A Pervasive Millennial-Scale Cycle in North Atlantic Holocene and Glacial Climates
Gerard C. Bond,William J. Showers,Maziet Cheseby,Rusty Lotti,Peter Almasi,Peter B deMenocal,Paul Priore,Heidi Cullen,Irka Hajdas,Georges Bonani +9 more
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.
Journal ArticleDOI
Persistent Solar Influence on North Atlantic Climate During the Holocene
Gerard C. Bond,Bernd Kromer,Juerg Beer,Raimund Muscheler,Michael N. Evans,William J. Showers,Sharon Hoffmann,Rusty Lotti-Bond,Irka Hajdas,Georges Bonani +9 more
TL;DR: 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.
Journal ArticleDOI
Correlations between climate records from North Atlantic sediments and Greenland ice
Gerard C. Bond,Wallace S. Broecker,Sigfus J Johnsen,Sigfus J Johnsen,Jerry F. McManus,Laurent Labeyrie,Jean Jouzel,Jean Jouzel,Georges Bonani +8 more
TL;DR: In this article, the authors present records of sea surface temperature from North Atlantic sediments spanning the past 90 kyr which contain a series of rapid temperature oscillations closely matching those in the ice-core record, confirming predictions that the ocean must bear the imprint of the Dansgaard-Oeschger events.
Journal ArticleDOI
Evidence for massive discharges of icebergs into the North Atlantic ocean during the last glacial period
Gerard C. Bond,Hartmut Heinrich,Wallace S. Broecker,Laurent Labeyrie,Jerry F. McManus,John T. Andrews,Sylvain Huon,Ruediger Jantschik,Silke Clasen,Christine Simet,Kathy Tedesco,Mieczyslawa Klas,Georges Bonani,Susan Ivy +13 more
TL;DR: In this article, the authors present evidence that the most recent six Heinrich layers, deposited between 14,000 and 70,000 years ago, record marked decreases in sea surface temperature and salinity, decreases in the flux of planktonic foraminifera to the sediments, and short-lived, massive discharges of icebergs originating in eastern Canada.
Journal ArticleDOI
Routing of meltwater from the Laurentide Ice Sheet during the Younger Dryas cold episode
Wallace S. Broecker,James P. Kennett,Benjamin P. Flower,James T. Teller,Susan E. Trumbore,Georges Bonani,Willy Wolfli +6 more
TL;DR: In this article, the authors present oxygen isotope and accelerator radiocarbon measurements on planktonic foraminifera from Orca Basin core EN32-PC4 which reveal a significant reduction in meltwater flow through the Mississippi River to the Gulf of Mexico from about 11,200 to 10,000 years ago.
