Taylor Dome Ice Core Data

Abstract: The collection site is Taylor Dome, an ice-accumulation area on the East Antarctic ice sheet. The dome is a ridge about 20 x 80 km, which lies inland of the Transantarctic Mountains. Deep drilling by the Polar Ice Coring Office (PICO) at Taylor Dome reached bedrock at a depth of 554 meters during the 1993-1994 austral summer season.

<p>This data set includes mesurements of:</p>
<ul>
<li>beryllium-10 (betd.txt)</li>
<li>oxygen isotopes (hi18o_td.txt and lo18o_td.txt)</li>
<li>deuterium isotopes (deld_20cm.txt and deld_td.txt).</li>
</ul>
<p>These data were produced at the University of Washington from samples obtained in the field and via the University of New Hampshire automatic melting system. For beryllium, deuterium, and 20-cm oxygen isotope data, the st9810 ice age (kyB1950) timescale is used. For 0.5- to 1-m oxygen isotope data, the st9507 is used.</p>

摘要：本数据集的采样点位为泰勒穹顶（Taylor Dome），即东南极冰盖的一处积冰区域。该穹顶为长约20×80千米的山脊，坐落于横贯南极山脉（Transantarctic Mountains）内陆区域。1993至1994年的南极夏季期间，极地冰芯钻探办公室（Polar Ice Coring Office, PICO）在泰勒穹顶开展深层钻探，于554米深度处抵达基岩。

本数据集包含以下测量内容：
- 铍-10（beryllium-10）：对应数据文件为betd.txt
- 氧同位素：对应数据文件为hi18o_td.txt与lo18o_td.txt
- 氘同位素：对应数据文件为deld_20cm.txt与deld_td.txt。

上述数据由华盛顿大学（University of Washington）基于野外采集的冰芯样品，结合新罕布什尔大学（University of New Hampshire）的自动融样系统完成分析制备。其中，铍-10、氘以及20厘米深度氧同位素数据采用st9810冰芯年代标尺（kyB1950）进行定年；0.5至1米深度的氧同位素数据则采用st9507年代标尺。
