TL;DR: An undisturbed climate record from a North Greenland ice core, which extends back to 123,000 years before the present, within the last interglacial period, shows a slow decline in temperatures that marked the initiation of the last glacial period.
Journal ArticleDOI
Dating of Greenland ice cores by flow models, isotopes, volcanic debris, and continental dust
Claus U. Hammer,H. B. Clausen,Willi Dansgaard,Niels S. Gundestrup,Sigfus J Johnsen,Niels Reeh +5 more
TL;DR: The available methods for dating of ice cores are based on radioactive decay, ice-flow calculations, or stratigraphic observations as discussed by the authors, and special emphasis is given to stratigraphy methods.
Journal ArticleDOI
The climate signal in the stable isotopes of snow from Summit, Greenland: Results of comparisons with modern climate observations
James W. C. White,L. K. Barlow,David A. Fisher,Pieter Meiert Grootes,Jean Jouzel,Sigfus J Johnsen,Minze Stuiver,H. B. Clausen +7 more
TL;DR: In this paper, the isotope composition of snow in Greenland with meteorological and climatic parameters has been linked with the past few hundred years measured in ice cores using a new record of isotope values from the Greenland Ice Sheet Project 2 and Greenland Ice Core Project sites at Summit, Greenland.
Journal ArticleDOI
Primary aerosol (sea salt and soil dust) deposited in Greenland ice during the last climatic cycle: Comparison with east Antarctic records
TL;DR: In this paper, a detailed comparison between Greenland (Dome Summit) and Antarctic (Vostok) records provides new insight on a potential link between northern and southern patterns, and the sensitivity of Greenland and Antarctic marine input to climate variations of small and large amplitude is compared, and a corresponding estimation is made for the aeolian contribution.
Journal ArticleDOI
Sulfur‐containing species (methanesulfonate and SO4) over the last climatic cycle in the Greenland Ice Core Project (central Greenland) ice core
Michel Legrand,Claus U. Hammer,M. de Angelis,Joel Savarino,Robert J. Delmas,H. B. Clausen,Sigfus J Johnsen +6 more
TL;DR: A high-resolution profile covering the last two centuries and a discontinuous study spanning the complete last glacial-interglacial cycle of methanesulfonate (MSA) (CH3SO3−) and sulfate were obtained along Summit (central Greenland) ice cores as discussed by the authors.
