[ACG47-P06] OneArgo and implementation strategies in JAMSTEC
Keywords:Integrated Ocean Observation, Research infrastructure
OneArgo, proposed in the OceanObs19, is the global ocean observation project to extend from the Core Argo array, which measures sea water temperature and salinity in the upper 2000 m, including deep ocean (Deep), seasonal sea ice area (Polar), and marginal seas with increasing the density of observations in the tropical and western boundary current regions, and to include bio-geochemical parameter (BGC; dissolved oxygen, nitrate, pH, chlorophyll-a, backscatter and downward irradiance). The OneArgo was adopted as a project of the UN Decade of Ocean Sciences starting in 2021. The AST (Argo Steering Team), which manages international Argo programme, aims to achieve each mission's target number of active floats by 2030. A systematic data flow and quality control system has been established to implement real-time and delayed quality control of data, which is essential for a fundamental observation network for Argo. Efforts are still being made to implement and upgrade data quality control methods, including Deep, Polar and BGC Argo missions.
In order to maintain and develop the OneArgo, JAMSTEC is implementing deployments of Core, Deep, and BGC Argo float mainly in the North Pacific and Southern Ocean every year, as well as implementing the Pacific Argo Regional Center (PARC) to monitor float operation and deployment status in the Pacific region north of 30 S. In addition, for the advanced ocean observation network including the next generation Argo, new BGC sensor development such as a fast flash excitation fluorescence spectrometer (FRRF) capable of accurate primary production estimation, and preparation for the global deployment plan (ArgoMIX) of floats equipped with turbulence sensors are underway. The advanced implementation of OneArgo also requires consideration of sensor accuracy, long-term stability, and data quality control methods, and the challenge is to deal with the significant increase in complexity and workload toward the future. In this presentation, the current status of the integrated ocean observation network surrounding OneArgo will be described including collaboration with ship, mooring, satellite observations, and how JAMSTEC is addressing these issues.
