What's going on there?! In the icy silence of the Antarctic, gigantic holes suddenly appear in the sea ice - phenomena that amaze researchers around the world. These so-called "polynyas" appear without warning and raise questions: What exactly is behind these mysterious openings? Today we're taking you on an exciting journey to solve the mystery of the giant holes. Scientists have discovered that the answer is more fascinating than you can imagine! We'll explain to you how the underwater elevation "Maud Rise" and ocean currents are melting the ice and what role wind and salty water play in this. But it goes even deeper: With the help of seals and their sensors, researchers were able to gain insights for the first time that would otherwise be impossible! And what does all this mean for the future of the Antarctic - and for the global climate? Tune in and be surprised at how Antarctica continues to present us with unexpected puzzles!
