我们对格林兰冰芯计划（GRIP）深冰芯中的空气包合物进行了拉曼光谱实验。我们提出了新的N-2/O-2测量，显着不同于以前的染料-3冰芯的测量：我们观察到的N-2/O-2比更接近大气。这对解释冰盖中的气体分布和重建过去的大气条件具有新的意义。
We have carried out Raman spectroscopic experiments on air clathrates in the GReenland Ice Core Project (GRIP) deep ice core. We present new N-2/O-2 measurements that markedly differ from previous measurements of the Dye-3 ice core: the N-2/O-2 ratio we observe is much closer to atmospheric. This has new implications for the interpretation of gas distributions in ice sheets and the reconstruction of past atmospheric conditions.
