利用Chen （1982a）在东北太平洋巡航期间（1981年6 - 7月）获得的ΔTCO2°结果，我们计算了阿拉斯加和夏威夷之间沿150°W的样带的工业化前和1981年方解石和文石饱和层位。在过去的130年里，海洋对过量二氧化碳的吸收导致了东北太平洋碳酸盐化学的重大变化。结果表明，在亚北极锋以北的冷水区，过饱和透镜体的厚度明显减少，方解石和文石的100%饱和水平向上平移了150米和70米。
Using the ΔTCO2° results of Chen (1982a) obtained during a cruise in the northeast Pacific Ocean (June‐July 1981), we have calculated preindustrial and 1981 calcite and aragonite saturation horizons for a transect along 150°W between Alaska and Hawaii. Uptake of excess CO2by the oceans over the past 130 years has resulted in a significant change in the carbonate chemistry of the northeast Pacific Ocean. The results indicate an apparent reduction in the thickness of the supersaturated lenses and an upward translation of the 100% saturation level by as much as 150 meters for calcite and 70 meters for aragonite in the coldwater region north of the Subarctic Front.
