Figure F4. A. The record of weight percent sand (>63 µm) indicates two important changes between 476.66 and 473.61 mbsf (no samples) and 406.69 and 405.34 mbsf, while the carbonate content increases across the core gap from 377.46 to 376.50 mbsf. B. Increases in benthic and bulk ¹³C occur over a number of samples from ~401 to 398 mbsf, while a decrease in benthic ¹³C from 375.56 to 375.06 mbsf appears more gradual.
