Developmental Stages of Grass Carp (Ctenopharyngodon idella) eggs in the Sandusky River (ver. 3.0, July 2020) Developmental Stages of Grass Carp (Ctenopharyngodon idella) eggs in the Sandusky River (ver. 3.0, July 2020)
Grass Carp Ctenopharyngodon idella was imported to the United States in the 1960s for research into its usefulness as a biocontrol agent for nuisance aquatic vegetation. Escapees and intentionally stocked individuals founded wild, spawning populations in the Mississippi River and tributaries to the Laurentian Great Lakes. USGS-led research on the Sandusky River, a tributary to Lake Erie
Modeled and observed trends at reference basins in the conterminous U.S. from October 1, 1983 through September 30, 2016 Modeled and observed trends at reference basins in the conterminous U.S. from October 1, 1983 through September 30, 2016
This data release contains trend results computed on the basis of modeled and observed daily streamflows at 502 reference gages across the conterminous U.S. from October 1, 1983 through September 30, 2016. Modeled daily streamflows were computed using the deterministic Precipitation Runoff Modeling System (PRMS), and five statistical techniques: Nearest-Neighbor Drainage Area Ratio...
Ecosystem water balance and ecological drought patterns under historical and future climate conditions for the Four Forest Restoration Initiative (4FRI) Landscape Ecosystem water balance and ecological drought patterns under historical and future climate conditions for the Four Forest Restoration Initiative (4FRI) Landscape
These data were compiled for research pertaining to the effects of stand density treatments on growth rates in semi-arid, ponderosa pine forests. Also, these data examined how the planned restoration treatments in the Four Forests Restoration Initiative (4FRI), the largest forest restoration project being implemented in the United States, would alter landscape-scale patterns of forest...
Geospatial bathymetry dataset for the Black River near Great Bend, New York, 2020 Geospatial bathymetry dataset for the Black River near Great Bend, New York, 2020
On August 25, 2020, the U.S. Geological Survey conducted a bathymetry survey of a 550 meter long reach of the Black River near Great Bend, New York. The study reach began approximately 1,000 meters upstream from the State Route 26 bridge in Great Bend, New York. Depth data were collected primarily with a 1,200 kilohertz Teledyne RD Instruments RioPro acoustic Doppler current profiler...
Compilation of Data for Parameterization of an Ecopath Model of Lake Superior at the Beginning of the 21st Century (2001-2016) Compilation of Data for Parameterization of an Ecopath Model of Lake Superior at the Beginning of the 21st Century (2001-2016)
This data release includes tabular data files. The dataset consists of four input data tables (Appendices A1-A4) for a Lake Superior EcoPath with EcoSim (EwE; http://ecopath.org) model parameterized to the early 21st century using 2001-2016 collections. The data presented here are primarily intended to development a static ecosystem model representing a snapshot of Lake Superior circa...
Stormwater-quality data for lined permeable pavement systems in Madison, WI, from September 2016 through July 2018 Stormwater-quality data for lined permeable pavement systems in Madison, WI, from September 2016 through July 2018
This dataset describes water-quality data measured from the parking lot influent and underdrain and overflow effluent from the porous asphalt, pervious concrete, and permeable interlocking concrete paver test plots in Madison, Wisconsin, USA. Data include precipitation statistics; influent, overflow, and underdrain volumes; and concentrations and loads of total and dissolved forms of...
