These data are high-resolution bathymetry (riverbed elevation) in compressed LAS (*.laz) format, generated from the July 17–19, 2023, hydrographic survey of Bubbly Creek and various sidings, harbors, and turning basins on the Chicago Sanitary and Ship Canal (CS&SC) in Cook County, Illinois. The survey includes all Bubbly Creek from the confluence with the CS&SC in the north to the Racine Avenue Pump station in the south; various sidings and turning basins along the CS&SC between Kedzie Avenue and South Halsted Street; and the Marine Safety Station harbor near the Chicago Harbor Lock on Lake Michigan. This survey is a continuation and enhancement of the bathymetric survey of the CS&SC in Cook County, Illinois, conducted...
These data are high-resolution bathymetry (riverbed elevation) in compressed LAS (*.laz) format, generated from the July 17–18, 2023, hydrographic survey of the North Branch Chicago River and North Shore Channel in Cook County, Illinois. The survey extends from near the North Avenue Turning Basin and Goose Island in the south, upstream to the Metropolitan Water Reclamation District (MWRD) Wilmette Pumping station in the north. The survey is a continuation of the bathymetric survey of the Chicago River and Chicago Sanitary and Ship Canal (CS&SC) in Cook County, Illinois, conducted August 22–24, 2022 (Huizinga and Rivers, 2023). These data also include an ultra-high resolution resurvey of a large sunken vessel discovered...
Multibeam and sidescan sonar were collected for a total of 15 sites in the North Arm, Maxwell Bay, and St. Albans Bay of Lake Minnetonka, Minnesota, to determine whether hydroacoustics could be used in turbid rivers and lakes as a method of rapid detection for invasive zebra mussel (Dreissena polymorpha) infestations. Hydroacoustic data were collected in June, August, and the end of September, 2022 at all 15 sites. This dataset is composed of bathymetry in the form of digital elevation models and 3D point cloud (in the form of XYZ text file), sidescan sonar image mosaics, and underwater video still images for assessing the detection of Dreissenids using hydroacoustics and underwater video for habitat.
