Data

These data describe intake of select food items by American Black Ducks during captive food trials in an effort to understand functional response.

The dataset documents results from particle size analysis (PSA) of lake sediment samples collected from Terkos Lake, Türkiye in 2024. These samples were collected as part of a multiproxy dataset to interpret paleoenvironmental changes over the late Holocene. The research was carried out as part of the USGS Ecosystems Land Change Science Program. Laboratory work was conducted using...

These datasets were compiled to support the publication Mordensky and others (2026) that evaluates the number of realizations (train-test splits) necessary to ensure robust estimates of conventional hydrothermal resource favorability when using Monte Carlo cross-validation with supervised machine learning. The datasets contained herein are the point data for the 53 publicly available...

Slope units divide terrain by drainage and divide lines to create mapping units that capture individual hillslopes. Using the software slope unit maker (SUMak) (Woodard, 2023), we delineated slope units across the contiguous United States, Hawaii, and Puerto Rico that are scaled to the fluvial-hillslope threshold (Woodard et al., 2024). Data are organized according to their respective...

In a collaborative effort between the U.S. Geological Survey (USGS) and University of South Florida (USF), seawater samples were collected along the Davis Strait aboard the research vessel (R/V) Atlantis to study ocean acidification. The Davis Strait connects the North Atlantic and the Arctic Ocean through the Canadian Arctic Archipelago (CAA) and Baffin Bay. During the cruise (USGS...

For designing buildings and other structures, the 2015 NEHRP Recommended Seismic Provisions and the 2016 ASCE/SEI 7 Standard contain maps of Risk-Targeted Maximum Considered Earthquake (MCER) spectral response accelerations and maps of Maximum Considered Earthquake Geometric Mean (MCEG) peak ground accelerations. The MCER ground motions are also in the 2017 ASCE/SEI 41 Standard and the...

For designing buildings and other structures, the 2020 NEHRP Recommended Seismic Provisions and the 2022 ASCE/SEI 7 Standard provide Risk-Targeted Maximum Considered Earthquake (MCER) spectral response accelerations and Maximum Considered Earthquake Geometric Mean (MCEG) peak ground accelerations. The MCER ground motions are also expected to be in the 2023 ASCE/SEI 41 Standard and the...

The U.S. Geological Survey, in cooperation with the Idaho Department of Water Resources, developed a water budget for a representative average (2016), dry (2021), and wet (2023) year to quantify net aquifer inputs and outputs. The water budget is published in the companion report, SIR 2026-5075 (Groundwater Budget for the Portneuf River Basin, Southeastern Idaho by H.K. Richardson). This...

This dataset includes the physical supply and use tables and the mixed-unit direct requirements matrix (A) developed for the publication: Estimating economy-wide mineral commodity consumption using hybrid input-output modeling: a case study of fluorspar, published in Ecological Economics.

This data release documents the data compiled by the U.S. Geological Survey (USGS) in cooperation with the Fort Worth District of the U.S. Army Corps of Engineers (USACE), as part of a watershed assessment that analyzed precipitation probability distributions, percent runoff, and trends in precipitation data from 1980–2019 in the Brazos, Colorado, Guadalupe, Neches, Red, and Trinity...

Controlled source audio-frequency magnetotellurics (CSAMT) data were collected throughout the Douglas Basin, within Cochise County, Arizona, to better understand the hydrogeology of the area. CSAMT data provide vertical cross-section (profile) data about the resistivity of the subsurface, which may be related to lithologic boundaries and (or) grain-size distribution in the subsurface...

We determined the sensitivity of four pleurocerid snail species, Elimia carinifera, E. melanoides, E. hydeii, and E. livescens, to three mining-related contaminants: manganese, sodium sulfate, and a mixture of calcium sulfate and magnesium sulfate in 96-hour acute exposures. We additionally determined the sensitivity of Elimia hydeii to manganese and sodium sulfate in 28-day chronic...
