WAISCORES Snow Pit Chemistry, Antarctica

Abstract: This data set is part of the West Antarctic Ice Sheet cores (WAISCORES) project, an NSF-funded project to understand the influence of the West Antarctic Ice Sheet on climate and sea level change. WAISCORES researchers acquired and analyzed snow pit and core samples from the Siple Dome, in the Siple Coast region, West Antarctica.

This data set includes glaciochemical spatial variability data for Siple Dome snow pits B, E, F, G, H, and 1 through 6. Samples were analyzed for soluble ion content via suppressed ion chromatography. Each pit was sampled at 2 cm resolution for ion chemistry using clean procedures, and sampled again at 3 cm resolution for density calculations. Snow pit names and locations correspond to the 1996 to 1997 season shallow core sites.

Data in this collection were obtained during two Antarctic field seasons in 1994 to 1995 and 1996 to 1997. Data are available via FTP in space-delimited ASCII text (.dat) file format.

摘要：本数据集为西南极冰芯（West Antarctic Ice Sheet cores, WAISCORES）项目的组成部分。该项目由美国国家科学基金会（National Science Foundation, NSF）资助，旨在探究西南极冰盖对气候与海平面变化的影响。西南极冰芯项目的研究人员于西南极锡普尔海岸区域的锡普尔穹丘采集并分析了雪坑与冰芯样本。

本数据集涵盖锡普尔穹丘雪坑B、E、F、G、H以及1至6号雪坑的冰化学空间变异数据。研究人员采用抑制型离子色谱法（suppressed ion chromatography）对样品的可溶性离子含量进行分析。每个雪坑以2厘米分辨率采样以开展离子化学分析，并以3厘米分辨率再次采样用于密度计算。所有雪坑的名称与位置均对应1996至1997年野外季的浅冰芯采样点位。

本数据集的采集工作分别在1994至1995年与1996至1997年两次南极野外季中完成。数据可通过文件传输协议（File Transfer Protocol, FTP）获取，格式为空格分隔的ASCII文本文件（.dat）。
