Journal ArticleDOI
Complexity of Holocene Climate as Reconstructed from a Greenland Ice Core
S. R. O'Brien,Paul Andrew Mayewski,L. D. Meeker,D. A. Meese,Mark S. Twickler,Sallie I. Whitlow +5 more
TL;DR: In this paper, the chemical composition of the atmosphere was dynamic during the Holocene epoch and concentrations of sea salt and terrestrial dusts increased in Summit snow during the periods 0 to 600, 2400 to 3100, 5000 to 6100, 7800 to 8800, and more than 11,300 years ago.
Journal ArticleDOI
Major features and forcing of high-latitude northern hemisphere atmospheric circulation using a 110,000-year-long glaciochemical series
Paul Andrew Mayewski,L. D. Meeker,Mark S. Twickler,Sallie I. Whitlow,Qinzhao Yang,W. Berry Lyons,Michael L. Prentice +6 more
TL;DR: The Greenland Ice Sheet Project 2 glaciochemical series (sodium, potassium, ammonium, calcium, magnesium, sulfate, nitrate, and chloride) provides a unique view of the chemistry of the atmosphere and the history of atmospheric circulation over both the high latitudes and mid-low latitudes of the northern hemisphere as discussed by the authors.
Journal ArticleDOI
Record of Volcanism Since 7000 B.C. from the GISP2 Greenland Ice Core and Implications for the Volcano-Climate System.
Gregory A. Zielinski,Paul Andrew Mayewski,L. D. Meeker,Sallie I. Whitlow,Mark S. Twickler,Michael C. Morrison,D. A. Meese,Anthony J. Gow,Richard B. Alley +8 more
TL;DR: Sulfate concentrations from continuous biyearly sampling of the GISP2 Greenland ice core provide a record of potential climate-forcing volcanism since 7000 B.C. with sulfate deposition equal to or up to five times that of the largest known historical eruptions.
Journal ArticleDOI
Changes in Atmospheric Circulation and Ocean Ice Cover over the North Atlantic During the Last 41,000 Years
Paul Andrew Mayewski,L. D. Meeker,Sallie I. Whitlow,Mark S. Twickler,Michael C. Morrison,Peter Bloomfield,Gerard C. Bond,Richard B. Alley,Anthony J. Gow,D. A. Meese,Pieter Meiert Grootes,Michael Ram,Kendrick C. Taylor,W. Wumkes +13 more
TL;DR: High-resolution, continuous multivariate chemical records from a central Greenland ice core provide a sensitive measure of climate change and chemical composition of the atmosphere over the last 41,000 years.
Journal ArticleDOI

TL;DR: A north-to-south directionality of the abrupt climatic signal is demonstrated, which is propagated to the Southern Hemisphere high latitudes by oceanic rather than atmospheric processes, which confirms a central role for ocean circulation in the bipolar seesaw.
