Data release associated with research that describes how major flooding and dam operations in the upper Mississippi River contribute to large upstream migrations of native paddlefish and invasive bigheaded carp Data release associated with research that describes how major flooding and dam operations in the upper Mississippi River contribute to large upstream migrations of native paddlefish and invasive bigheaded carp
Recent research has attributed major flood events with the upstream spread of invasive carp in the Mississippi River. In two sequential years, the upper Mississippi River experienced a low water year with very minimal flooding in 2022 and a very high water year with extreme and sustained flooding in the spring of 2023. This data release contains hydrologic data from the U.S. Army Corps...
Bedload estimated using hydrophones, Trinity River, California Bedload estimated using hydrophones, Trinity River, California
The U.S. Geological Survey (USGS) installed acoustic bedload monitoring systems at four sites along the Trinity River below Lewiston Dam to record the noise generated by mobilized bed material, known as sediment generated noise (SGN) (Geay and others, 2017). The four sites are: Trinity River at Lewiston (TRAL, 11525500), Trinity River above Grass Valley Creek (TRGVC, 11525630), Trinity...
Crayfish densities in relation to concentrations of metals in sediment and water in Madison County, Missouri, 2004-2015 Crayfish densities in relation to concentrations of metals in sediment and water in Madison County, Missouri, 2004-2015
Data was collected during a series of studies that assessed the effects of metals on crayfish in mining districts in Missouri. Adult crayfish were collected in riffles to determine whether crayfish densities were lower at sites downstream of mining areas compared to sites upstream of mining areas. Metal concentrations in surface or pore water and less than 2-mm sediment were measured and
Sea-level rise and high tide flooding inundation probability and depth statistics at Biscayne National Park, Florida Sea-level rise and high tide flooding inundation probability and depth statistics at Biscayne National Park, Florida
This dataset includes elevation-based probability and depth statistics for estimating inundation under various sea-level rise and high tide flooding scenarios in and around the National Park Service’s Biscayne National Park. For information on the digital elevation model (DEM) source used to develop these datasets refer to the corresponding spatial metadata file (Danielson and others...
Chronic toxicity of metals in two water hardness to three sizes of the crayfish Faxonius quadruncus Missouri, USA 2017-2018 Chronic toxicity of metals in two water hardness to three sizes of the crayfish Faxonius quadruncus Missouri, USA 2017-2018
Laboratory studies were conducted to examine the effect of water hardness and age of crayfish on the toxicity of environment-based metals mixture. Additionally, the effects of chronic exposure to a metals mixture to egg development in adult F. quadruncus were assessed. Mortality and growth of F. quadruncus were assessed. These data consist of attributes of water quality from toxicity...
Effects of metals from historical mining on crayfish in Madison County Missouri USA, 2015 Effects of metals from historical mining on crayfish in Madison County Missouri USA, 2015
Deposits of lead (Pb) and other metals in southeastern Missouri, USA have been exploited since the 1700s. Metal contamination of fish and other aquatic biota, alteration of fish and invertebrate communities, and public health advisories against human consumption of Pb-contaminated fish have resulted. The Little Saint Francis River (LFSR) and its tributaries, which drain the mining...
