Figure F21. Comparison of color reflectance b* and planktonic foraminiferal distribution data, Hole U1427A. The percentage of planktonics refers to the total foraminiferal assemblage. The percentage of various species is expressed as a percentage of the total planktonic assemblage. Red arrows = G. ruber, purple arrows = P. obliquiloculata. Black down and up arrows indicate LO and FO, respectively, of each species. Barren = sample intervals barren of calcareous microfossils, rare = intervals where calcareous microfossils are present in very low numbers.
