Multibeam bathymetry from an Autonomous Underwater Vehicule (AUV) - Pointe-des-Monts (2019-2020)
Using an autonomous underwater vehicle (HUGIN) equipped with an EM2040 multibeam echosounder, submarine canyons and channels offshore Pointe-des-Monts were surveyed in 2019 and 2020. This survey aimed at identifying the fine-scale morphological variability of turbidity current bedforms on the modern seafloor. This project was funded by Réseau Québec-Maritime. You can see the forthcoming article below.
