This U.S. Geological Survey (USGS) data release provides the data used to predict areas with the greatest probability of ephemeral stream channel instability on north side of the Grand Valley in western Colorado, during 2018-20. The USGS developed a method for automatically extracting channel cross-section geometry from existing remotely sensed terrain models. Based on estimated flood stage and surrogate streamflows, hydraulic characteristics were calculated. The channel geometries and hydraulic characteristics were used to estimate channel stability using a statistical model. Cross-section stabilities were determined from a stream channel stability assessment for a subset of 1,406 visited (field observed) locations...
This dataset contains Sr:Ca of water and fin ray samples of native fish to evaluate upstream fish passage through a navigation lock in the Des Plaines River (Brandon Roads Lock and Dam). Fin ray samples from several native fish taxa (catostomids, ictalurids, centrarchids, and lepisosteids) were collected in two river reaches downstream of Brandon Roads Lock and Dam, and in a river reach upstream of Brandon Roads Lock and Dam. Fin ray Sr:Ca derived from microchemistry analyses of fin ray materials from a laser ablation transect is included as both edge values and entire transect (including edge). Edge values of Sr:Ca were used to characterize chemical signatures of residency for each of the rivers and make comparisons...

Data includes fish abundance and habitat data collected at ten sites in the Sandusky River, OH. Fish were collected using two 3.67 m long hoop nets with an initial hoop diameter of 0.91 m. Nets were set perpendicular to the current, opening toward the shoreline. Nets were set for approximately 24 hours and catch rates for each set were defined as the number of fish caught in the two hoop nets per 24-hour sampling period. Fish were identified to species, measured for total length (mm), and released. Water quality was taken daily at each site at approximately the same time of day with a YSI Exo2 multiparameter sonde. Physical habitat data was recorded at the start of each trial. Vegetation coverage was characterized...

In 2016, for the first time, an abundance of age-0 silver carp (Hypophthalmichthys molitrix) were captured at several sites upstream of Lock and Dam 19 on the Upper Mississippi River near Keokuk, Iowa. These data were collected in an attempt to determine the early life environments and frequency and timing of the reproductive events that led to a large year class of age-0 silver carp. This information is important for informing decisions about control measures. We sampled these fish to determine age (days) and early life environments using their otoliths. Sampled age-0 silver carp were collected from navigation Pools 18 and 19 from July–October 2016 using a variety of sampling gears. We aged these fish by counting...

Wind speed, wind direction (3D) and gas concentrations are measured at 10 Hz and statistically processed using the eddy covariance technique to half-hour estimates of flux rates of gas exchange between the ecosystem and atmosphere. Three gases were measured: carbon dioxide, methane and water vapor. Simultaneous measurements of environmental drivers are also measured and recorded as half-hourly values: photosynthetic photon flux density, downwelling and upwelling short and long wave radiation, air temperature, relative humidity and precipitation. Variable names and units follow AmeriFlux and FLUXNET standards. This site is a flotant herbaceous freshwater marsh in Salvador Wildlife Management Area near Luling, LA.
This data release provides quantitative whole rock geochemical results from The Geysers vapor-dominated geothermal field in California.

This data release provides semiquantitative mineralogy results from X-ray diffraction (XRD) analyses of mineral scales from The Geysers vapor-dominated geothermal field in California. The mineral species and their abundances are reported in weight percent and values have been normalized to total 100 percent for each sample. The X-ray diffraction results show that the mineral samples from the wellheads are primarily composed of ammonium (NH4+) sulfate minerals and sassolite B(OH)3, whereas sulfide minerals such as cinnabar and pyrite are the most abundant minerals observed in the power plants. Mineral scales vary along the steam flow path, from the wellhead to power plants. Relatively abundant iron oxide and iron...

The dimensions of each organism were measured with a Whipple grid and the biovolume was estimated using the simplest geometric shape (e.g., cylinder, cone, sphere, etc.) that best fit the shape of each taxon. Shapes were assigned according to Hillebrand et al. (1999). Biovolume was calculated for the first five organisms/counting units of each taxon identified in a sample. The average biovolume was then used to calculate total biovolume of each taxon in the sample.

The risk of lampricide applications (such as 4-Nitro-3-(trifluoromethyl)phenol, TFM) to non-target fauna continues to be a concern within the Great Lakes Fishery Commission sea lamprey control program, especially among imperiled aquatic species—such as native freshwater mussels. The Grand River (Ohio) is routinely treated for larval sea lampreys (Petromyzon marinus) and this river contains populations of the Round Hickorynut mussel (Obovaria subrotunda) which was Federally listed in 2023. Given the spatial overlap between areas treated with TFM and extant populations of O. subrotunda, information on its sensitivity to TFM is needed. This dataset was used to evaluate the acute toxicity of TFM to O. olivaria and O....

These datasets (e.g., 'Starved Rock fish clearing_multi-beam imaging sonar fish data_Pre-clearing_Sonar-s1.csv') include exported information (e.g., fish detection counts) from processed fixed-location multi-beam imaging sonar and mobile side-scan sonar data. Fish abundance in the navigation lock was determined using mobile side-scan surveys, while multi-beam imaging sonars were used to determine fish counts relative to time (i.e., fish per minute). The datasets were used to examine the efficacy of electricity and underwater acoustics, used in tandem, to affect fish abundance (as determined by hydroacoustic data sampling).

Metals are used in primary producer metabolic pathways, such as photosynthesis and the acquisition of macronutrients nitrogen (N) and phosphorus (P), yet we often do not know their potential as limiting nutrients in freshwaters. In the Great Lakes, metals have sometimes been identified as limiting the acquisition of macronutrients, mostly in off-shore waters that are relatively isolated from tributary inputs and sediment interactions. We hypothesized that another area where metals might be important was within harmful algal blooms (HABs). Harmful algal blooms are more likely to occur where N and P loads are elevated due to human activities, but short-term growth assays still often find summer bloom communities are...
