Reformation of the surface oceanic circulation during Paleogene: Calcareous nannoplanktonic, foraminiferal and oxygen isotopic evidences

ABSTRACT: Paleogene calcareous nannoplankton evolution with regard to morphotype changes was analysed. The^°0/1"0 ratio in planktonic foraminifera tests was studied. Conclusions about surface water temperature and salinity changes and about main features of surface circulation based on these da...
