (Great Abaco, Eleuthera, San Salvador, and Long Island) (ver. 1.1, May 2025)
Recent Quaternary carbonate island sediment preservation along low-latitude coastal regions, such as in the Bahamas, contain sediment sourced from adjacent marine environments during interglacial intervals. During these interglacial intervals, denoted by odd-numbered Marine Isotope Stages (e.g., MIS 1, 3, 5), sea levels are at a highstand relative to glacial periods (e.g., MIS 2, 4, 6)...
Portable X-ray fluorescence (pXRF) data from U.S. Army Base Fort Drum, Jefferson County, New York, 2023 (ver.1.1, May 2025) Portable X-ray fluorescence (pXRF) data from U.S. Army Base Fort Drum, Jefferson County, New York, 2023 (ver.1.1, May 2025)
The dataset documents results from portable X-ray fluorescence (pXRF) analysis conducted on a suite of sediment samples from U.S. Army Base Fort Drum, Jefferson County, New York. Most of the pXRF 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...
Chesapeake Stream Team Field Sites, 2021-2024 Chesapeake Stream Team Field Sites, 2021-2024
Each year from 2021-2024, teams from the US Geological Survey and Virginia Tech studied 30 streams with a targeted gradient of land use and conservation practices across the Chesapeake Bay Watershed. The four years of the study cover the following geographic areas and land use characteristics: -Shenandoah Valley and Ridge pasture -Delmarva row crop -Pennsylvania and Maryland Piedmont...
Atlantic and Gulf Coastal Plain foraminifera: Digitized and updated taxonomy of Thomas G. Gibson’s census data Atlantic and Gulf Coastal Plain foraminifera: Digitized and updated taxonomy of Thomas G. Gibson’s census data
This foraminiferal census data was originally produced by USGS research Geologist Thomas G. Gibson in the 1960s through the early 2000s. The census data here documents evidence of foraminifer populations found in sediment samples extracted from four cores from the Atlantic Coastal Plain and the Gulf Coastal Plain. These samples represent Pliocene, Middle- Miocene and Paleocene-Eocene...
