An empirical model of carbon flux and (14)C-derived ages of the water in the Canada Basin of the Arctic Ocean as a function of depth was used to estimate the long-term rate of primary production within this region. An estimate can be made because the deep waters of the Canadian Basin are isolated from the world oceans by the Lomonosov Ridge (sill depth about 1500 meters). Below the sill, the age of the water correlates with increased nutrients and oxygen utilization and thus provides a way to model the average flux of organic material into the deep basin over a long time period. The (14)C ages of the deep water in the Canada Basin were about 1000 years, the carbon flux across the 1500-meter isobath was 0.3 gram of carbon per square meter per year, and the total production was 9 to 14 grams of carbon per square meter per year. Such estimates provide a baseline for understanding the role of the Arctic Ocean in global carbon cycling.
采用了一个碳通量经验模型和（14）C 衍生的北冰洋加拿大海盆水深相关的水龄模型，以此来估算该区域的长期初级生产力速率。之所以能够做出这样的估算，是因为加拿大海盆的深水区被罗蒙诺索夫海岭（海脊深约 1500 米）与世界其他海洋隔开。在海脊以下，水的年龄与增加的营养物质和氧气利用率相关，因此为在长时间内对有机物质进入深海盆地的平均通量建模提供了一种方法。加拿大海盆的深水（14）C 年龄约为 1000 年，穿过 1500 米等深线的碳通量为每平方米每年 0.3 克碳，总生产力为每平方米每年 9 到 14 克碳。这样的估算为了解北极海洋在全球碳循环中的作用提供了一个基准。
