对美国西部三个封闭盆地湖泊的/sup 14/C:/sup 12/C比率的长期监测，得出了CO/sub - 2/平均入侵率的可靠估计。当标准化到海平面压力时，金字塔湖的结果是6 mol m/sup -/2 yr/sup -/1，沃克湖是17 mol m/sup -/1，莫诺湖是38 mol m/sup -/1。除Mono湖外，这些源自炸弹/sup 14/ c的入侵率与来自天然放射性碳分布的入侵率一致。两种方法估算的Mono湖入侵率差异较大的原因是无/sup 14/ c的泉水涌入了该湖。造成三个湖泊CO/sub - 2/入侵率差异的可能原因是风速、盐度和pH。
Long term monitoring of the /sup 14/C:/sup 12/C ratio in three closed-basin lakes in the western United States has resulted in reliable estimates of the mean CO/sub 2/ invasion rates. When normalized to sea level pressure the results are 6 mol m/sup -/2 yr/sup -/1 for Pyramid Lake, 17 for Walker Lake, and 38 for Mono Lake. Except for Mono Lake, these bomb /sup 14/C-derived invasion rates are consistent with those derived from the distribution of natural radiocarbon. The big difference in the invasion rates estimated for Mono Lake by the two methods is attributed to the influx of /sup 14/C-free spring waters to the lake. Possible causes for the difference in CO/sub 2/ invasion rates among the three lakes are wind velocity, salinity, and pH.
