Embryonic zebrafish (Danio rerio) were exposed to 0, 1, 5, 10, or 50 micrograms per liter carbamazepine (CBZ) from 2 hours post fertilization (hpf) through hatching, and then sampled at 48, 72, or 144 hpf. Larvae collected at 48, 72, and 144 hpf were assessed for transcriptomic profiles using RNA sequencing. Larvae collected at 72 and 144 hpf time points were assessed for histological...

Pollutants present in stormwater runoff can severely degrade water quality in aquatic habitats. The tire-derived chemical 6PPD-quinone is one such pollutant present in stormwater that is known to significantly impact the survival of salmonids. 6PPD-quinone is derived from 6PPD, the primary antiozonant used to protect tire rubber from ozone attack and degradation. Alternative antiozonants...

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...

Silver maple (Acer saccharinum L.) is a fast-growing, flood-tolerant species common in bottomland forests of eastern North America. Tree-ring research on silver maple is limited due to the species’ relatively short lifespan and reputation for indistinct rings. The wood anatomy of silver maple is characterized by a diffuse-porous ring structure with small, uniformly distributed vessels...

This dataset contains an updated version of the catalog of tremor in south-central Alaska described in: Wech, A.G., 2016, Extending Alaska’s plate boundary—Tectonic tremor generated by Yakutat subduction: Geology, v. 44, no. 7, p. 587–590. [Also available at https://doi.org/10.1130/G37817.1.] The original catalog spans from 2007 to 2015, and the update extends tremor detection coverage...

As part of the Clean Water Act, Section 319 authorizes funding that is distributed to Mississippi Department of Environmental Protection Agency to address nonpoint sources of pollution in the state of Mississippi. For this project, Weighted Regressions on Time, Discharge, and Season (WRTDS) models (Hirsch and others, 2010) were used to perform a trend analysis on nitrogen and phosphorus

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...
