Figure F5. A. The record of weight percent sand experiences a strong decrease matching the increase in carbonate content from 273 to 272.8 mbsf (279.68-279.48 mcd). A second increase in carbonate content occurs at 252.06-250.86 mbsf. B. Increases in benthic and bulk ¹³C occur over a number of samples from 269.36 to 269.16 and 269.16 to 268.56 mbsf. C. The strong increase in benthic ¹⁸O at 258.65 mbsf is identified as the onset of the Mi-1 event.
