Historical genetic resources for Northwestern Atlantic and Caribbean populations of Roseate Tern Sterna dougallii, 1879-1940 Historical genetic resources for Northwestern Atlantic and Caribbean populations of Roseate Tern Sterna dougallii, 1879-1940
Here we provide public access to UCE DNA sequences for all genetic samples in Byerly et al. 2022.
Droplet digital PCR data for the detection of Smoky Mountain Madtoms in Great Smoky Mountains National Park Droplet digital PCR data for the detection of Smoky Mountain Madtoms in Great Smoky Mountains National Park
Environmental DNA water samples were collected at multiple sites in Great Smoky Mountains National Park in 2016 and 2017 and analyzed with a droplet digital PCR assay to screen for the presence of smoky mountain madtoms. Smoky Mountain madtoms were detected within a section of Abrams Creek, known as the only stream in Great Smoky Mountains National Park that supports this species.

Groundwater-Level Elevations and Concentrations of Selected Water-Quality Properties at the Many Diversified Interests, Inc. Superfund Site, Houston, Texas, September 2022 Groundwater-Level Elevations and Concentrations of Selected Water-Quality Properties at the Many Diversified Interests, Inc. Superfund Site, Houston, Texas, September 2022
In September 2022, the U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency, collected groundwater-level elevation data and water-quality samples from monitoring wells at the Many Diversified Interests, Inc. Superfund Site in Houston, Texas to evaluate the status of groundwater contamination at this previously remediated site. The dataset includes...
MODFLOW-One-Water model used to support the Central Platte Natural Resources District Groundwater Management Plan MODFLOW-One-Water model used to support the Central Platte Natural Resources District Groundwater Management Plan
An integrated hydrologic-flow model, called the Central Platte Integrated Hydrologic Model, was constructed using the MODFLOW-One-Water Hydrologic Model code with the Newton solver. This code integrates climate, landscape, surface water, and groundwater-flow processes in a fully coupled approach. This study provided the Central Platte Natural Resources District (CPNRD) with an advanced...
Topographic and bathymetric data, structure from motion imagery, and ground control data collected at Marconi Beach, Wellfleet, Massachusetts in March 2023, U.S. Geological Survey Field Activity 2023-012-FA Topographic and bathymetric data, structure from motion imagery, and ground control data collected at Marconi Beach, Wellfleet, Massachusetts in March 2023, U.S. Geological Survey Field Activity 2023-012-FA
The data in this release re-map the beach and nearshore environment at Marconi Beach in Wellfleet, MA and provide updated environmental context for the 2021 CoastCam installation that looks out at the coast shared by beachgoers, shorebirds, seals, and sharks. This is related to the field activity 2022-014-FA and a collaboration with the National Park Service at Cape Cod National Seashore...
