This week at the Meeting of the CCAMLR) in Hobart, Australia, all Member countries have agreed to a joint USA/New Zealand proposal to establish a 1.55 million km2 area of the Ross Sea with special protection from human activities. The new MPA – an area the size of France, Germany and Spain combined – comprises:(
1,117,000 km2 of fully protected marine reserve:
the Ross Sea shelf and slope and the Balleny Islands — see (i) below
Representative protection of areas that provide good samples of special habitats — this includes a seamount (underwater mountain) range — see (ii)
Scott Seamount — see (iii);
a 110,000 km2 special research zone (SRZ) allowing for limited research fishing for krill and toothfish, and;
a 322,000 km2 krill research zone (KRZ) allowing for controlled research fishing for krill.
The Ross Sea is a deep bay of the Southern Ocean in Antarctica, between Victoria Land and Marie Byrd Land. It derives its name from the British explorer James Ross who visited this area in 1841. To the west of the sea lies Ross Island and to the east Roosevelt Island, while the southernmost part is covered by the Ross Ice Shelf, and is about 200 miles (320 km) from the South Pole.
It is one of the last stretches of seas on Earth that remains relatively unaffected by human activities. Because of this, it remains almost totally free from pollution and the introduction of invasive species. Consequently, the Ross Sea has become a focus of numerous environmentalist groups who have campaigned to make the area a world marine reserve, citing the rare opportunity to protect the Ross Sea from a growing number of threats and destruction. The Ross Sea is regarded by marine biologists as having a very high biological diversity and as such has a long history of human exploration and scientific research, with some datasets going back over 150 years.
The Ross Sea is home to at least 10 mammal species, half a dozen species of birds, 95 species of fish, and over 1,000 invertebrate species. Some species of birds that nest in and near the Ross Sea include the Adélie penguin, emperor penguin, Antarctic petrel, snow petrel, and south polar skua. Marine mammals in the Ross Sea include the Antarctic minke whale, killer whale, Weddell seal, crabeater seal, and leopard seal. Antarctic toothfish, Antarctic silverfish, Antarctic krill, and crystal krill also swim in the cold Antarctic water of the Ross Sea.
The flora and fauna are considered similar to other southern Antarctic marine regions. Particularly in Summer, the nutrient-rich sea water supports an abundant planktonic life in turn providing food for larger species, such as fish, seals, whales, and sea– and shore-birds.

This new MPA, to come into force in December 2017, will limit, or entirely prohibit, certain activities in order to meet specific conservation, habitat protection, ecosystem monitoring and fisheries management objectives. Seventy-two percent of the MPA will be a ‘no-take’ zone, which forbids all fishing, while other sections will permit some harvesting of fish and krill for scientific research.
“While this is undoubtedly good news, the agreement on the Ross Sea will expire in 35 years. According to the World Conservation Union (IUCN) guidelines, marine protected areas must be permanent. WWF has concerns that the Ross Sea agreement does not meet this standard,” said Chris Johnson, WWF-Australia Ocean Science Manager. In coming years, WWF will continue to push for the Ross Sea to become a marine protected area (MPA), protected in perpetuity.
CCAMLR Executive Secretary, Andrew Wright, is excited by this achievement and acknowledges that the decision has been several years in the making.
“This has been an incredibly complex negotiation which has required a number of Member countries bringing their hopes and concerns to the table at six annual CCAMLR meetings as well as at intersessional workshops.
A number of details regarding the MPA are yet to be finalised but the establishment of the protected zone is in no doubt and we are incredibly proud to have reached this point,” said Mr Wright.
CCAMLR’s Scientific Committee first endorsed the scientific basis for proposals for the Ross Sea region put forward by the USA and New Zealand in 2011. It invited the Commission to consider the proposals and provide guidance on how they could be progressed. Each year from 2012 to 2015 the proposal was refined in terms of the scientific data to support the proposal as well as the specific details such as exact location of the boundaries of the MPA. Details of implementation of the MPA will be negotiated through the development of a specific monitoring and assessment plan. The delegations of New Zealand and the USA will facilitate this process.
“It has been well worth the wait because there is now agreement among all Members that this is the right thing to do and they will all work towards the MPA’s successful implementation,” Andrew Wright said.
MPAs aim to provide protection to marine species, biodiversity, habitat, foraging and nursery areas, as well as to preserve historical and cultural sites. MPAs can assist in rebuilding fish stocks, supporting ecosystem processes, monitoring ecosystem change and sustaining biological diversity.
Areas closed to fishing, or in which fishing activities are restricted, can be used by scientists to compare with areas that are open to fishing. This enables scientists to research the relative impacts of fishing and other changes, such as those arising from climate change. This can help our understanding of the range of variables affecting the overall status and health of marine ecosystems.
