We've just arrived on the Canary Islands. What a joy to finally find the long-awaited sun! A few days of stopovers at Peniche and a 9-day crossing have passed since the last newsletter. Once again, the crew has been hard at work!
On the science front, we're not losing sight of our plankton and its relationship to its environment: 🐟 Observation of the Portuguese seabed with the KOSMOS camera! These data are currently being processed by the crew, who are preparing to send them to Konk Ar Lab and IFREMER for further analysis of the results. 🧬 A dozen manipulations with the new plankton net (HSN) whose prototypes we are testing on board were carried out at sea. These harvests enabled three genetic measurements using the Lamprey and six microscopies, including one at night using the Curiosity. These instruments were supplied and designed by Plankton Planet, which will analyze the samples on return from the expedition. ☀️ A PAR sensor at the top of the mast measures the amount of sunlight available to surface plankton for photosynthesis. These particular plankton are responsible for over 50% of the oxygen we breathe! These data are sent to the MISCLab laboratory and submitted to NASA's SeaBASS database.
Here's what's new on the outreach front: ✏️ A new school has joined the four others already following the crew on the adventure! It's the Domblans elementary school in the French Jura. It now receives personalized news from the crew and monthly challenges linked to our missions. Next challenge: come up with a way to make their school more environmentally friendly. Stay tuned! 🧐 Our expedition is part of the Sciences marines à l'école project initiated by Le Temps des Sciences and Guillaume Le Guen, which aims to introduce oceanography and the scientific approach to several classes of 9-year-olds. Pupils analyze and exploit ocean data from four expeditions, including our own! A privileged contact is planned between the crew and these youngsters through written and video exchanges. 🎨 Adventure inspires artists! Christophe Monteil's new work can be seen on our website, here. The dizzying volcanic cliffs of the Canary Islands speak to Bernard Garo, for whom we collect sediments, water, magnificent images of planktonic life and geological traces. This will be the raw material for future works, integrating the DNA of the place in the service of an environmental message on the expedition's return.
🧹 As part of our Wings of the Ocean label, we carried out our first waste collection on a Portuguese beach. Find out more in the Iodine Anecdote section of this newsletter. ⬇️⬇️⬇️
⛵️ And what about the Portugal-Canary crossing? We covered over 1,000km in nine days in ideal conditions... or almost! We were so short of wind that we drifted without sail for a day and two nights. For us, it was an opportunity to do some science, learn how to navigate by the stars, think about reducing our environmental footprint and fill our eyes with wonder at the sight of our first flying fish and sea turtles. The crew also had time to feed their minds with societal podcasts, ink-blackened pages, devoured books and passionate discussions between two loads of seawater laundry and two ukulele tunes.
🔈 During this disconnected time, the maritime magazine Chasse-Marée put us in the spotlight on these social networks.
📍 Next step: south of the Tropic of Cancer to Cape Verde!
