Glaciers: Where are they? What are they made of? What happens when chunks splinter off into the sea? There are ICEQUAKES? CalTech Cryoseismologist Celeste Labedz sometimes wears a cape with her snowpants and spends part of her career shooting explosions into giant chunks of ice and recording the seismic activity, analyzing the rivers that flow through glaciers, and keeping tabs on glacial melt. Also discussed: the most goth way to honor a glacier, and whether or not you should visit them IRL.
