In this exceptional program, we will go to Mayotte with the scientists who are monitoring the emergence of a gigantic underwater volcano. We will also dive into the seabed to discover these strange gas layers that cause underwater avalanches and tsunamis. Finally, we will stop over on the atolls threatened by rising sea levels. How can we observe and understand these phenomena to better protect ourselves from the risks? 0:00: Summary 4:45: The enigma Youtuber: Castor Mother - / @castormother 8:07: Today's guests: Elodie Fleury (IFREMER) and Gonéri Le Cozannet (BRGM) 17:00: Mayotte has the trembling! - Emmanuel Rinnert (IFREMER) and Isabelle Thinon (BRGM) 36:05: The oceans are gaining height - Gonéri Le Cozannet (BRGM) 46:15: The plastic quiz - Alexandra Chaumonnot (IFPEN) 1:02:44: Oysters and climate change - Elodie Fleury (IFREMER) 1:10:02: High-pressure gas - Vincent Riboulot (IFREMER) 1:22:11: Sargassum hunting - Maurice Heral (ANR) 1:31:50: Let's talk passion 1:36:56: The FDS near you 1:41:31: Thank you all! :) From October 2 to 11, every day at 5:30 p.m., Fred Courant and the Esprit Sorcier team were live to celebrate science! #ScienceEnDirect The Science Festival: https://www.fetedelascience.fr/ #FDS2020 https://www.lespritsorcier.org/ Facebook: /espritsorcier Twitter: /espritsorcier Tipeee: https://www.tipeee.com/l-esprit-sorcier © L'Esprit Sorcier - 2020
