The surface ocean is active in biological processes and important for the biogeochemical cycles, especially for CO_2. We have studied the problems in the western and eastern sides of the North Pacific, applying calibrated methods by both the American and Japanese scientists. We have discussed the results obtained by the both groups. The most important point is a great contrast between the western and the eastern parts, which is causes by dissolved silica contained in the deep water.

表层海洋在生物过程中十分活跃，对生物地球化学循环特别是CO_2循环具有重要意义。我们利用美国和日本科学家的校准方法，研究了北太平洋西岸和东部的问题。我们讨论了这两个小组所取得的结果。最重要的一点是，西部和东部的差异很大，这是由于深水中含有溶解的二氧化硅造成的。
