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

Decadal to millennial-scale periodicities in North Iceland shelf sediments over the last 12 000 cal yr: long-term North Atlantic oceanographic variability and solar forcing
John T. Andrews,Jorunn Hardadottir,Joseph S Stoner,Michael E. Mann,Greta B Kristjánsdóttir,Nalan Koc +5 more
TL;DR: In this article, the authors investigated the relationship between the sediment magnetic properties and the D 18 O on benthic foraminifera on the North Iceland inner shelf and found that the links between variations in grain-size, magnetic concentrations, and solar forcing are controlled by atmospheric and oceanographic changes linked to changes in the relative advection of Atlantic and polar waters along the North Icelandic margin.

Holocene palaeohydrology and climate variability in northeastern Spain: The sedimentary record of Lake Estanya (Pre-Pyrenean range)
Mario Morellón,Blas L. Valero-Garcés,Ana Moreno,Ana Moreno,Penélope González-Sampériz,Pilar Mata,Oscar E Romero,Melchor Maestro,Ana Navas +8 more
TL;DR: In this paper, a multi-proxy study of sediment cores from karstic Lake Estanya (Pre-Pyrenean Range, NE Spain) provides the first complete, continuous record of the hydrological evolution in the northeastern Iberian Peninsula over the last 9500-yr.

High-resolution alkenone sea surface temperature variability on the North Icelandic Shelf: implications for Nordic Seas palaeoclimatic development during the Holocene
TL;DR: In this paper, the authors reconstructed the palaeoceanography of the northern Icelandic Shelf for the Holocene period from alkenone indices measured in core JR51-GC35, which contains a continuous record of Holocene sedimentation spanning 0.2 cal. kyr BP with a resolution of � /20 yr/cm.

Millennial to multi-decadal variability in the climate of southern Africa
TL;DR: In this article, the structure of the variability in a 3000-year δ18O record has been compared with that in tree ring data for the last 600 years and both to variability in annual rainfall and runoff during the 20th century.

Bunker Cave stalagmites: an archive for central European Holocene climate variability

TL;DR: In this article, the authors present a new record of past winter climate variability for the last 10.8 ka based on four speleothems from Bunker Cave, Western Germany, which is particularly well suited to record changes in precipitation and temperature in response to changes in the North Atlantic realm.

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
