Oxygen dip in southern ocean



Climate simulations predict a decrease in oxygen at depths of 500–2,500 meters in the southern ocean around Antarctica, a team of Australian climate researchers announced on 15 March.

“The interpretation [from the simulations[ is that less oxygen-rich water is penetrating into the ocean, and this in turn gives additional credibility to climate change models. The oxygen analysis provides a new benchmark of understanding for researchers, “said Richard Matear, an oceanographer with Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO).
