Calcareous nannofossil abundances in ODP Hole 143-865C


Preservation: P = poor (specimens severly etched/overgrown, primary features destroyed, fragmented, hard to ID to species and/or genus level) and M = moderate (specimens exhibit some etching/recrystallization but identifiable to species level) Total calcareous nannofossil abundance in the sediment: A = abundant (>50-90% of sediment particles)Abundance of individual calcareous nannofossil taxa used in this study: R= rare (1-10 specimens per FOV); A = abundant (>10-100 specimens per FOV and D = dominant (>100 specimens per FOV). For study specific abundance definitions from previously published work see Bralower and Mutterlose (1995). For samples in this study, blank cells indicate that the species was not observed. For selected biostratigraphically important taxa (in bold) a dash is used to indicate where the sample has been inspected in this study or Bralower and Mutterlose (1995) but the species not found. Only abundance data for selected biostratigraphically important taxa have been transcribed here from Bralower and Mutterlose (1995). Datum picks used here are shown in highlighted grey cells. Dictyo. = Dictyococcites; Cr. = Cribrocentrum; Reticulofenestra (Dictyo.) stavensis = R. (Dictyo.) scrippsae in main text
