USV at the coral's bedside - January 2021

On January 11 and 12, 2021, Sylvain BONHOMMEAU, head of the IOT project, visited the island of Europa in order to check the proper operation of the LoRa network and the state of the equipment deployed in September-October 2020 with a view to the deployment of tags on turtles, which will take place in the first half of 2021.

The other objective of this trip was to monitor the state of health of the Europa coral reef at the request of the French Southern and Antarctic Lands using the USV motorised autonomous board. The board was deployed on sites historically monitored by scientists within the framework of the GCRMN (Global Coral Reef Monitoring Network) in order to assess the impact of the last episode of coral bleaching that occurred in 2020.
