Multi-site ice core Krypton stable isotope ratios

Abstract: Stable isotope ratios of atmospheric krypton, argon, nitrogen and oxygen were measured in late-Holocene ice core samples from nine sites in Antarctica and Greenland, for the purpose of calibrating the Kr-86 excess proxy as defined in Buizert and Severinghaus (2016).摘要：本研究针对采自南极与格陵兰9个采样点的全新世晚期冰芯样品，测定了其中大气氪、氩、氮及氧的稳定同位素比值，旨在校准Buizert与Severinghaus（2016）中定义的Kr-86过剩代用指标。
