NGRIP continuous ice core chemistry measurements

Selected sections of the archived NGRIP (North Greenland Ice Core Project) obtained from the University of Copenhagen were analyzed with the DRI/OSU continuous ice core analytical system largely to investigate the impact of site characteristics (accumulation rate, temperature, elevation, locations, surface melt history, impurity concentrations) on the fidelity of Greenland ice core gas (methane and carbon monoxide) records. Included in the data set are three sections of NGRIP core (~73.7 to ~110.0 m, ~207.0 to ~519.1 m, ~519.0 m to ~570.0 m). Continuous gas measurements are reported elsewhere.

本研究对从哥本哈根大学获取的存档北极格陵兰冰芯计划（North Greenland Ice Core Project，NGRIP）的部分冰芯段，采用DRI/OSU连续冰芯分析系统开展分析，核心目标为探究场地特征（包括积累速率、温度、海拔、位置、表面融化历史与杂质浓度）对格陵兰冰芯气体（甲烷与一氧化碳）记录保真度的影响。本数据集包含三段NGRIP冰芯样品：分别为~73.7至~110.0米、~207.0至~519.1米以及~519.0至~570.0米的冰芯段。连续气体测量数据的相关细节已在其他研究中报道。
