Glacial to deglacial reservoir ages of surface waters in the southern South Pacific ...
Ocean sediment records document abrupt changes in glacial-to-deglacial circulation and mixing of the ocean, recorded as changes in 14C reservoir ages of surface waters. Here we present 14C-based high-resolution age records of four sediment cores from the western and eastern continental margins of th...
