Acoustic Point Cloud of Bubble Plumes in the Downstream Approach to Peoria Lock, Near Peoria, Illinois, During Testing of an Automated Barge Clearing Deterrent, September 12, 2022

Metadata Updated: July 6, 2024

A variety of new technologies are being evaluated to mitigate the spread of invasive carps from the Illinois River to the Great Lakes. In 2022, the U.S. Army Corps of Engineers, U.S. Fish and Wildlife Service, and U.S. Geological Survey undertook a field-scale interagency study to determine the efficacy of an Automated Barge Clearing Deterrent (ABCD) in flushing live fish away from commercial barge vessels entering Peoria Lock on the Illinois River. The ABCD is a forced air manifold system that is placed at the channel bed to create a longitudinal array of bubble plumes. In support of this study, a multibeam echosounder mapping system (MBMS) with integrated inertial navigation solution (INS) mounted on a manned survey vessel was used to observe the water column while the ABCD was operating on September 12, 2022. The bubbles in the water column generate a strong enough acoustic reflection that they are registered by the MBMS as a bottom return. The result is a three-dimensional (3D) point cloud that qualitatively shows the shape and extent of the underwater bubble plumes generated by the ABCD. It is important to emphasize the qualitative nature of these observations and that these data are not the equivalent of a visual image of the bubble plumes. This page contains an LAS file with the full 3D point cloud showing the observations of the bubble plumes and a thumbnail image with a basic visualization of these data.
