TL;DR: In this paper, a more detailed and extended version of the Greenland Stadials (GS) and Greenland Interstadials (GI) template for the whole of the last glacial period is presented, based on a synchronization of the NGRIP, GRIP, and GISP2 ice-core records.
Journal ArticleDOI
An event stratigraphy for the Last Termination in the North Atlantic region based on the Greenland ice-core record: a proposal by the INTIMATE group
Svante Björck,Michael Walker,Les C. Cwynar,Sigfus J Johnsen,Karen Luise Knudsen,J. John Lowe,Barbara Wohlfarth +6 more
TL;DR: Based on the oxygen isotope signal in the GRIP Greenland ice core, a new event stratigraphy spanning the time interval from ca. 22.0 to 11.5 k GRIP yr BP (ca. 19.0-10.0 k 14 C yr BP) is proposed for the North Atlantic region as mentioned in this paper.
Journal ArticleDOI
Formal subdivision of the Holocene Series/Epoch: a Discussion Paper by a Working Group of INTIMATE (Integration of ice‐core, marine and terrestrial records) and the Subcommission on Quaternary Stratigraphy (International Commission on Stratigraphy)
Michael Walker,Max Berkelhammer,Svante Björck,Les C. Cwynar,David A. Fisher,Antony J. Long,J. John Lowe,Rewi M. Newnham,Sun Olander Rasmussen,Harvey Weiss +9 more
TL;DR: This article proposed an Early-Middle Holocene Boundary at 8200 a BP and a Middle-Late Holocene boundary at 4200 aBP, each of which is linked to a Global Stratotype Section and Point (GSSP) to ensure consistency in stratigraphic terminology.
Journal ArticleDOI
Formal ratification of the Quaternary System/Period and the Pleistocene Series/Epoch with a base at 2.58 Ma
TL;DR: In 2009, the International Union of Geological Sciences (IUGS) formally ratified a proposal by the International Commission on Stratigraphy to lower the base of the Quaternary System/Period to the Global Stratotype Section and Point (GSSP) of the Gelasian Stage/Age at Monte San Nicola, Sicily, Italy as mentioned in this paper.

TL;DR: The Quaternary Period (130-10 ka BP) and the Last Interglacial-Glacial Cycle (10,000, 000, 000) were studied in this paper.
