These data are associated with a project to integrate new science and technology into invasive carp control efforts. Mississippi River Lock and Dam 19, located at Keokuk, IA, is an area where sound deterrents are being installed to help keep invasive carp from moving upstream. The data are being used to analyze the lock and dam approach structure.
This dataset includes the behavioral responses to a broadband sound for common carp in an outdoor concrete pond. Broadband sound (0.06 to 10 kHz) has shown potential as an acoustic deterrent for bigheaded carps, but the response of common carp to broadband sound has not been evaluated. Since common carp are ostariophysians, possessing Weberian ossicles similar to bigheaded carps, it is possible that sound can be used as an acoustical deterrent for all three species.
To evaluate how bigheaded carps use a restored backwater habitat, their passages into and out of and residency within a backwater was monitored using acoustic telemetry. This dataset describes the results of this study and was used to compare activity of bigheaded carps between species, at a diel scale, among seasons, and how activity related of environmental conditions. Calculation of passages and residency are available in the thesis of Douglas Schultz (Southern Illinois University, 2006).
A side scan image collected with Humminbird Helix 10 on November 14, 2019. Side scan sonar creates a picture or an image of the riverbed. To generate an image, side scanners measures the strength of how loud the return sonar pings are.
A slope raster generated from multibeam bathymetry and terrestrial lidar collected simultaneously on November 14, 2019. Slope represents the rate of change of elevation under the water column.
