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.

A digital elevation model generated from multibeam bathymetry and terrestrial lidar collected simultaneously on November 14, 2019.

A digital elevation model hillshade generated from multibeam bathymetry and terrestrial lidar collected simultaneously on November 14, 2019. A hillshade is a grayscale 3D representation of a surface.

A backscatter raster generated from multibeam bathymetry and terrestrial lidar collected simultaneously on November 14, 2019. Backscatter is the reflection of a signal and can help when determining bottom types. Harder bottom types (like rock) reflect more sound than softer bottom types (like mud), and smoother bottom types reflect more sound than rugged bottom types.

Suspended particles are an essential component of large rivers influencing channel geomorphology, biogeochemical cycling of nutrients, and food web resources. The Upper Mississippi River (UMR) is a large floodplain river that exhibits pronounced spatiotemporal variation in environmental conditions and biota, providing an ideal environment for investigating dynamics of suspended particles in large river ecosystems. Here we investigated two questions: (1) How do suspended particle characteristics (e.g., size and morphology) vary temporally and spatially? and (2) What environmental variables have the strongest association with particle characteristics? Water sampling was conducted in June, August, and September of...

This dataset accompanies the article "Upstream experience and experimental translocation of invasive bigheaded carps results in increased upstream passage success at a navigation lock in a large river". The data come from the experimental capture and tagging of invasive bigheaded carp with acoustic transmitters and physically moving some groups farther downstream. These transmitters emit signals that are detected and recorded on receivers that are strategically placed above, within, and below Mississippi River Lock and Dam 19 (LD 19). Once the data from the receivers were downloaded, we could show when successful upstream passage through LD19 occurs and compare the origin of the fish and the physical characteristics...
