We reconstructed the ventilation record of deep water at 2100 m depth 27" Self Clean Wall Oven in the mid-latitude western North Pacific over the past 25 kyr from radiocarbon measurements of coexisting planktic and benthic foraminiferal shells in sediment with a high sedimentation rate.The ¹⁴C data on fragile and robust planktic foraminiferal shells were concordant with each other, ensuring high quality of the reconstructed ventilation record.The radiocarbon activity changes were consistent with the atmospheric record, suggesting that no massive Abstract Wall Art mixing of old carbon from the abyssal reservoir occurred throughout the glacial to deglacial periods.
