DSDP North Atlantic Site 608 yielded an excellent Miocene pelagic section which affords a further opportunity for elucidating the chronology of the calcareous nannofossil...

Calcareous nannoplankton biostratigraphy has been worked out in the eastern Mediterranean utilizing deep-sea sediments recovered from DSDP Leg 42A Sites 375 and 376. These two...

Only Site 802 has recorded appreciable Cenozoic carbonate sediments during Ocean Drilling Program Leg 129 in the central Mariana Basin of the western Pacific Ocean. Calcareous...

Calcareous nannoplankton from 44 samples of a thick (169.5 m) Neogene section of DSDP Site 516 in the South Atlantic was studied. More than 60 species were determined....
