On this week’s show: A boost in research ships from an unlikely source, and how the 2022 Tonga eruption shook earth, water, and air around the world

For decades, the Sea Shepherd Conservation Society caused controversy on the high seas; now it’s turning its patrolling ships into research vessels. Online News Editor David Grimm discusses how this change of heart came about with host Sarah Crespi.

Also this week, how atmospheric waves can push tsunamis around the globe. Producer Meagan Cantwell talks with Emily Brodsky, an earthquake physicist at University of California, Santa Cruz, about data from a multitude of sensors showing how waves in the air drove the fast-moving tsunamis that raced around the planet after the January Hunga eruption in Tonga.
