Meet Valentine, a submarine volcanologist aboard OceanXplorer from our latest mission in Mayotte, who’s mapping the seafloor and decoding how these underwater volcanoes reshape entire ecosystems. Imagine lava erupting underwater—hitting seawater that’s 1,000°C cooler. That’s the kind of deep-sea science we're here to witness. Fun fact: Did you know that most volcanic activity on Earth is underwater? Few ever get to see it up close. But we’re changing that. | OceanX
