Calcareous microfossil isotopes and Miocene datum events of ODP Holes 189-1170A and 189-1172A
Downcore oxygen and carbon stable isotope records of planktonic and benthic foraminifers and fine-fraction carbonate from the southern high latitudes provide critical paleohydrographic constraints on the evolution of the Southern Ocean climate. In particular, the potential effects of an intensified...
