Over the last million years, ice ages have intensified and lengthened. According to a new study co-authored by AOS Postdoctoral Research Fellow Alex Haumann, this previously unexplained climate transition coincides with a diminution of the mixing between deep and surface waters in the Southern Ocean. The study, published in Science today, confirms that the Antarctic region plays a crucial role during periods of climate change. Danny Sigman, Princeton's Dusenbury Professor of Geological and Geophysical Sciences, is among the paper's co-authors.
