Interpretation of GISP2 Electrical Conductivity Record

格陵兰冰盖项目2（GISP 2）已经从格陵兰岛中部恢复了一个冰芯，覆盖了至少10万年前的时间。 该地点的高积累率使其成为研究气候机制和变率的理想记录。 电导率是冰的酸/碱平衡的函数，它是沿岩芯连续沿着测量的，并提供了在岩芯上进行的许多测量中最高的时间分辨率。现有的电导率记录将与其他记录一起解释。 具体目标是; 1）调查十年和世纪尺度的气候变化，2）编制GISP 2核心中火山活动记录年表，3）增进对Summit地区冰流的了解，4）改进GISP 2核心的定年和积累记录，5）编制GISP 2核心记录的北方半球生物质燃烧年表。 GISP 2是NSF北极系统科学计划的一个组成部分。

The Greenland Ice Sheet Project 2 (GISP2) has recovered an ice core from central Greenland covering a time that extends at least 100,000 years before present. The high accumulation rate at the site makes it an ideal record for studying climate mechanisms and variability. The electrical conductivity, which is a function of the acid/base balance of the ice, has been measured continuously along the core and provides the highest time resolution of the many measurements which have been made on the core. The existing conductivity record will be interpreted in conjunction with other records. Specific goals are; 1) Investigation of decadal and century scale climate change, 2) Develop a chronology of volcanic activity record in the GISP2 core, 3) Improve the understanding of ice flow in the Summit region, 4) Improve the dating and accumulation record of the GISP2 core, and 5) Develop a chronology of northern hemisphere biomass burning as recorded by the GISP2 core. The GISP2 is a component of the NSF Arctic System Science Program.
