[ACG44-04] Autonomous ocean observations and importance of shipboard observations: the future of ocean observing systems (Discussion)

Keywords:Ocean observation, Integrated observing system in the future, observation platform

Observations in the global ocean are essential for understanding the actual state of the interior ocean, even with the recent advances in analysis and forecasting of the ocean using high-resolution numerical models. Like the Argo (including deep and BGC Argo) as a global ocean observation network, which measures temperature and salinity in the upper ocean, it is expected that other parameters will be shifted to an autonomous ocean observation system from ship or other platforms. On the other hand, for microstructural physics and chemical parameters that require water sampling and precise measurements, with shipboard observations are still crucial at present. Under such circumstances, the shipboard observations themselves are becoming more and more difficult to conduct regularly due to recent inflation of fuel oil, reduced human and material resources in the world.
Both autonomous observations and shipboard observations have their own advantages, therefore, many people believe that the integrated observation platform should be developed, in which the advantages of both platforms can be utilized in a comprehensive manner. With limited resources, it is necessary to consider how much to focus on and balance automatic and shipboard observations in the future, taking into account to progress marine science and technology in the future.
Argo and other automated ocean observing systems are moving towards obtaining higher quality and multiparameter data, particularly driving in Europe and the USA. We would like to share information on these situations, review the complementarities and uniqueness of current observation systems, and discuss the ocean observations with lots of researchers.
