中文摘要：

海洋是全球最大的碳汇,确定海洋中人为碳含量及其时空变化是一件具有挑战性的工作。就当前海洋人为碳含量确定方法、人为碳储量及其随时间变化进行综述总结。研究表明海洋仍然可以吸收并储藏大量的人为碳,但未来对于海洋吸收储藏人为碳的研究仍具有诸多不确定性。已有证据表明稳态海洋的概念不完全正确,需要在非稳态条件下重新定义人为碳并开展研究。同时需要积累更多的观测数据,采用包括观测和模式模拟等手段来研究不同时间尺度的人为碳的吸收和储藏过程。

英文摘要：

The ocean is the largest carbon sink in the world. It is difficult to determine the content of anthro- pogenic carbon （Cant ） and the spatial and temporal distribution in the ocean. The methods of Cant determination, inventories estimation of Cant, temporal variations of Cant were summarized in this review. The ocean can still uptake and store Cant from the atmosphere. However there are still many uncertainties for the oceanic Cant uptake and stor- age studies. The evidences show that it is not true for Cant estimations based on the steady state assumption. Thus, it is necessary to define and study the Cant based on non-steady state. Meanwhile, it is necessary to collect more ob- servation data and use more approaches such as observations and model simulations to study the C ant uptake and storage in different time scales.
