This week, I gave a TEDx talk on listening to the ocean’s climate clues. A few days later, I found myself underwater doing exactly that—though not quite how I expected.
We captured a fin whale call on a GoPro while diving near Nice. Estimated ~5 km away. Wild.

ExoCean is in #Bermuda! Or at least most of it is (sorry @sulpis.bsky.social). We're here looking for foraminifera to grow in the lab, and sediments to observe how they will react to ocean change.

The thing about early alteration of grains in the sediment, is that there are a lot of things living there. So, while chemistry is what's working on the fundamental level, (micro)biology is a critical mediating factor. 🧪⚒️
