Semi-Automated Data Processing and Semi-Supervised Machine Learning for the Detection and Classification of Water-Column Fish Schools and Gas Seeps with a Multibeam Echosounder † [PDF]
Sensors, 2021 Multibeam echosounders are widely used for 3D bathymetric mapping, and increasingly for water column studies. However, they rapidly collect huge volumes of data, which poses a challenge for water column data processing that is often still manual and time-

Reconstructing Multibeam Echosounder Bathymetry with Generative Adversarial Networks: Toward Efficient Use of Survey Resources [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information SciencesThe spatial accuracy and resolution of Multibeam Echosounder data are inherently lower than those of high-resolution underwater LiDAR measurements. However, while Multibeam Echosounder provides wide coverage and extensive historical availability, LiDAR ...
