Protecting Antarctica's Southern Ocean

Antarctica’s Southern Ocean is one of the world’s last great wilderness areas, surrounding the coldest, driest, windiest, and least altered continent.

The ocean’s frigid waters bustle with thousands of species found nowhere else, from brilliantly hued starfish and bioluminescent worms to pastel octopuses. Nutrients that well up from the icy depths ride currents great distances to nourish wildlife in faraway seas.

Antarctica is also home to millions of penguins that feed on large swarms of krill, a tiny shrimplike crustacean, and other forage species in the region’s delicate food web.

But those predator-prey relationships are in jeopardy, scientists say, in large part because the Southern Ocean ecosystems are being modified by the impacts of climate change. Temperatures there are warming faster than nearly anywhere else on Earth.

To protect this spectacular region and the species that rely on it, Pew and its partners are working with the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR)—the body responsible for conserving biodiversity in the Southern Ocean—and its member governments to establish a network of large-scale marine protected areas (MPAs) around Antarctica.

The Southern Ocean, surrounding Antarctica, is one of the least altered marine ecosystems on Earth. Scientists believe this ecosystem is changing due to the impact of climate change and temperatures that are warming faster than nearly anywhere else on Earth.

In the waters off East Antarctica, the MacRobertson, Drygalski, and D’Urville Sea-Mertz areas cover almost a million square kilometres. Together, they make up the current proposal for a system of marine protected areas (MPA) to be considered by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR).

Protections for the Antarctic Peninsula Are Critical for Marine Life

Issue Brief

The waters off the western Antarctic Peninsula and the Scotia Sea are home to diverse and abundant marine life. People who travel to this region are likely to encounter orcas and humpback whales, fur and crabeater seals, and some of the 1.5 million pairs of Adélie, chinstrap, and gentoo penguins that nest and forage there. But they are unlikely to spot what these species depend on for survival: huge swarms of the tiny shrimplike crustaceans called Antarctic krill.

Fact Sheet

The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) is considering a proposal that would create a marine reserve in the Weddell Sea covering 700,000 square miles (1.8 million square kilometers). The Weddell Sea is a remote, ice-covered embayment east of the Antarctic Peninsula, and one of the most pristine marine ecosystems in the world. This area is a unique habitat known for its outstanding biodiversity, including Antarctic petrels, emperor and Adélie penguins, and multiple species of seals and whales. Far below the sea ice, nutrient-rich benthic ecosystems form key habitat for an array of creatures found nowhere else on Earth, such as glass sponges and cold-water corals.
