During ODP Leg 177, a Miocene to Pliocene calcareous nannofossil record was recovered at Sites 1088 and 1090. Site 1088, located at 41 degrees 8'S, shows a continuous middle-upper Miocene to Pliocene carbonate sequence that was deposited at relatively high sedimentation rates. Moreover, Site 1088 proved suitable for calcareous nannofossil analysis as a means to improve the biostratigraphy at this southern latitude. Site 1090 was drilled at 42 degrees 54'S; a tephra layer marks a significant disconformity at the Miocene/Pliocene boundary of this sequence Although nannofossil assemblages are poorly preserved at this site they may help in determining the age of the disconformity and its paleoceanographic significance.
