Measurements of the dissociation pressure of nitrogen hydrate and oxygen hydrate show that the clathrate hydrate of air with the formula (N(2), O(2)) 6H(2)O should exist below about 800 meters in the Antarctic ice sheet. This accounts for the disappearance of gas bubbles at depths greater than 1200 meters. The hydrate should exist from this depth to prise 0.06 percent of the ice.
对氮水合物和氧水合物离解压的测量表明，化学式为（N(2)，O(2)) 6H(2)O 的空气包合物应该存在于南极冰盖以下约 800 米处。这解释了在大于 1200 米的深度处气体气泡消失的现象。这种水合物应该存在于这个深度到占冰的 0.06%的范围内。
