As we enter a season of reflection and gratitude, we turn our attention to one of the most awe-inspiring and least explored parts of our planet: the seafloor. In this episode, we’re joined by Steve Hall and Helen Snaith from Seabed 2030, a global initiative working to map 100% of the world’s ocean floor by the year 2030. Together, we explore the importance of ocean mapping for science, conservation, climate resilience, and navigation—and how citizen scientists around the world are playing a surprising and essential role. From submarine canyons to undersea mountains, the ocean floor holds answers to questions we haven’t even thought to ask. Join us as we celebrate the spirit of exploration and give thanks for the ocean’s vast, mysterious depths.
