The Statistic for dissolved oxygen data of BGC-Argo
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 hy-poxic zone variation,which influence the health of marine ecosystem significantly.In this paper,sys-tematic 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 une-ven.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.
