Research project: North vs South? What’s filling the Atlantic?
CO2 varies strongly on glacial-interglacial timescales, this is known from bubbles trapped in ice cores and ice deposited sediments. The control of this change over the last 3 million years when the Northern Hemisphere has been glaciated remains largely unknown despite many years of research. New modeling studies show the volume of water of southern origin in the Atlantic may play a role in declining pCO2. With carbon dioxide levels presently rising in the atmosphere, the oceans capacity to resist/effect change is crucial to our understanding of global climate change and ocean acidification.
