On 14^th to 19^th September 2021, researchers from the universities of Southampton, Sydney and the Balearic Islands will carry out experiments with different autonomous systems: an Autonomous Underwater Vehicle, an Autonomous Surface Vehicle and a Lagrangian Drifter. The scientific campaign is funded by the Eurofleets+ programme and will be carried out on board the RV SOCIB in the waters of the Marine Protected Area of Cabrera. These different platforms will be deployed to demonstrate in situ capabilities for marine data collection and seabed exploration, targeting endemic seagrass mapping using artificial intelligence. The campaign is under the direction of Dr. Miquel Massot-Campos, from the Ocean Perception research group of the University of Southampton.
