Scientists from a number of institutions collaborated to collect data on 17 marine birds and mammals such as penguins, albatrosses, seals and whales in the ocean around Antarctica
are changing the world’s oceans and that certain key areas need to be protected. But identifying these areas is difficult, especially in the most remote waters on Earth.
“Predators are very good at identifying and targeting productive areas. If whales, seals and penguins are all going to the same area, that’s where you’ll find a high abundance and diversity of species,” said Nelson Mandela University’s Pierre Pistorius, who heads up a South African National Antarctic Programme project tracking marine predators at Marion Island.
The areas identified as “areas of ecologically significance” are scattered around the sub-Antarctic islands in the Indian and Atlantic Oceans, and over the Antarctic continental shelf. “It’s important that we keep monitoring the physical and biological properties of the Southern Ocean so we can manage MPAs in a dynamic way. For instance, we may need to be flexible with MPA boundaries.”
