Science in Action (Part 3) 🦭😅🌊
Fieldwork isn’t always predictable—sometimes nature pushes back.

During one of our dives, a sea lion (with backup from the whole family!) got a little too curious—and ended up chasing off our diver. One of the coring tubes was lost to the sea floor forever. You can even see the dramatic entry in the field notebook. And sea lions sunbathing —completely unbothered. They’re used to hanging around fishing boats, often hoping for a snack.

Science in Action (Part 1) 🌊🛶☀️
From November to January, I swapped the French winter for Peruvian summer—joining an international team from France, Peru, and Brazil to sample sediment cores in Paracas Bay.

Our days started at sunrise, heading out by boat to retrieve these precious records of the past. Fieldwork meant multitasking under pressure, adapting to new ways of working, and learning from the diverse perspectives. It’s a reminder that science isn’t just about data—it’s deeply human.

Now, back in the lab, we’re analyzing tiny foraminifera fossils preserved in the sediments to reconstruct 2,500 years of climate history. These microfossils hold clues to how the ocean and atmosphere have changed—and what that might mean for our planet’s future.

How James Hutton paved the way for Darwin’s work

How trees stabilize soil😯
A drawing of the root structure of a pine/fir tree. This is why recently burned land is so unstable once the trees are gone and stop actively stabilizing the soil and simply rot in place. So delicate of a structure.
Imagine what the subsurface root structuring looks like in an active forest or prairie land.
Kind of mind boggling how important plants are to soil development and their loss to soil erosion.

All of those roots are storing carbon—like crazy. "The Earth’s soils contain about 2,500 gigatons of carbon—that’s more than three times the amount of carbon in the atmosphere and four times the amount stored in all living plants and animals." https://lnkd.in/emw6wJKf

The world's soils are the best we have— is one of the best ways to tap its potential.
