“The last ocean” is what scientists from all around the world call this deep bay that runs along the edge of Antarctica between Marie Byrd Land and Victoria Land. Since 2016, the world’s largest marine protected area has been keeping this last marine ecosystem intact. The theatre of the most impressive expeditions, it was discovered by James Clark Ross between 1839 and 1843. It was then that he discovered the enormous ice barrier formed by a gigantic ice shelf extending out to the open sea and from which titanic icebergs are calved. One third of the world’s Adelie penguin population lives in the area where this barrier breaks into icebergs. The currents maintain polynyas there, vast areas of persistent open water surrounded by sea ice. These give the penguins access to food. You may also get the chance to spot Ross seals, one of the rarest protected species in the Antarctic.
