Newall Glacier Snow Pit and Ice Core, 1987 to 1989

Snow pit and ice core data from the Newall Glacier (location - 162 30'
East, 77 35' South) were collected during 1987 and 1988. These include
information on chemistry, Beta profiles and stratigraphy. Ice cores
were collected during the austral summer of 1988-1989 and contain
information on chemistry, Pb- 210 profiles, density profiles and
temperature profiles. Core A was 175 meters long and core B was 150
meters long.

The snow pits were dug and sampled by the Glacier Research Group
(GRG), using established protocols to prevent contamination. The
samples for major ion chemistry remained frozen until melted for
analysis in the GRG lab, located at the University of New Hampshire
(UNH), and all core processing was done by GRG established protocols
to prevent contamination. Major ions were analyzed using suppressed
ion chromatography.

1987年至1988年间，研究人员采集了纽瓦尔冰川（Newall Glacier，坐标：东经162°30′，南纬77°35′）的雪坑与冰芯数据。该数据集涵盖化学组分、β剖面（Beta profiles）与地层学信息。1988-1989年南半球夏季采集的冰芯则包含化学组分、铅-210（Pb-210）剖面、密度剖面与温度剖面信息，其中A号冰芯长175米，B号冰芯长150米。
雪坑的挖掘与采样工作由冰川研究小组（Glacier Research Group, GRG）依照既定标准操作规程开展，以避免样本污染。用于主要离子化学分析的样品在设于新罕布什尔大学（University of New Hampshire, UNH）的GRG实验室进行融化分析前，始终保持冷冻状态；所有冰芯处理流程均遵循GRG制定的防污染标准操作规程。主要离子采用抑制型离子色谱法完成检测分析。
