1. Meetting the people of Mayotte<\/h1>\n\n\n\n

With Marie-Eve, we (Judith and La\u00ebtitia) have been named to go on the ground for the October 5th<\/sup>\u2019 day with Jacques. This national day is dedicated to the resilience in the face of natural disasters (sismic, volcanic, marine submersion, hurricanes etc.), on a people of Mayotte\u2019s territory which face a lot of extreme events. For the scientific team, the goals of this day are to introduce the MAYOBS campaigns and the main results and understanding of the Mayotte\u2019s geology, in reply to researched did after the seismic and volcanic crises in 2018. As students, our aim was to highlight the educational projects carried out on board the ship.<\/p>\n\n\n\n

When we waked-up, around 6am, we alrealdy were in the Mayotte\u2019s lagoon, calm with the presence of some fishers in lakas. The apointment is scheduled at 6.30 am at the gangway leading to the shore. After reaching the Marion anchorage between Petite Terre and Grande Terre, the first shuttle departs with the first part of the group. (Pictures 1 and 2) Our \u00ab\u00a0taxi boat\u00a0\u00bb come 15 minutes later to, at last, to disembark at the Mamoudzou jetty, next to the barges which do return trips with Petite-Terre.<\/p>\n\n\n\n

We arrive under big barnums ordered next to the tourisme office and the covered market, closed this day. On the other side is organised the bi-annual canoe race with a presenter who is fully committed to their role. The scientific team is welcomed with a breakfast featuring chicken samosas and ginger tea (there were also pastries and pancakes \u2013 yum yum!). The stands take place\u00a0: posters, disposition of rocks come from yesterday\u2019s dredging, and preparation of diaporamas or videos. During this time, without going too far, Faymida takes us to enjoy the view on the harbour.<\/p>\n\n\n\n

Around 9.30am, and after have taken some photos in front of the #<3Mamoudzou, the conferences can begin. It is Anne Lemoine who kicks things off with a presentation about the observation of the seismic and volcanic crisis in link with the creation of the new Fani Moare building. We take place at the control room to thin the presentations\u2019 transitions and also to take pictures of the event.<\/p>\n\n\n\n

Presentations follow one after another and come the moment of the introduction of educational projects. The University of Mayotte event begins with personal accounts of their respective experiences and feelings whilst on a scientific mission, with the added bonus of an excerpt from their video clip edited by Aboubacar. Faymida concludes the presentation with a speech in Shimaore (Photo 4, right)<\/strong>.<\/p>\n\n\n\n

It is our turn next, Floating University, to sharing our experience like youg scientists on board of a monitoring campaign. The introduction is short but anables us to intruduce ourselves to the a small audience still present. It is Isabelle wo finish the morning\u2019s conference with a general introduction of the geology around Mayotte. <\/p>\n\n\n\n

Animations migrate to the stands\u00a0: associations, prevention, science\u2026 Some lacals people, alone or in family, are curious and make a detour.<\/p>\n\n\n\n

The BRGM\u2019s stand works well and enable to visualize the sebed throught a mock-up. Next, a Game of the Goose version Game of the Seahorse interess youngs from the island. Finally, the rocks recovered from the dredging are also making an impression, and Marin explains their origin to the small groups.<\/p>\n\n\n\n

The time pass quickly and it is already the time to set off again to the Marion Dufresne, who impress by this size, the same than the little island behind it. The first group go around 3pm and we wait the second boat which takes us back. We\u2019d barely arrived when we found our colleagues in the middle of a treasure hunt! We didn\u2019t want to disturb them; we\u2019d have time to chat later.<\/p>\n\n\n\n

The pilot come back on the ship to enables us to leave the lagoon and we, we enjoy the start to say good bye at the island, which we\u2019ll see only from far whilst admiring the sunset on the deck.<\/p>\n\n\n\n

2) Under the lagoon\u2019s sun (on board)<\/h1>\n\n\n\n

With Lucie, we wake up at 4am. During that someone are finishing their watch or are going to bed, we are getting ready to attend the arrived of the Marion Dufresne in the Mayotte\u2019s lagoon, on the occasion of the Resilience\u2019s day organised this October 5th<\/sup>. The pilot-boat comes on time, 5am, and the pilot comes aboard whereas the ship continues to navigate. An unforgettable experience! We have the luck to watch a superb sunrise, around 5.45am, a rare and privileged moment (but not for everyone!), shared with some courageous people already on the boat.<\/p>\n\n\n\n

Upon entering in the Mayotte\u2019s lagoon, the spectacle is breathtaking: turquoise waters, a golden light\u2026but also a little smell of burning which is surprising. It comes frome the slash-and-burn farming, still practicated on the island, like said during the Seminary 2<\/a>. Around 7.30am, the navire drop the anchor in the Mamoudzou\u2019s bay. The 24 participants to the day on the ground wait to board the water taxi, which is accessed from the sea via a very steep ladder \u2013 a little aventure in itself!<\/p>\n\n\n\n

During that Judith and La\u00ebtitia take part of the activities on the ground, other students take advantage to catch up on a few hours\u2019 sleep or try to make progress with their work (writing seminar papers, revising, etc.). We even get to watch canoe races \u2013 a moment that\u2019s as spectacular as it is unexpected!<\/p>\n\n\n\n

After the lunch, the atmosphere relaxes on board: a treasure hunt is organised by Clo\u00e9 and Lisa, two PhD students from the dredging team. Two teams face off: The Marine Worms and the Goldfishes. After a fiercely contested match, particularly after battling through the rough terrain, victory went (unsurprisingly!) to the Marine Worms!<\/p>\n<\/div><\/div>\n\n\n\n

\n

By their side, some students roll up their sleeves and lend a hand to the crew, in between activities (Picture 11)<\/strong>. During the end of the day, at 4pm, an appointment is made at the Science PC for a guided tour of the ship. Some spaces are introduced \u2013 an immersion you can discover in the section Crews on board<\/a><\/strong><\/em>.<\/p>\n\n\n\n
