Ocean Carbon Storage

How the oceans store CO 2 is critical for understanding the global carbon cycle CO 2 uptake is not the same as carbon storage Anthropogenic CO 2 absorbed in one region may be moved by ocean circulation and ultimately stored in a different region Map of the column inventory of anthropogenic CO2 in 1994 (Sabine et al, 2004)To try to understand the ocean’s carbon limits, Feely and the rest of the oceanography community measure dissolved carbon and the ocean’s pH They probe its temperature, alkalinity, salinity, and record the presence of tracers like chlorofluorocarbons or helium to find out when the water was last exposed to the atmosphere By the end of a typical cruise, they will haveThe Ocean’s Carbon Balance NASA Earth Observatory

6 Could CO2 be stored in the deep ocean?

Oceans cover over 70% of the earth’s surface and their average depth is 3,800 m Because carbon dioxide is soluble in Costs of ocean storage Although there is no experience with ocean storage, some attempts have been made to estimate the costs of CO 2 storage projects that release CO 2 on the sea floor or in the deep ocean The costs of CO 2 capture andTwo sequestration strategies are under intense study at the Department of Energy's Center for Research on Ocean Carbon Sequestration (DOCS), where Jim Bishop of Berkeley Lab's Earth Sciences Division is codirector with Livermore Lab's Ken Caldeira One is direct injection, which would pump liquefied carbon dioxide a thousand meters deep or deeper, either directly fromCarbon Sequestration in the Ocean
