摘要： 海洋吸收了工业化以来大约30%人为二氧化碳(简称人为碳, Anthropogenic carbon dioxide, Cant)而显著地影响了全球海洋碳源汇格局。据估计, 南大洋35°S以南区域吸碳潜力占全球大洋高达40%左右, 但该估计也被认为存在着很大的不确定性, 主要是因为缺乏对Cant在南大洋吸收、分布、储存和输运方面的系统性认知。本文基于国内外有关南大洋碳吸收和储存及输送等数据库和研究, 分别从海-气界面CO2通量角度和海洋内部Cant的分布、储存和输送等方面, 综述归纳了南大洋开阔大洋区及近岸区碳源汇格局的研究进展; 探究目前在南大洋碳汇模型与实测数据存在明显差距原因, 以及季节性冰区碳源汇强度估算不确定性较大的问题; 讨论了相关方法在人为碳计算中的优点与不足以及影响人为碳储量的主要输送机制。本文将有助于对南大洋海-气CO2通量、源汇格局变异以及输出过程的进一步了解, 以及更准确估算南大洋乃至全球海洋碳汇。

Abstract: The Southern Ocean has the potential to uptake as much as 40% of the global ocean's carbon, but this estimate is uncertain due to the lack of systematic knowledge of anthropogenic CO2 uptake, distribution, storage, and transportation. This paper summarises research on carbon uptake, storage, and transport in the Southern Ocean, based on domestic and international databases and studies. It explores the carbon source and sink patterns in the open ocean and nearshore areas of the Southern Ocean in terms of CO2 fluxes at the sea-air interface and the distribution, storage, and transport of anthropogenic CO2 within the ocean. The paper also examines the reasons for the discrepancy between the current carbon sink model and the measured data in the Southern Ocean, as well as the uncertainty of the estimation of carbon source and sink strengths in the seasonal ice zone. Additionally, it evaluates the advantages and shortcomings of relevant methods for calculating anthropogenic carbon and the main transport mechanisms affecting the anthropogenic carbon inventory. This paper aims to enhance comprehension of sea-air CO2 fluxes, source-sink variability, and export processes in the Southern Ocean. This will aid in more precise estimations of the carbon sinks in the Southern Ocean and the global ocean.
