Air entrapped in bubbles of cold ice has essentially the same composition as that of the atmosphere at the time of bubble formation. Measurements of the methane concentration in air extracted by two different methods from ice samples from Siple Station in western Antarcitica allow the reconstruction of the history of the increase of the atmospheric methane during the past 200 years.
被困在冷冰气泡中的空气与气泡形成时大气的成分基本相同。通过两种不同方法从南极洲西部的 Siple 站的冰样本中提取的空气的甲烷浓度测量结果,使得重建过去 200 年大气甲烷增加的历史成为可能。
