BEEP scientists were again present in this year's edition of Immersion Science, which took place March 27 at Ile Tudy, in southern Brittany. William Johnson and Riwan Leroux gave a conference about the biodiversity of the deep ocean and how to access it to 60 high-school students. In the afternoon, the students were introduced to the Deep Sea Spy platform, where they learned how to recognize groups of key organisms from hydrothermal vent observatories.
