| Abstract: | 14C specific activities in the western Atlantic show aging of about 160 years between 42°N and 30°S for southward-moving North Atlantic Deep Water. Most of the aging occurs in the North Atlantic, with a small increase in14C level for abyssal water near the equator.The northward-flowing Antarctic Bottom Water component ages about 80 years between 50°S and the equator. The rate of Atlantic bottom water formation is estimated at 18 Sverdrups; the rate of flow for northward-moving Antarctic Bottom Water at about 6 Sverdrups. |
