  • Timing and climate forcing of volcanic eruptions for the past 2,500 years

  • A stratigraphic framework for abrupt climatic changes during the Last Glacial period based on three synchronized Greenland ice-core records

    Open AccessSune O Rasmussen, Matthias Bigler et al.ARTICLEQuaternary Science Reviews2014

    Due to their outstanding resolution and well-constrained chronologies, Greenland ice-core records provide a master record of past climatic changes throughout the Last Interglacial–Glacial cycle in the North Atlantic region. As part of the INTIMATE (INTegration of Ice-core, MArine and TErrestrial records) project, protocols have been proposed to ensure consistent and robust correlation between different records of past climate. A key element of th…

  • A 60 000 year Greenland stratigraphic ice core chronology

    Open AccessAndreas Svensson, K K Andersen et al.ARTICLEClimate of the Past2008

    The Greenland Ice Core Chronology 2005 (GICC05) is a time scale based on annual layer counting of high-resolution records from Greenland ice cores. Whereas the Holocene part of the time scale is based on various records from the DYE-3, the GRIP, and the NorthGRIP ice cores, the glacial part is solely based on NorthGRIP records. Here we present an 18 ka extension of the time scale such that GICC05 continuously covers the past 60 ka. The new sectio…

  • High-Resolution Greenland Ice Core Data Show Abrupt Climate Change Happens in Few Years

    Open AccessJørgen Peder Steffensen, K K Andersen et al.ARTICLEScience2008

    The last two abrupt warmings at the onset of our present warm interglacial period, interrupted by the Younger Dryas cooling event, were investigated at high temporal resolution from the North Greenland Ice Core Project ice core. The deuterium excess, a proxy of Greenland precipitation moisture source, switched mode within 1 to 3 years over these transitions and initiated a more gradual change (over 50 years) of the Greenland air temperature, as r…

  • The Mt Logan Holocene—late Wisconsinan isotope record

    Open AccessDavid Fisher, E C Osterberg et al.ARTICLEThe Holocene2008Cited by: 6References: 1

    The ice core recovered from Prospector Russell Col on Mt Logan (5.4 km a.s.l.), in the Yukon spans over 20 000 years. This unique record offers a Pacific view of the stable isotope and chemical record from the Lateglacial to the present. The timescale is based on seasonal counted years, the largest known volcanic acid signatures and the major shift in stable isotopes and chemistry at the end of the Younger Dryas. There are large and sustained cha…

  • A synchronized dating of three Greenland ice cores throughout the Holocene

    Open AccessBo Vinther, B M Vinther et al.ARTICLEJournal of Geophysical Research:…2006

    As part of the effort to create the new Greenland Ice Core Chronology 2005 (GICC05) a synchronized stratigraphical timescale for the Holocene parts of the DYE‐3, Greenland Ice Core Project (GRIP), and North Greenland Ice Core Project (NGRIP) ice cores is made by using volcanic reference horizons in electrical conductivity measurements to match the cores. The main annual layer counting is carried out on the most suited records only, exploiting tha…

  • A new Greenland ice core chronology for the last glacial termination

    Open AccessSune O Rasmussen, K K Andersen et al.ARTICLEJournal of Geophysical Research:…2006

    We present a new common stratigraphic timescale for the North Greenland Ice Core Project (NGRIP) and GRIP ice cores. The timescale covers the period 7.9–14.8 kyr before present and includes the Bølling, Allerød, Younger Dryas, and early Holocene periods. We use a combination of new and previously published data, the most prominent being new high‐resolution Continuous Flow Analysis (CFA) impurity records from the NGRIP ice core. Several investigat…

  • Oxygen isotope and palaeotemperature records from six Greenland ice‐core stations

    Open AccessSigfús J Johnsen, Dorthe Dahl‐Jensen et al.ARTICLEJournal of Quaternary Science2001

    Oxygen isotope variations spanning the last glacial cycle and the Holocene derived from ice‐core records for six sites in Greenland (Camp Century, Dye‐3, GRIP, GISP2, Renland and NorthGRIP) show strong similarities. This suggests that the dominant influence on oxygen isotope variations reflected in the ice‐sheet records was regional climatic change. Differences in detail between the records probably reflect the effects of basal deformation in the…

  • Past Temperatures Directly from the Greenland Ice Sheet

    Open AccessD Dahl-Jensen, Dorthe Dahl‐Jensen et al.ARTICLEScience1998

    A Monte Carlo inverse method has been used on the temperature profiles measured down through the Greenland Ice Core Project (GRIP) borehole, at the summit of the Greenland Ice Sheet, and the Dye 3 borehole 865 kilometers farther south. The result is a 50,000-year-long temperature history at GRIP and a 7000-year history at Dye 3. The Last Glacial Maximum, the Climatic Optimum, the Medieval Warmth, the Little Ice Age, and a warm period at 1930 A.D.…
