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).本研究针对科特列尼岛（Kotelny Island）的稳定同位素（stable isotope）样品，于莫斯科大学地理学院同位素实验室开展测试分析。测试采用配备标准气体预处理台的芬尼根Delta-V Plus型质谱仪完成，测试结果以国际标准（V-SMOW与SLAP）及实验室标准进行校准，内部1σ误差为：δ²H的误差范围为±0.6‰，δ¹⁸O的误差范围为±0.1‰。针对大利亚霍夫斯基岛（Bolshoy Lyakhovsky Island）与邦格群岛（Bunge Islands）的样品测试，则于波茨坦阿尔弗雷德·魏格纳极地与海洋研究所同位素实验室进行，采用芬尼根MAT Delta-S型质谱仪完成分析，其氧同位素测量误差为±0.10‰。俄罗斯东极群岛地区现代初生同生冰楔的δ¹⁸O值数据集，经Vasil'chuk（1992）的研究成果修改与补充完善。
