Ocean model predictions of chemistry changes from carbon dioxide emissions to the atmosphere and ocean

We present ocean chemistry calculations based on ocean general circulation model simulations of atmospheric CO 2 emission, stabilization of atmospheric CO 2 content, and stabilization of atmospheric CO 2 achieved in total or in part by injection of CO 2 to the deep ocean interior. Our goal is to provide first‐order results from various CO 2 pathways, allowing correspondence with studies of marine biological effects of added CO 2 . Parts of the Southern Ocean become undersaturated with respect to aragonite under the Intergovernmental Panel on Climate Change Special Report on Emissions Scenarios (SRES) A1, A2, B1, and B2 emission pathways and the WRE pathways that stabilize CO 2 at 650 ppm or above.
