Carbon From Southern Ocean Tied to Last Deglaciation (2 of 4) (IMAGE)
Caption
The carbonate skeletons of fossil deep-sea corals can be used to reconstruct past changes in the ocean. This specimen of Desmophyllum dianthus was collected from the Drake Passage in the Southern Ocean on cruise NBP08-05. When these corals die, their skeletons can provide a record of the chemistry of the seawater in which they grew. This image relates to a paper that appeared in the Dec. 15, 2011, issue of Science Express, published by AAAS. The paper, by A. Burke at the MIT/WHOI Joint Program in Oceanography in Woods Hole, Ma., and colleagues, was titled, “The Southern Ocean’s Role in Carbon Exchange During the Last Deglaciation.”
