δ¹⁸О, δ²Н and Dexc in Holocene and modern ice wedges on the east coast of the Daurkin Peninsula, Chukotka

Values of δ¹⁸О, δ²Н and dexc in ice of Holocene and modern ice wedges on the east coast of the Daurkin Peninsula, Chukotka.Stable isotope ratios (δ¹⁸О and δ²H) were analyzed at the stable isotope laboratory of the Faculty of Geography in the Lomonosov Moscow State University (headed by Prof. Yu. Vasil'chuk) using a Finnigan Delta‐V Plus mass spectrometer applying equilibration techniques. International standards (V ‑ SMOW, GRESP, SLAP) were used for calibration. The values are presented in δ‐notation in per mil (‰) relative to the Vienna Standard Mean Ocean Water (VSMOW) expressed in per mil (‰). Analytical precision was ±0.1‰ for δ¹⁸О and±0.8‰ for δ²H.

楚科奇多尔金半岛东海岸全新世及现代冰楔冰体中的δ¹⁸О、δ²Н及氘盈余（dexc）数值。本数据集的稳定同位素比值（δ¹⁸О与δ²Н）由莫斯科罗蒙诺索夫国立大学地理学院稳定同位素实验室（尤·瓦西尔丘克教授主持）采用Finnigan Delta-V Plus质谱仪，通过平衡技术完成分析。校准过程采用国际标准物质（V-SMOW、GRESP、SLAP）。所有数值以δ标记法的千分比（‰）形式呈现，相对维也纳标准平均海洋水（VSMOW），单位为千分比（‰）。本次分析的精度为：δ¹⁸О的误差范围为±0.1‰，δ²Н的误差范围为±0.8‰。
