Mile-thick ice. Dry, rocky valleys. Tiny creatures. Red parkas. Seal mummies. We’re going to Antarctica with National Geographic Explorer, microscopic photographer, and Antarcticologist Ariel Waldman. She hosts the gorgeous PBS series “Life Unearthed” and answers a blizzard of questions about camping in the middle of an ice sheet, hauling microscopes to the ends of the Earth, what’s living in a drop of melted snow, potty protocols, microplastics, and the research that happens on a giant continent that carries many mysteries. Also: why you should cold email someone. Like, today. Dwyer Theme song by Nick Thorburn Hosted by Simplecast, an AdsWizz company.
