Microparticle, Conductivity, and Density Measurements from the WAIS Divide Deep Ice Core, Antarctica

Abstract: This data set includes microparticle concentration, electrical conductivity, and density measurements from the West Antarctic Ice Sheet (WAIS) Divide deep ice core, WDC06A. Microparticle concentration data are reported as total particles per ml of meltwater. Concentration was measured using a laser detector and the University of Maine WAIS Melt Monitor system. Conductivity is measured in micro-Siemens per cm (uS/cm). Density data were collected on 3 by 3 by 100 cm sticks from the WDC06A core, using the Maine Automated Density Gauge Experiment (MADGE). Density data span 0 to 160 m in depth, while the particle and conductivity measurements span the upper 577 m of the core.

Data are available via FTP in ASCII text format (.txt).

摘要：本数据集涵盖取自南极西部冰盖（West Antarctic Ice Sheet，WAIS）分水岭深冰芯WDC06A的微粒浓度、电导率与密度三类测量数据。其中微粒浓度数据以每毫升融水中的总颗粒数为计量单位，采用激光探测器与缅因大学WAIS融水监测系统完成测定。电导率的测量单位为微西门子每厘米（μS/cm）。密度数据采集自WDC06A冰芯的3×3×100 cm冰样柱，通过缅因大学自动化密度测量实验（Maine Automated Density Gauge Experiment，MADGE）系统获取。密度数据的覆盖深度范围为0至160米，而微粒浓度与电导率测量数据则覆盖该冰芯上部577米的深度区间。
