Geochemistry of karst deposits in Borneo detailing hydroclimate variations in the Warm Pool across the late Pleistocene
… defined in the North Atlantic sediment records (“Heinrich events”). The inferred drying (increased stalagmite δ18O) during Heinrich events is consistent with a southward shift of the Intertropical Convergence Zone – the dominant paradigm to explain global climate anomalies originating in the north …

Geochemical tracers in the deep-sea and the North Sea
… input of loess material during the last Heinrich-events. In the Arabian Sea, the climatic influence on the scavenging intensity of 230 Th xs could be demonstrated over the last 100 ka. During cold periods, a high input of the Indus river occurs, while in warm periods biogenic particle …

Speleothem climate capture of the Neanderthal demise
… (δ18O, δ13C, Mg and Sr). Millennial-scale events coincident with the timing of North Atlantic Heinrich Events have been identified and the sub-orbital climate variability resembles that of North Atlantic Dansgaard-Oeschger cycles. Therefore, evidence from the speleothems demonstrates a …

Questions and clarity: insights from applying computational methods to paleoclimate archives
… Lake. Next, the tracks of icebergs purged during Heinrich Events are simulated using the MIT General Circulation Model. This work, running multiple experiments exploring different aspects internal and external to the icebergs, reveals wind and sediment partitioning as centrally important to the …

Reconstructing Surface Water Carbonate Ion Concentration Changes in the Eastern Equatorial Pacific Across Glacial Transitions
… coupled with dust fertilization across cold Heinrich events failed to stimulate biological productivity to the point where the region switched to being a sink for atmospheric CO<sub>2</sub>. Sustained lower-than-modern surface water [CO<sub>3</sub><sup>2-</sup>] across both climate …

Tidally Forced Marine Ice Stream Instabilities and Their Consequences
… and an explanation for all major climatic events of the last 20,000 years in which the resumption of the AMOC after Heinrich event 1 leads to the B{\o}lling-Aller{\o}d warming, which results in increased melt of the Laurentide and provides the source of MWP1A. Similarly, the recovery of the …

Paleoenvironmental changes in the Black Sea region during the last 26,000 years : a multi-proxy study of lacustrine sediments from the western Black Sea
… the cooling associated with the North Atlantic Heinrich Events H1 and H2. In contrast to regional precipitation changes, the hydrological properties of the Black Sea remained relatively stable under full glacial conditions. First significant modification in the freshwater/sediment sources …
