[ACG47-05] Challenges in realizing OneArgo and the importance of collaboration with other observations (Discussion)

Keywords:Ocean Observation, Research infrastructure

OneArgo, proposed at OceanObs19, is a platform for integrated observation system and operation of Deep and BGC Argo float observations with Core Argo floats. The Argo community is aiming to develop the OneArgo as a new observation system in collaboration with other countries that actively commits for the Argo observing array. In addition, as adopted in the UN Decade project starting in 2021, the Argo community is also expected to collaborate with other observation platforms and new fields. In recent years, with the recent higher fuel price, reduction in human and material resources, and changes in the environment and economic circumstances, it has become increasingly difficult to conduct traditional method observations for the ocean. OneArgo is also important from the perspective of efficient operation of a common platform and the creation of new research fields and industrial activities.
In Japan, Japan Agency for Marine-Earth Science and Technology and Japan Meteorological Agency are playing a central role in the deployment and operation of Argo. Recently, not only analyzing in the ocean using Argo data being provided globally from Argo data center, but the number of research projects that have recently deployed Argo floats through research funds and that wish to be included in the Argo data flow, is increasing. In terms of technological development, the development of new sensors and floats is also being promoted and considered, and Argo is recognized as an indispensable research platform that contributes to the acceleration of Research and Development.
OneArgo has been published in “Fundamental concepts for promoting large scientific research projects” (Roadmap 2023) led by the Ministry of Education, Culture, Sports, Science and Technology (MEXT). While it is expected that the OneArgo will be accelerated as one of a big ocean science in the future, it is also necessary to urgently consider how to promote OneArgo and link it to other fields in Japan with limited resources. We would like to share information on these situations and discuss the state of ocean observation not only with senior researchers but also with young researchers.
