Wildlife-rich areas of the seas around Antarctica which were identified in recent submarine dives have been approved for special local protection.
Four "vulnerable marine ecosystems" were identified during an expedition by greenpeace along the waters of the Gerlache Straight along the Antarctic Peninsula and in the Antarctic Sound earlier this year.
An underwater world rich in corals, sponges, ice fish, star fish and sea squirts have been revealed ion the seafloor in video evidence collected by Dr Susanne Lockhart, of the California Academy of Sciences, during trips in a submersible.
Footage of these little-seen Antarctic seafloor nature systems was proposed as evidence of sites in need of protection to a working group of scientists at the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR).
A protected area of one nautical mile around the sites will be established at the next meeting of countries under CCAMLR in October with scientists recommending them for formal registration, Greenpeace said.
Dr Lockhart said: “I’m extremely pleased and excited about getting these areas protected. The video evidence collected during this expedition is full of rare and little known organisms.
“The seabed around Antarctica truly is a wonderland of biodiversity that is at serious risk from the combined effects of over-fishing and climate change.
“We need to protect this wondrous place before we lose what we don’t even know we have.”
Oscar -winning actor Javier Bardem dived into the role of Antarctic Ambassador with Greenpeace calling the wildlife "breathtaking", he said: “Humanity’s footprint weighs heavy on so much of our shared planet, but this year we have an opportunity to create a vast Antarctic Ocean sanctuary and protect this stunning wilderness for generations to come.”
Greenpeace is campaigning for a network of protected areas in the Antarctic, including a vast 694,984 square mile (1.8 million sq km) Antarctic Ocean sanctuary in the Weddell Sea which would be the largest protected area on Earth.
John Hocevar, a Greenpeace marine biologist who piloted the submarine and co-authored the report with Dr Lockhart, said: “It was amazing to see the diversity and abundance of life in these colourful, alien, seafloor landscapes and I’m thrilled that, because of our expedition, they will now be protected.
“We know so little about these remote waters that there is a precautionary imperative to protect them, before we damage or destroy ecosystems we haven’t even had a chance to study yet.
“Our findings add to the growing body of evidence for why we need a network of ocean sanctuaries in the Antarctic.”
