GeoTalk: Meet Marie Cavitte, policy officer for the Cryosphere Division, member of the EGU Climate Hazards Task Force, former Blue Book trainee

Welcome, Marie! Could you please introduce yourself to our readers? Hi, my name is Marie Cavitte. I’m a glaciologist and climatologist with a passion for the polar regions. I spent 10 years studying Antarctica. I started off during my Masters, then PhD, looking at the oldest ice on Earth, hunting for THE region of the ice sheet that might contain million-year-old ice. An ice core has been drilled since and all initial results indicate that we hit the target spot-on …


From Signals to the Sea: Building an AI Sound Library for the Ocean

We chatted with Bram Cuyx, an underwater acoustics AI research engineer at the Flanders Marine Institute (VLIZ) in Belgium, about his unique path from engineering into marine science. In this interview, he shares how he made the leap from signal processing in electronics to listening to the soundscape of the North Sea, what it’s like to build a sound library for AI, and why acoustics might be the key to better understanding and protecting marine ecosystems. Discover the challenges, surprises, …
