Nearsurface 4C values for the eastern portion of both the northern and southern subtropical gyres decreased by 25-50\%, with the change being greater in the north. Equatorial near-surface values have increased by ca. 25\%. Changes in the 250-750-m depth range are dramatically different between the northern and southern basins. The intermediate and mode waters of the southern basin have increased by as much as 75\%o since GEOSECS. Waters of similar density in the northern hemisphere are not exposed to the Southern Ocean circulation regime and are significantly less ventilated, showing maximum changes of ca. 50\%. }, url = {https://journals.uair.arizona.edu/index.php/radiocarbon/article/view/1918}, author = {Key, R.
