Synopsis

Fragile and translucent, krill are fundamental to the Antarctic ecosystem. Yet, their numbers are plummeting, a decline that continues to perplex scientists. A primary hypothesis suggests that krill’s life cycle is governed by an internal rhythm attuned to the Antarctic ice pack's seasonal changes. As climate change alters the timing of these ice formations, this natural cycle is thrown into disarray. To investigate this, NOVA journeys aboard the Polarstern, a cutting-edge research vessel, to th
