Sedimentary Data from the Coastal Marshes Fringing the Lower Waccasassa River, Northwest Florida
The Waccasassa River is located in a small watershed situated along the middle section of the low-gradient, low-energy, sediment-starved Big Bend coast in west central Florida. The river mouth empties into the head of the shallow, microtidal Waccasassa Bay and the Gulf of Mexico. The lower end of the river and the surrounding coastline are dominated by coast-parallel Juncus roemerianus salt marshe
Data collected in 2008-2014 to assess nearshore subtidal community response to increased sediment load during removal of the Elwha River dams, Washington State, USA
Data are time series of substrate grain size, remotely sensed water column turbidity, and measures of abundance (e.g., density, percent cover) of the nearshore subtidal (3-17 m depth) benthic community (vegetation, invertebrates, and fish) collected before (2008-2011) and during dam removal (2012-2014).
Primary production across a coastal wetland landscape in Louisiana, U.S.A. (2012-2014)
Above- and belowground production in coastal wetlands are important contributors to carbon accumulation and ecosystem sustainability. As sea level rises, we can expect shifts to more salt-tolerant communities, which may alter these ecosystem functions and services. Although the direct influence of salinity on species-level primary production has been documented, we lack an understanding of the lan
Direct-push sediment cores, resistivity profiles, and depth-averaged resistivity collected for Platte River Recovery and Implementation Program in Phelps County, Nebraska
The U.S. Geological Survey (USGS), in collaboration with the Platte River Recovery and Implementation Program, collected capacitively coupled (CC) resistivity data and six direct push sediment cores to identify the coarsest alluvial deposits underlying the Morse properties in central Nebraska to supplement the subsurface geologic information, for the purposes of proper siting of intentional rechar
Field data used to support hydrologic modeling for the U.S. Geological Survey's San Francisco Bay Area "BALT1" landslide monitoring site
This Data Release includes information used to support numerical simulations of variably-saturated flow focused on measurement-based variability in soil-water retention properties for the U.S. Geological Survey's San Francisco Bay Area "BALT1" landslide monitoring site in the East Bay region of California, USA (see Thomas et al., 2018). The eight datasets are: (1) geologic and instrumentation logs
Organic Carbon Data in Water Samples from Minnesota Lakes, 2012 to 2013
The sampling of three hydrologically diverse Minnesota Lakes (Williams Lake, Shingobee Lake, and Lake Manganika) took place during the years of 2012 to 2013. Water samples were collected and filtered in the field using 0.45 micrometer capsule filters (Versapor membrane), silicon tubing, and a peristaltic pump. Water samples were then shipped on ice to the U.S. Geological Survey in Boulder, Colorad
Emerging fungal pathogen Ophidiomyces ophiodiicola in wild European snakes
Snake fungal disease (SFD) is an emerging disease of wild snakes in eastern North America caused by the fungus Ophidiomyces ophiodiicola. Recently, the disease has also been detected in wild snake in Europe. The data presented here describe: 1) culture, PCR, and histopathology results of wild European snakes opportunistically sampled for O. ophiodiicola, 2) colony expansion rates of various isolat
Environmental conditions synchronize waterbird mortality events in the Great Lakes: Data
During 2010 to 2013, waterbird mortality surveillance programs used a shared protocol for shoreline walking surveys performed June to November at three areas in northern Lake Michigan. Timing (to day) and location (to transect) of carcass deposition and species affected were summarized. Using these observations, the broader goal of our study was to quantify the spatial synchrony of avian mortality
Streambed sediment data for Missouri and Niobrara Rivers, Nebraska and South Dakota, 2015
Deltaic sand deposits at the head of Lewis and Clark Lake, Nebraska-South Dakota were investigated for suitability for use as a proppant feedstock resource in unconventional oil or gas production. The physical characteristics of the deposits are described in four supplemental data sets in varied file formats. First, for the direct-push cores collected at four sandbar complexes in the Missouri Rive
Groundwater data for Washington
Data from wells, springs, test holes, tunnels, drains, and excavations in Washington; well location data includes information such as latitude and longitude, well depth, and aquifer. Groundwater level data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.
Water-quality data for Washington
Chemical, physical, and biological properties of water, sediment, and tissue samples from Washington. Water-quality data are collected as either discrete field measurements or as continuous time-series data from automated recorders that continuously record physical and chemical characteristics including pH, specific conductance, temperature, and dissolved oxygen.
Groundwater Seepage Measurements in Northeast Section of Bear Lake, Muskegon County, Michigan, October 2015
Five discrete groundwater seepage measurements were collected to make a direct measurement of the flux of water across the sediment-water interface. Change in volume/time is the volumetric rate of flow. The volumetric rate of flow was used to calculate flux velocity (distance/time), by dividing the specific area of the seepage meter (2.70-square-feet). The change in volume over the time the seepag
