摘　　要：2016年10月正式实施的国际BGC-Argo计划是第一个有能力监测全球生物地球化学过程的项目,弄清其观测数量、数据特征及分布情况,有助于后续充分利用这些宝贵观测数据提高对海洋酸化、海洋碳循环及低氧区变动等严重影响海洋生态系统健康问题的认知。本文系统地统计了全球及几个实验区的Argo溶解氧数据的数量、站位分布、浮标数据类型、数据密度等情况。结果显示,截止到2019年底,全球海域由BGC-Argo浮标获取的溶解氧剖面总数已超过17万条,且每年持续递增约1万条;溶解氧观测资料空间分布不均匀,全球海域共有36.8%的网格点满足空间分辨率为1°的客观分析要求,而五个试验区观测数据更集中。International BGC-Argo,which has been implemented officially since October,2016,is the first project that have the capability to monitor the global biogeochemistry.Therefore,understanding the number of its observation,the characteristics and the distribution of the data is very helpful for the subsequent use fully to improve our cognition on ocean acidification,marine carbon cycle as well as hypoxic zone variation,which influence the health of marine ecosystem significantly.In this paper,systematic statistics were made about the number and distribution of Argo dissolved oxygen data,the types of buoy data and the density of the data in the global ocean as well as several experimental areas.The results showed that until the end of 2019,the total number of dissolved oxygen profiles,which were acquired by BGC-Argo buoys in global ocean,accumulated to 1 hundred and 70 thousand and was increasing by 10 thousand per year.The spatial distribution of dissolved oxygen observation data was uneven.Only 36.8% of global grid points met the analysis need of spatial resolution of 1 degree objectively,and this kind of data which met the resolution need was more observed in five experimental areas.
