Stable oxygen isotopes composition (δ¹⁸O) in modern syngenetic ice wedges (recent ice veinlets - i.e. modern ice veins formed during the last 60-100 years and penetrated into older Holocene syngenetic ice wedges) in islands of Russian East Arctic

Stable isotopes of Kotelny Island were measured at the Isotope Laboratory of the Faculty of Geography of Moscow University. The analysis was performed on a Finnigan Delta-V Plus mass spectrometer with a standard gas-bench option and the results were calibrated against international (V-SMOW and SLAP) and laboratory standards, with internal 1σ errors of ±0.6 ‰ for δ2Н and ±0.1 ‰ for δ18O, jf Bolshoy Lyakhovsky and Bunge Islands in the isotope laboratory of the Institute for Polar and Marine Research Alfred Wegener, Potsdam using mass-spectrometer Finnigan MAT Delta-S. Measurement errors of oxygen are ±0.10‰. δ¹⁸O values in modern incipient syngenetic ice wedges in islands of Russian East Arctic, modified and complemented after Vasil'chuk, (1992).

科捷利内岛（Kotelny Island）的稳定同位素样品测试工作由莫斯科大学地理学院同位素实验室完成。测试采用搭载标准气体进样装置的芬尼根Delta-V Plus型质谱仪（Finnigan Delta-V Plus mass spectrometer），测试结果以国际标准（V-SMOW与SLAP）及实验室内部标准进行校准；其中δ²H的内部1σ误差为±0.6‰，δ¹⁸O的内部1σ误差为±0.1‰。针对博尔肖伊利亚霍夫斯基岛（Bolshoy Lyakhovsky Island）与邦吉岛（Bunge Island）的同类测试，则由位于波茨坦的阿尔弗雷德·魏格纳极地与海洋研究所（Alfred Wegener Institute for Polar and Marine Research）同位素实验室开展，所用仪器为芬尼根MAT Delta-S型质谱仪（Finnigan MAT Delta-S mass spectrometer），该批次氧同位素的测量误差为±0.10‰。本数据集包含俄罗斯东极群岛地区现代初生同生冰楔的δ¹⁸O值数据，系根据瓦西尔丘克（Vasil'chuk，1992）的研究成果修改并补充完善。
