Mystery Beneath the Ice

Season 43 Episode 3 | 53m 41s | CC

Tiny, transparent, and threatened, krill are crucial to the Antarctic ecosystem. But the population of krill is crashing for reasons that continue to baffle the experts. A leading theory says that krill’s life cycle is driven by an internal body clock that responds to the waxing and waning of the Antarctic ice pack, but climate change alters the timing of the ice pack, disrupting their life cycle.
