抽象的。我们在这里描述，文件，并提供了广泛的数据集用于年层识别冰芯从DYE-3，GRIP，NGRIP，
NEEM和EGRIP。这些数据来自40多年来对主要深岩心和浅岩心进行的详细测量，
由几个国家的研究小组开发的不同装置，包括切割冰样品的离散测量和连续流测量
分析数据。在2005年格陵兰冰芯年表的构建过程中，这些数据系列被用于计算6万年前的年层
（GICC 05）和/或修订后的GICC 21，目前仅能追溯到3800年前。现在，基础数据已经可用（如表1所示），我们还发布了
基于这些数据集的GICC 05时标的各个年层位置。我们希望数据集的发布将促进利用这些高分辨率数据系列对过去气候的进一步研究
覆盖了格陵兰冰盖内部的大部分区域。
Abstract. We here describe, document, and make available a wide range of data sets used for annual-layer identification in ice cores from DYE-3, GRIP, NGRIP,
NEEM, and EGRIP. The data stem from detailed measurements performed both on the main deep cores and shallow cores over more than 40 years using many
different setups developed by research groups in several countries and comprise both discrete measurements from cut ice samples and continuous-flow
analysis data. The data series were used for counting annual layers 60 000 years back in time during the construction of the Greenland Ice-Core Chronology 2005
(GICC05) and/or the revised GICC21, which currently only reaches 3800 years back. Now that the underlying data are made available (listed in Table 1) we also release
the individual annual-layer positions of the GICC05 timescale which are based on these data sets. We hope that the release of the data sets will stimulate further studies of the past climate taking advantage of these highly resolved data series
covering a large part of the interior of the Greenland ice sheet.
