Physical Properties of the Greenland Ice Sheet Project II (GISP II) Core

该奖项支持第二个格陵兰冰盖项目(GISPII)的一个方面。GISPII的目标是对格陵兰岛顶峰附近将要钻探的深部岩芯进行恢复和古气候解释。这些研究将确定核心的特征，并验证其地层连续性(或确定不连续点)，这是进行任何古气候分析的先决条件。这些研究还将有助于更好地理解冰的变形及其对织物、杂质浓度、颗粒大小和其他因素的依赖。要收集的数据包括：视觉分层、密度、质地(颗粒和气孔的大小、形状和排列)和织物(c轴方向)。

This award supports one aspect of the second Greenland Ice Sheet Project (GISPII). The goal of GISP II is the retrieval and paleoclimatic interpretation of a deep core to be drilled near Summit, Greenland. These studies will characterize the core and verify its stratigraphic continuity (or identify discontinuities), prerequisites to any paleoclimatic analyses. These studies also will lead to a better understanding of the deformation of ice and its dependence on fabric, impurity concentrations, grain size, andother factors. Data to be collected include: visual stratification, density, texture (size, shape and arrangement of grains and pores) and fabric (c-axis orientations).
