TLDR
A solar forcing mechanism therefore may underlie at least the Holocene segment of the North Atlantic's “1500-year” cycle, potentially providing an additional mechanism for amplifying the solar signals and transmitting them globally.Abstract:
Surface winds and surface ocean hydrography in the subpolar North Atlantic appear to have been influenced by variations in solar output through the entire Holocene. The evidence comes from a close correlation between inferred changes in production rates of the cosmogenic nuclides carbon-14 and beryllium-10 and centennial to millennial time scale changes in proxies of drift ice measured in deep-sea sediment cores. A solar forcing mechanism therefore may underlie at least the Holocene segment of the North Atlantic's "1500-year" cycle. The surface hydrographic changes may have affected production of North Atlantic Deep Water, potentially providing an additional mechanism for amplifying the solar signals and transmitting them globally.read more

Periodicity of climate conditions and solar variability derived from dendrochronological and other palaeoclimatic data in high latitudes
TL;DR: The periodicity of climatic processes in the Barents Sea Region and along the Arctic Ocean coast during several hundred years has been studied by analyzing the tree-ring chronologies for the regions close to the northern timberline as discussed by the authors.

Fluviatile palaeoenvironments in archaeological context: Geographical position, methodological approach and global change – Hydrological risk issues
TL;DR: In this paper, three large catchments of Western Europe (Loire, Rhone, Isonzo/Frioul-Italy) have been studied to demonstrate the relevance of combining the three hydrogeomorphological approaches (hydrography, hydrology, hydraulics).

Bacterial magnetite in lake sediments: late glacial to Holocene climate and sedimentary changes in northern Norway
TL;DR: Magnetic properties of sediments retrieved from a small lake in northern Norway spanning the last f14500 cal years have been analyzed in detail as discussed by the authors, with a strong positive statistical relationship (r 2 =083) between the anhysteretic remanent magnetisation susceptibility (vARM) and loss-on-ignition (LOI%) suggests an environmental "control" over the bacteria magnitude.

Late-Holocene Atlantic bottom-water variability in Igaliku Fjord, South Greenland, reconstructed from foraminifera faunas
Susanne Juul Lassen,Antoon Kuijpers,Helmar Kunzendorf,Gerd Hoffmann-Wieck,Naja Mikkelsen,Peter Konradi +5 more
TL;DR: In this paper, a high-resolution record of late-Holocene subsurface water-mass characteristics in outer Igaliku Fjord, South Greenland, is presented based on benthic foraminifera faunas from core PO 243-451 collected from a water depth of 304 m.

A Pervasive Millennial-Scale Cycle in North Atlantic Holocene and Glacial Climates

TL;DR: In this paper, the North Atlantic deep sea cores reveal that abrupt shifts punctuated what is conventionally thought to have been a relatively stable Holocene climate, and they make up a series of climate shifts with a cyclicity close to 1470 ± 500 years, which is the most recent manifestation of a pervasive millennial-scale climate cycle operating independently of the glacial-interglacial climate state.

Revised carbonate-water isotopic temperature scale
TL;DR: The relationship between temperature and O(18) content relative to that for a Cretaceous belemnite of the Pee Dee formation previously reported (Epstein, Buchsbaum, Lowenstam, and Urey, 1951) has been re-determined using modified procedures for removing organic matter from shells, and is found to be 16.5 - 4.3 δ + 0.14 δ^2
