        Mystery Beneath the Ice | Phytoplankton and Krill

        Learn about a key defining feature of the Antarctic ecosystem—sea ice, and glimpse what the sea ice environment is really like, in this video from NOVA: Mystery Beneath the Ice. Travel along on the research ice breaker vessel, Polarstern, as it sails through the treacherous, iceberg-laden waters of the Southern Ocean. Hear scientists describe the link between annual variations in sea ice and populations of krill, which are fundamental to the Antarctic food web.
