North Atlantic sediments dating from the last ice age contain layers of rock fragments from northeastern Canada (so-called Heinrich layers). Like modern iceberg-borne sediments from Greenland, these layers have been attributed to ice-rafting episodes. Six Heinrich layers have been documented and correlated with climate changes. The layers, which are several centimetres thick, contain negligible amounts of foraminifera (which accumulate at a few millimetres per century), implying that they were… Expand
Massive late Pleistocene detritus layers of the North Atlantic and their global climate imprint
[1] Millennial climate oscillations of the glacial interval are interrupted by extreme events, the so-called Heinrich events of the North Atlantic. Their near-global footprint is a testament toExpand
Glacial geomorphology in Utsjoki, Finnish Lapland proposes Younger Dryas fault-instability.
Abstract Northern Fennoscandia has experienced high-magnitude postglacial fault (PGF) events, yet the role of seismic tremors in subglacial deformations and meltwater discharge has remained obscure.Expand
Source, timing, frequency and flux of ice‐rafted detritus to the Northeast Atlantic margin, 30–12 ka: testing the Heinrich precursor hypothesis
Increased fluxes of ice-rafted detritus (IRD) from European ice sheets have been documented some 1000–1500 years before the arrival of Laurentide Ice Sheet (LIS)-sourced IRD during Heinrich (H)Expand

SEDIMENTS in the North Atlantic ocean contain a series of layers that are rich in ice-rafted debris and unusually poor in foraminifera1. Here we present evidence that the most recent six of theseExpand

TLDR
Oscillations of Pinus (pine) pollen in a 50,000-year sequence from Lake Tulane, Florida, indicate that there were major vegetation shifts during the last glacial cycle and seems to be temporally correlated with the North Atlantic Heinrich events. Expand

Interhemispheric Correlation of Late Pleistocene Glacial Events
TLDR
The last termination began suddenly and simultaneously in both polar hemispheres before the resumption of the modern mode of deep-water production in the Nordic Seas and interhemispheric coupling implies a global atmospheric signal rather than regional climatic changes caused by North Atlantic thermohaline switches or Laurentide ice surges.
