Seafloor topography drives Earth's great conveyor belt
In the Southern Ocean, the world’s largest current in terms of volume transport — the Antarctic Circumpolar Current (ACC) — encircles Antarctica and connects the Atlantic, Indian and Pacific ocean basins, as it flows from west to east. The ACC influences ocean circulation and global climate, as it rises from the deep to interact with the atmosphere. In a new study, published in the Journal of Geophysical Research: Oceans, researchers have directly measured how seafloor topography affects the current’s structure — something that had only been theorized previously.

Did you know ...
EARTH only uses professional science journalists and scientists to author our content? In this era of fake news and click-bait, EARTH offers factual and researched journalism. But EARTH is a non-profit magazine, and at least 10 times more people read EARTH than pay for it. As advertising revenues across the media decline, we need your help to ensure that we can continue bringing you the reliable and well-written coverage of earth science you know and love. Our goal is not only to inform our readers, but to inform decision makers across the economic and political spectrum about the science of our planet. So, we need your help. By becoming a subscriber or making a tax-deductible contribution to support EARTH, you can fund our writers and help make sure the world knows about our planet.
