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.

环绕南极洲的南大洋是地球上受人类行为影响程度最小的海洋生态系统之一。南大洋面积占世界海洋的 15%,拥有数千种独特物种,从颜色亮丽的海星、生物发光的蠕虫到淡色章鱼,多种多样。这里还生活着数百万 只企鹅,它们以数量巨大的磷虾为食。磷虾是一种小型的虾状甲壳类动物,与其他觅食物种一起构成了微妙 的食物网的基础。科学家认为,由于受到气候变化的影响,而且该地区的变暖速度快于地球上任何其他地方, 这里的生态系统正在发生改变

在东南极海域中,MacRobertson、Drygalski 和 D’Urville Sea-Mertz 区域就涵盖了将近一百万平方公里。 这三个区域组成了南极海洋生物资源养护委员会 (CCAMLR) 目前正在考虑的海洋保护区系统 (MPA) 提案。 皮尤慈善信托基金会支持成立禁渔海洋保护区,因为证据显示此方法有助于强化生态系统和重建生物多 样性。海洋禁捕区也能提高气候恢复能力。具体而言,禁渔的海洋保护区有助于海洋和地球适应气候变化 的六个主要影响:海洋酸化、海平面上升、风雨强度增强、物种分布改变、生物生产力和含氧量的下降。
