Bathymetry and Velocity Data from Surveys at Highway Bridges crossing the Missouri River in Kansas City, Missouri, in August 2019, August 2020, and October 2020 Bathymetry and Velocity Data from Surveys at Highway Bridges crossing the Missouri River in Kansas City, Missouri, in August 2019, August 2020, and October 2020
These data are high-resolution bathymetry (riverbed elevation) and depth-averaged velocities in ASCII format, generated from hydrographic and velocimetric surveys near highway bridge structures over the Missouri River in Kansas City, Missouri, in August 2019, as well as special surveys at two of the sites in August and October 2020 before and after installation of scour countermeasures...
Sediment grain size, geochemistry, and polychaete functional traits of Norfolk Canyon (western Atlantic) axis, hard substrate, and adjacent slope habitats, 2012-2013 Sediment grain size, geochemistry, and polychaete functional traits of Norfolk Canyon (western Atlantic) axis, hard substrate, and adjacent slope habitats, 2012-2013
Dataset of sediment geochemistry, water column parameters, and macrofaunal functional traits associated with sediment communities collected in Norfolk Canyon axis, hard substrates, and adjacent slope habitats in 2012 and 2013.
Peak-flow frequency analysis for two selected streamgages in the Fourmile Creek Basin in central Iowa, based on data through water year 2018 Peak-flow frequency analysis for two selected streamgages in the Fourmile Creek Basin in central Iowa, based on data through water year 2018
This data release presents peak-flow frequency analyses by the U.S. Geological Survey that were based on methods described by Eash and others (2013) for streamgages 05485605 Fourmile Creek near Ankeny, Iowa, and 05485640 Fourmile Creek at Des Moines, Iowa. These methods are used to provide estimates of peak-flow quantiles for 50-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual...
Survival and ancillary data associated with Cisco acoustic tagging experiment conducted in 2018 and 2019 Survival and ancillary data associated with Cisco acoustic tagging experiment conducted in 2018 and 2019
These data include survival information for Cisco in the laboratory for up to 30 days after surgical implantation of two different sizes of Lotek acoustic tags. Three-hundred fish of a range of sizes were used for the implantation and controls of this experiment, which was repeated three time. Ancillary data of surgical condition, recovery, and time until death or tag expulsion were also...
Hawaiian Islands Hawaiian Hoary Bat Genetic Sexing 2009-2020 (ver. 6.0, January 2021) Hawaiian Islands Hawaiian Hoary Bat Genetic Sexing 2009-2020 (ver. 6.0, January 2021)
We tested the utility of a protocol using genetic markers that previously proved successful to identify the sex of Vespertilionid bats on tissues collected from live bats and carcasses of varying age from the Hawaiian hoary bat (Lasiurus cinereus semotus). This molecular method is based on genes unique to X and Y chromosomes in mammals and previously was used successfully on North...
Extended Seasonal Discharge Records for Selected Streamgage Sites in the Fortymile River Basin, Alaska, 1976-2020 Extended Seasonal Discharge Records for Selected Streamgage Sites in the Fortymile River Basin, Alaska, 1976-2020
Daily mean discharge is needed for water resource management of selected streams in the Fortymile River Basin. The U.S. Geological Survey, in cooperation with the U.S. Bureau of Land Management, developed a technique for estimating seasonal discharge at two short-record streamgage sites in the basin and evaluated the accuracy of the estimated records. Daily mean discharge values were...
