A high-resolution sidescan image of the Mississippi River, Lock and Dam 19 approach (downstream) was collected with a Humminbird Solix. Side-imaging sonar creates an image of underwater riverbed features by measuring the intensity of acoustic reflections. This mega side-imaging sonar data was collected and mosaicked to capture more detailed information on the condition of the lock approach to provide information for the construction and deployment of an underwater acoustic deterrent system.
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.
