(Figure 6) Distribution of middle Miocene to late Pliocene calcareous nannofossils in ODP Hole 132-810C

Sediment depth is given in mbsf. Species abundance: A = abundant (more than 1 specimen per field of view; 1250 X); C = common (at least 1 specimen in 10 fields of view); F = frequent (at least 1 specimen in 30 fields of view); R = rare (less than 1 specimen in 30 fields of view); RR = very rare (1 or 2 specimens detected during the analysis).
