Ocean acidification and the Southern Ocean


"Scientists at the Australian Antarctic Division and the Antarctic Climate and Ecosystems Cooperative Research Centre,based in Hobart, are conducting a range of experiments on plankton andsediments from the Southern Ocean, to determine the effect ofincreasing CO2 on marine organisms and the impacts this will have on the ecosystem. A research voyages in 2007, the Sub-Antarctic Zone Sensitivity to Environmental Change conducted ship-board experiments and brought back samples for laboratory analysis.

Why is Southern Ocean research so important?

The Southern Ocean contains more CO2 than other oceans because cooler water absorbs more CO2 than warmer water. Thus, the impacts of ocean acidification will appear first in the Southern Ocean."


The Antarctic Climate and Ecosystems Cooperative Research Centre (ACECRC) provides a focus for Australia’s national effort to understand thevariability of Antarctica and the Southern Ocean and their role inAustralia’s future. The ACE CRC is a partnership dedicated tosustainable management of Antarctic marine ecosystem resources and thestudy of atmospheric and oceanic processes of the Southern Ocean andtheir role in global and regional climate change.
