被困在冰盖表面附近的气泡在一定深度以下转化为空气水合物，它们的体积和数量随环境和气候的变化而部分变化。用显微镜观察了富士山冰芯120 ~ 2200 m深度的气泡和水合物。该深度范围涵盖全新世/末次冰期/末次间冰期/前冰期。1100米以下未见气泡，600米左右开始出现空气水合物。观察到的气泡和水合物的数量与在沃斯托克冰芯中发现的相似。然而，对于覆盖末次盛冰期的冰，Dome F核心的水合物浓度约为Vostok核心的一半。雪的变质作用和堆积作用并不能解释这一发现。
Abstract Air bubbles trapped near the surface of an ice sheet are transformed into air hydrates below a certain depth Their volume and number varies partly with environment and climate. Air bubbles and hydrates at 120-2200 m depth in the Dome Fuji (Dome F) ice core were examined with a microscope. This depth range covers the Holocene/Last Glacial/Last Interglacial/Previous Glacial periods. No air bubbles were seen below about 1100 m depth, and air hydrates began to appear from about 600 m. The observed number of air bubbles and hydrates was similar to that found in the Vostok ice core. For the ice covering the Last Glacial Maximum period, however the hydrate concentration in the Dome F core is about half that of the Vostok core. Reference to snow metamorphism and packing does not explain this finding.
