Geochemical signatures of pingo and ground ice in Grøndalen, West Spitsbergen

Three permafrost cores including one pingo (core#9) were drilled in spring 2017 and 2018 in Grøndalen, West Spitsbergen near Barentsburg. The cores were analysed for major ions and stable water isotopes. From one of the borehole (borehole#9) ground temperature data were obtained on 12 September 2018.

2017年及2018年春季，在巴伦支堡附近的西斯匹茨卑尔根的格伦达尔恩地区，成功钻取了三根永冻土芯样本，其中包括一根为冰丘（芯编号#9）。这些芯样本经分析，对其主要离子和稳定水同位素进行了研究。此外，从编号为#9的钻孔中，于2018年9月12日获得了地下温度数据。
