1997年7月至2001年12月在波照间岛（北纬24°3′，东经123°49′）和1998年12月至2001年12月在大石角（北纬43°10′，东经145°30′）采集的空气样品测定了O2/N2比值。基于气相色谱分析的O2/N2比值清楚地显示出下降趋势和季节变化，春季和夏季增加，秋季和冬季减少。Ochi-ishi的季节性O2/N2周期的振幅是Hateruma的两倍。Hateruma在4年期间（1998-2001年）的平均下降率为18.4 ± 1.4兆/年，Ochi‐ishi在3年期间（1999-2001年）的平均下降率为19.2 ± 1.6兆/年。
The O2/N2 ratios were determined of air samples collected at Hateruma Island (lat 24°3′N, long 123°49′E) from July 1997 to December 2001, and at Cape Ochi‐ishi (lat 43°10′N, long 145°30′E) from December 1998 to December 2001. The O2/N2 ratios, based on gas‐chromatographic analysis, clearly showed decreasing trends and seasonal variations, increasing in spring and summer, and decreasing in autumn and winter. The amplitudes of the seasonal O2/N2 cycles for Ochi‐ishi were twice as large as those for Hateruma. The average rates of decrease were 18.4 ± 1.4 per meg yr−1 over a 4‐year period (1998–2001) for Hateruma, and 19.2 ± 1.6 per meg yr−1 over a 3‐year period (1999–2001) for Ochi‐ishi.
