The Algae That Thrive in Arctic Darkness
Microalgae are tiny organisms that convert energy from sunlight into fuel. The arctic ecosystem depends on them. In springtime, the algae bloom brilliant shades of green and draw tiny crustaceans, fish, birds and more to arctic waters. But what happens in wintertime, when the sun goes down and darkness reins for months? In the depths of the polar night, biogeochemist Clara Hoppe has found evidence that some microalgae are still ready to photosynthesize. Today on the show: how tiny microalgae limbo for their lives and come out more powerful than scientists ever imagined.
