Abstract

Deep-sea drilling in the Southern Ocean south of Australia and New Zealand shows that the Circum-Antarctic Current developed about 30 million years ago in the middle to late Oligocene when final separation occurred between Antarctica and the continental South Tasman Rise. Australia had commenced drifting northward from Antarctica 20 million years before this.

摘要

澳大利亚和新西兰南部南大洋的深海钻探表明，大约在 3000 万年前的中晚期渐新世，当南极洲和大陆的南塔斯曼隆起最终分离时，环南极海流开始发展。在此之前的 2000 万年前，澳大利亚已开始从南极洲向北漂移。
