a C37:4% in IODP U1385. The high C37:4% period is highlighted by green dashing. b The percentage of reworked coccolith/nannofossils. c The abundance of fossils. d The oxygen isotope difference between planktonic foraminifera and fine fraction. The dashed line represents the mean value for all measurements. e Alkenone flux (orange) and alkenone content (blue). Note the axis of alkenone flux is in log10 scale.
