A front page article and supplemental material were published by the American Geophysical Union in the Nov. 15, 2011 issue of EOS on "Ocean Deoxygenation, Past, Present, and Future." The article was the product of an NAI-sponsored workshop held at NASA's Ames Research Center in early 2010. The workshop brought together experts in modern and ancient ocean science to identify and develop synergies between studies of global climate change in the distant past and the present. The full workshop report is also available.
