For decades, researchers have recognized the functionality of using conodont elements in biostratigraphic investigations. A growing need now exists, however, for a digital dataset of fossil data. The New England conodont dataset is the region's first publicly accessible digital collection of previously published U.S. Geological Survey (USGS) conodont paleontological data and Color...

This data release provides datasets for the conterminous United States (CONUS), characterizing rapid transitions between hydrological extremes, drought-to-flood (DtF) and flood-to-drought (FtD), over 1981–2024. The datasets include event catalogs, transition catalogs, and comparison tables used to assess prevalence, timing, rapidity, and impactfulness of hydrologic transitions and their...

A generalized hydrologic stream network (GenNet) consisting of 263,494 generalized flowlines, inclusive of coastline and terminating flow paths, was constructed for the conterminous United States (CONUS) to support efficient dynamic modeling of nutrient loads, streamflow, and downstream transport of other contaminants in streams. GenNet was generalized from the base network E3NHDPlusV2...

Ferromanganese nodules and other ferromanganese coated rocks were collected using a box core from the Samoa Basin, during 2026-604-FA. This data release includes location and depth information for each box core sample, the abundance of ferromanganese minerals in each box core sample, in units of kilograms per square meter of seafloor, and geochemical data for representative samples. The...

These data represent daily detection histories (detection/non-detection) for Myotis lucifugus at acoustic detectors deployed from 2014-2017 at various military installations in interior Alaska. Detection histories are subdivided into three seasons (early [Apr 11-June 14], mid [June 15-July 15], late [July 16-Oct 10) based on breeding biology of Myotis lucifugus. Datasets include...

Acute (96-h) and chronic (14-d) toxicity of uranium pond water, before and after zero-valent iron treatment, was evaluated using the mayfly Neocloeon triangulifer. Water chemistry data characterizing the laboratory-synthesized waters used in the experiment include specific conductance, pH, alkalinity, major-ion, and metal concentrations. Water quality data collected from the test waters...

The Great Lakes Fishery Commission sea lamprey program is concerned with the risk of lampricide applications to non-target animals, especially those of conservation concern. Conneaut Creek (Ohio and Pennsylvania) is routinely treated for larval sea lampreys (Petromyzon marinus) and contains a population of salamander mussels, which has been proposed for listing as federally endangered by...

This data release provides data on an active, multi-species planting restoration effort in the Premontane Wet Life Zone, Monteverde, Costa Rica. The study involves comparison of 13 actively restored forest stands planted three to 21 years prior on abandoned pastures to four nearby reference stands of altered primary/mature forests that were at least 70 years old (actual age unknown). All...

The US Geological Survey's Upper Midwest Environmental Sciences Center, in coordination with the US Fish and Wildlife Service's (USFWS) Branch of Migratory Bird Surveys, worked to develop, survey, and deploy an advanced aerial photography boresight in the town of Bassville Park, Florida. The intention of this boresight is to provide an extensive array of high-accuracy ground control...

Airborne electromagnetic (AEM) and magnetic survey data were collected during November 2022 over a total distance of 2,372 line kilometers over two study areas in the Pleasant Valley near the city of Coalinga, California and the region surrounding the Pyramid Hills. These data were collected adjacent to areas of oil and gas production in support of groundwater salinity mapping and...

Airborne electromagnetic (AEM) and magnetic survey data were collected during November 4–20, 2024 over a distance of 3,251 line kilometers in the western Mojave Desert, California. These data were collected in support of the U.S. Geological Survey (USGS) Earth Mapping Resources Initiative (Earth MRI), which aims to improve knowledge of the geologic framework of the United States through...

This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey of the Texas Alkaline Igneous Belt in western Texas. The airborne survey was funded by the Earth Mapping Resources Initiative. NV5 Geospatial, in collaboration with EDCON-PRJ, Inc., acquired high-precision airborne magnetic and radiometric data from January 19, 2025 to...
