TL;DR: In this article, the authors present evidence that the most recent six Heinrich layers, deposited between 14,000 and 70,000 years ago, record marked decreases in sea surface temperature and salinity, decreases in the flux of planktonic foraminifera to the sediments, and short-lived, massive discharges of icebergs originating in eastern Canada.

TL;DR: In this paper, the authors present detailed information documenting the existence of the upper five of these layers in ODP core 609 from 50° N and 24° W. Their ages are respectively 15 000 radiocarbon years, 20, 000, 27, 000 and 50, 000 years.

TL;DR: In this paper, it was shown that for water depths of more than 4 km in the tropical Pacific, the radiocarbon age increases with the extent of dissolution, and that this increase must be the result of chemical erosion.

TL;DR: In this paper, accelerator radiocarbon measurements on hand picked benthic and planktonic foraminifera separated from two deep sea cores raised from the South China Sea were used to place limits on the extent to which the ventilation rate of the deep Pacific Ocean has changed over the last 12000 years.

TL;DR: In this article, the authors discuss the possible causes for these differences and attempt to evaluate their impact on the interpretation of benthic-planktonic age differences and evaluate the impact of these differences on the ventilation rate of planktonic foraminifera.
