CO2 Transport in Deep Waters Off Wilkes Land
The densest waters in the world ocean are formed on the continental shelf areas around Antarctica by ice formation and by the loss of heat and water to the air. The Weddell Sea (e.g., Gordon, 1971; Carmack and Foster, 1975; Foldvik et al., 1985), the Ross Sea (e.g., Jacobs et al., 1970, 1985) and ot...
