Figure F11. Downhole changes at Site 1144 in (A) the group abundance of siliceous microfossils (including radiolarians, diatoms, and their debris), (B) the proportion of benthic foraminifers (BF) related to high organic carbon flux (high productivity BF), (C) relative abundance of P. obliquiloculata, (D) fragmentation, (E) the ratio between pteropod (PT) and planktonic (PF) foraminifers, and (F) the ratio between G. menardii and G. inflata. Three biostratigraphic events (LO of pink G. ruber, FO of E. huxleyi, and LO of R. asanoi) are shown. The numbers 1, 5, 7, and 9 at the top of the diagram indicate possible marine oxygen isotopic stages. LO = last occurrence, FO = first occurrence. Dotted lines mark the biostratigraphic events of nannofossils; solid bar shows the event of foraminifers.
