✧ blue petrel ✧

The blue petrel (Halobaena caerulea) is a small seabird in the family Procellariidae, the only member of its genus. It is distributed across the Southern Ocean but breeds at only six known sites, all close to the Antarctic Convergence zone. Its plumage is predominantly blue-grey, with an "M" banding across its top, ...

French expedition sets sail to preserve Antarctica's 'invisible wealth'

French explorer Jean-Louis Etienne and his crew of eight scientists this week began an expedition to the remote waters of Antarctica, where they hope to gather a wealth of data to demonstrate the benefits of creating protected areas in the icy continent's rich seas.

We, scientists, activists, and sailors from the #UnderThePole#MaliziaExplorer #expedition, joined by citizens across the globe, call on our governments to do everything possible to protect #Antarctica and the #SouthernOcean. This must begin with the establishment of a #MarineProtectedArea known as #Domain1, in the #WesternAntarcticPeninsula.
