Holocene periodicity in North Atlantic climate and deep-ocean flow south of Iceland

  title={Holocene periodicity in North Atlantic climate and deep-ocean flow south of Iceland},
  author={G. G. Bianchi and I. McCave},
Climate fluctuations during the past millennium are relatively well documented. On a longer timescale, there is growing evidence of millennial-scale variability of Holocene climate, at periodicities of ∼2,500 and 950 years (possibly caused by changes in solar flux), and ∼1,500 years (maybe related to an internal oscillation of the climate system),,. But the involvement of deep water masses in these Holocene climate changes has yet to be established. Here we use sediment grain-size data from the… Expand

Holocene climate variability in the northern North Atlantic region: A review of terrestrial and marine evidence.
The Holocene epoch, which followed the last major pulse of glaciation (the Younger Dryas) at the end of the last glaciation, encompasses a period before there was any substantial anthropogenicExpand
Mechanisms for climate variability during glacial and interglacial periods
[1] This paper suggests and explores mechanisms relevant to millennial-scale climate variability during glacial periods. In particular, we present the results of model studies that are able toExpand
Marine records of Holocene climatic variations
Abstract Holocene millennial climate variability is smaller than that of the last glaciation, due to the disappearance of large unstable ice sheets. Marine records show that the sea-surfaceExpand
Holocene oscillations in temperature and salinity of the surface subpolar North Atlantic
The temperature and salinity changes of a substantial surface inflow to a region of deep-water formation throughout the Holocene are investigated and suggest that such a negative feedback mechanism may have operated during past intervals of climate change. Expand
Holocene Climate Variability on Centennial-to-Millennial Time Scales: 1. Climate Records from the North-Atlantic Realm
Holocene oxygen isotope data from the GISP2 ice core reveal temperature oscillations in Greenland with a periodicity of ~900 y, which can be correlated to climate perturbations in northern andExpand
North Atlantic forcing of moisture delivery to Europe throughout the Holocene
This is the first continental record of its type that clearly demonstrates millennial scale connectivity between the pulse of the ocean and precipitation over Europe through the entirety of the Holocene. Expand
Testing solar forcing of pervasive Holocene climate cycles
The temporal and spatial extent of Holocene climate change is an area of considerable uncertainty, with solar forcing recently proposed to be the origin of cycles identified in the North AtlanticExpand

Abrupt climate change and glacial terminations
The Earth’s system has witnessed abrupt climate changes throughout its history. It is widely understood that the pacing of the large-scale glacial-interglacial cycles (tens to hundreds of thousandsExpand
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


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
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
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
Circulation in the glacial North Atlantic inferred from grain-size measurements
RECORDS of nutrient proxies in marine sediments indicate that the nutrient distribution—and hence circulation—of the glacial North Atlantic Ocean was markedly different from that of today1,2. ButExpand

Abrupt climate events 500,000 to 340,000 years ago: evidence from subpolar north atlantic sediments
Subpolar North Atlantic proxy records document millennial-scale climate variations that have an approximately constant pacing that is similar to that documented for the last glacial cycle, suggesting that such climate variations are inherent to the late Pleistocene, regardless of glacial state.
