This study aimed to assess the toxicity of a commercially available pyrethrum pesticide to virile crayfish (Faxonius virilis, Hagen 1870), which were exposed for 24-h intervals during 96-h tests at two different temperatures. Adult virile crayfish were used in trials as proxy for red swamp crayfish (Procambarus clarkii, Girard 1852) to represent a conservative estimate of potency of...

Observations from 20 years of tracking Burmese pythons in southern Florida using VHF radiotelemetry. From 2005 to 2024, we implanted 305 transmitters in 142 adult Burmese pythons. There were no observations of transmitter-related mortality. Overall, 98.7% of transmitters were retained, with a 1.3% expulsion rate (n = 4 transmitters). Expelled tags were only observed in subcutaneously...

Sulfur dioxide (SO2) emission rates are a fundamental measurement for the study and monitoring of active volcanoes. Such emissions inform scientists about the level of volcanic activity or unrest, and they also present a hazard to surrounding populations. Here we present a continuation of a long-term dataset collected by the Hawaiian Volcano Observatory for over four decades using UV...

The National Water Quality Network (NWQN) for Rivers and Streams includes 105 sites monitored by the U.S. Geological Survey (USGS) National Water Quality Program (https://www.usgs.gov/mission-areas/water-resources/science/usgs-national-water-quality-network). This data release provides streamflow, nutrient, and sediment data collected and analyzed by USGS for one Mississippi River site...

Regression models were developed with reflectance values from remote-sensing imagery and concurrent turbidity measurements during a 2 year period at Colorado River near Cameo, Colorado streamgage (U.S. Geological Survey station number 09095500). Three types of remote sensing systems were tested including satellite- and ground-based sensors. Models relate the explanatory variables...

This data release contains two-dimensional hydraulic models and model results for tributaries to the Willamette River of northwestern Oregon. Model files and results are organized by river name, wherein each river with two-dimensional models is included as a child item within this data release. The model extent for each river corridor is separated into individual reaches that each extend

This dataset consists of eight sandstone samples and four ash samples collected from the Bidahochi basin that were analyzed for U-Pb zircon ages. The dataset accompanies the publication "Late Miocene Colorado River arrival in Bidahochi basin permits spillover origin of Grand Canyon". Samples were collected from the field by Ryan Crow (USGS) and John Douglass (Paradise Valley Community...

This data release presents U-Pb LA-ICP-MS ages for eight volcanic and plutonic rocks located in the Wallace and Sandpoint 1° x 2° quadrangle region of in northern Idaho and northwestern Montana. The samples were collected by Jeffery L. Mauk and Micah A. Hernandez in 2021 and were analyzed via LA-ICP-MS in 2023 in the Denver Radioisotope Lab. The weighted mean age from all concordant...

This dataset contains world production quantities for antimony, bauxite, and alumina published in the U.S. Geological Survey Minerals Yearbook, Volume I (Metals and Minerals) for the period 2010-2022. These data are presented as a table file (entity) in CSV format along with the metadata file that describes the data associated with the entity.

This data release contains climatic datasets used in U.S. Geological Survey Scientific-Investigations Report 2026-5140 that may no longer be available from the original source. The climatic datasets include near-surface air temperature and precipitation records from National Centers for Environmental Information (NCEI) U.S. Historical Climatology Network (USHCN) station Whiteriver 1 SW...

This dataset contains a point cloud, digital elevation model (DEM), orthoimagery, and uncrewed aerial vehicle (UAV) imagery covering 0.1 km2 of the Black Hollow drainage located along the upper Cache la Poudre River, in Larimer County, Colorado, USA. These products show erosional and depositional features, most notably wood jams (accumulation of large woody debris in a channel)...

In 2012, the U.S. Geological Survey’s Hawaiian Volcano Observatory (HVO) installed an array of zenith-pointing ultraviolet spectrometers to track gas emissions from summit of Kīlauea (Businger et al., 2015; Elias et al., 2018). The instruments are arranged in an arc perpendicular to the dominant trade-wind direction approximately 2 kilometers (km) southwest of the actively degassing...
