Pesticide Concentrations Measured During In-Situ Active Water Sampler Testing in Solano County, California, 2023 Pesticide Concentrations Measured During In-Situ Active Water Sampler Testing in Solano County, California, 2023
A novel U.S. Geological Survey-developed active water sampler was deployed at Ulatis Creek in Solano County, California for 24 hours from November 15, 2023 to November 16, 2023. Discrete surface water samples were collected at the start and end points of the active water sampler deployment interval for comparison to the active water sampler. Samples from the active water sampler and the...
Pesticide concentrations in multiple stream matrices collected near Mead, Nebraska, 2022 Pesticide concentrations in multiple stream matrices collected near Mead, Nebraska, 2022
The AltEn bioenergy plant (Mead, Nebraska, USA) previously (2015 to 2021) generated ethanol from almost 100% unused/expired treated corn seeds. This use of treated corn seeds as a feedstock for ethanol production resulted in accumulation of large amounts of contaminated wastewater and solid residue at the plant, a portion of which was applied to surrounding farmland. To better understand...
LUCAS model estimates of forest ecosystem carbon dynamics in California under different initial conditions scenarios LUCAS model estimates of forest ecosystem carbon dynamics in California under different initial conditions scenarios
This dataset provides tabular data output from a series of modeling simulations for forest ecosystems of the U.S. state of California under different initial conditions scenarios. We used the LUCAS state and transition simulation model with carbon stocks and fluxes based on the Carbon Budget Model of the Canadian Forest Sector (CBM-CFS3) to simulate changes in forest ecosystem carbon...
Examining the soundscape at a navigational lock (Lock 19, Keokuk, IA) Examining the soundscape at a navigational lock (Lock 19, Keokuk, IA)
In this study, passive acoustic monitoring was conducted at Lock No. 19 near Keokuk, Iowa on the Upper Mississippi River between 20 June – 26 August 2019 to coincide with peak navigation use. Sound pressure levels were calculated from .wav files collected with passive SoundTrap hydrophones at six locations in the downstream lock approach. This data set consists of the location and...
Geochemical and Mineralogical Data from Legacy Mine Land Sites in Central Colorado, 2019 - 2020 Geochemical and Mineralogical Data from Legacy Mine Land Sites in Central Colorado, 2019 - 2020
This U.S. Geological Survey (USGS) data release contains data from stream water, groundwater/springs, and sediment samples collected from legacy mine land (LML) sites in central Colorado. The sites were selected using a GIS-based approach that integrated regional geological and geochemical datasets with known mine features and satellite data identifying hydrothermal alteration (ASTER) to...
Impacts of bird predation on the detection of acoustic telemetry tags in fish Impacts of bird predation on the detection of acoustic telemetry tags in fish
Note: this data release has been superseded by version 2.0, available here: https://doi.org/10.5066/P14P7RT6. This data release contains the methodology and results of two field experiments performed in 2024 to better understand how predation impacts detection efficiency of acoustic tags. The first experiment was a static approach focusing on how different tag types, tag power, depth...
