Evidence from a North Atlantic deep-sea sediment core reveals that the largest climatic perturbation in our present interglacial, the 8200-year event, is marked by two distinct cooling events in the subpolar North Atlantic at 8490 and 8290 years ago. An associated reduction in deep flow speed provides evidence of a significant change to a major downwelling limb of the Atlantic meridional overturning circulation. The existence of a distinct surface freshening signal during these events strongly… Expand

Reduced North Atlantic Deep Water Coeval with the Glacial Lake Agassiz Freshwater Outburst
New stable isotopic and sedimentological records from a northwest Atlantic sediment core reveal that the most prominent Holocene anomaly in bottom-water chemistry and flow speed in the deep limb of the Atlantic overturning circulation begins at ∼8.38 thousand years B.P, confirming the ocean's sensitivity to freshwater forcing.

North Atlantic climate and deep‐ocean flow speed changes during the last 230 years
Variations in the near-bottom flow speed of Iceland-Scotland Overflow Water (ISOW) are documented in a 230-year-long deep-sea sediment record from the eastern flank of Reykjanes Ridge in the subpolarExpand
Dynamics of North Atlantic Deep Water masses during the Holocene
High resolution flow speed reconstructions of two core sites located on Gardar Drift in the northeast Atlantic Basin and Orphan Knoll in the northwest Atlantic Basin reveal a long-term decrease inExpand
South Atlantic island record reveals a South Atlantic response to the 8.2 kyr event
Abstract. One of the most distinct climate fluctuations during the Holocene is the short and rapid event centred around 8200 years ago, the 8.2 kyr event, which was most likely triggered by glacialExpand
Terrestrial climate signal of the "8200 yr B.P. cold event" in the Labrador Sea region
Accelerated melting of Greenland ice has raised concern about the future impact of enhanced freshwater discharge on regional climate through its effect on ocean circulation. An abrupt cooling eventExpand
Trends and centennial-scale variability of surface water temperatures in the North Atlantic during the Holocene
Abstract Two sediment cores retrieved off North Iceland (western Nordic Seas) and on the eastern flank of Reykjanes Ridge (Iceland Basin) were analyzed to generate high-resolution alkenone-derivedExpand
Episodic reductions in bottom-water currents since the last ice age
Although North Atlantic deep-water formation was greatly reduced during the last glacial maximum, bottom-water currents were as vigorous as at present. However, they were weakened during periods ofExpand
North Atlantic Deep Water and climate variability during the Younger Dryas cold period
The Younger Dryas, the last large millennial-scale climate oscillation (12.9–11.6 ka), has been widely attributed to a massive meltwater discharge event that disrupted ocean circulation and plungedExpand
A 4500-year reconstruction of sea surface temperature variability at decadal time-scales off North Iceland
Marine paleo-records acquired at high temporal resolution provide critical data for testing numerical climate models and help to understand processes underlying ocean variability. This study presentsExpand
The 8.2 ka event: Abrupt transition of the subpolar gyre toward a modern North Atlantic circulation
[1] Climate model simulations of the 8.2 ka event show an abrupt strengthening of the Atlantic subpolar gyre that allows us to connect two major but apparently contradictory climate events of theExpand


Freshwater Forcing of Abrupt Climate Change During the Last Glaciation
It is found that periods of increased freshwater flow to the North Atlantic occurred at the same time as reductions in the formation of North Atlantic Deep Water, thus providing a mechanism for observed climate variability that may be generally characteristic of times of intermediate global ice volume.

Holocene climatic instability: A prominent, widespread event 8200 yr ago
The most prominent Holocene climatic event in Greenland ice-core proxies, with approximately half the amplitude of the Younger Dryas, occurred ∼8000 to 8400 yr ago. This Holocene event affectedExpand
A Pervasive Millennial-Scale Cycle in North Atlantic Holocene and Glacial Climates
Evidence from North Atlantic deep sea cores reveals that abrupt shifts punctuated what is conventionally thought to have been a relatively stable Holocene climate. During each of these episodes,Expand
Ocean circulation and climate during the past 120,000 years
Evidence implicates ocean circulation in abrupt and dramatic climate shifts, such as sudden temperature changes in Greenland on the order of 5–10 °C and massive surges of icebergs into the North Atlantic Ocean. Expand
Complexity of Holocene Climate as Reconstructed from a Greenland Ice Core
Glaciochemical time series developed from Summit, Greenland, indicate that the chemical composition of the atmosphere was dynamic during the Holocene epoch. Concentrations of sea salt and terrestrialExpand
Centennial-scale climate cooling with a sudden cold event around 8,200 years ago
The compounded nature of the signals implies that far-field climate anomalies around 8,200 years ago cannot be used in a straightforward manner to assess the impact of a slowdown of North Atlantic Deep Water formation, and the geographical extent of the rapid cooling event 8, 200  years ago remains to be determined.

Centennial to millennial scale Holocene climate-deep water linkage in the North Atlantic
The stability of the Earth's climate is strongly linked to the steadiness of the atmospheric and oceanic transport of heat from low to high latitudes. High resolution Holocene sedimentary recordsExpand

Collapse and rapid resumption of Atlantic meridional circulation linked to deglacial climate changes
It is found that the meridional overturning was nearly, or completely, eliminated during the coldest deglacial interval in the North Atlantic region, beginning with the catastrophic iceberg discharge Heinrich event H1, 17,500’yr ago, and declined sharply but briefly into the Younger Dryas cold event, about 12,700 yr ago.
