As an interest to the greenhouse gases has increased, oceanic CO₂ observations have been actively done during many projects in the world, and lots of data analyses have suggested air-sea CO₂ exchange in various temporal and spatial scales. There are some difficulties of data exchange, however, not only for CO₂ data but also for other chemical oceanographic data. To share and fully open the data, an effective data management method has become much important. For more active and free data exchange, Japanese scientist group has established "Inventory for Chemical oceanographic Data (IJCD)" since 2000. Main purpose of IJCD is to rescue scattered data in the institutes and to establish the inventory database system in order to encourage the exchange of the data among researchers, who interests in chemical oceanographic research. It is also important activity of IJCD to consult on the development of the data format of the chemical oceanographic data with meta-data, which contains items used for inventory. For efficient collection of data inventory, IJCD cooperates with national and international activities concerned. IJCD data inventory will be public via web site, and will be linked with real data, which can be fully opened.
