Almost twenty years have been passed since the beginning of Argo programme to construct global ocean observing system. The Argo observing system have been covering the global ocean with more than 3000 Argo floats with collaboration of many countries. The Argo is well known as one of the best practices of ocean observing systems, as lots of scientific results and social/industrial benefits have been gained based on indispensable huge amount of oceanic data which has never obtained before. Recently, the Argo observing system is rapidly expanded to monitor deeper ocean (Deep Argo; >4000m depth) and bio-geochemical parameters (Biogeochemical Argo) in addition to upper layer temperature and salinity (Core Argo; <2000m depth).
On the other hand, sustainability of the Argo is not guaranteed and its observing array is still developing as international infrastructure. For example, Argo float distribution recently tends to be inhomogeneous since a part of float deployment and operation is still conducted by voluntary works. Therefore, improving the observing systems to be more effective and sustainable is a mandatory task in the oceanographic community. In this background, various efforts are forwarded to evaluate impacts of ocean observations by the support of GODAE OceanView which is endorsing the Argo programme. In coming OceanObs19, development, expansion and enhancement of the sustainability of the Argo observing systems will be discussed based on scientific results and application researches.
In this session, current status, recent issues, future works on large-scale ocean observing systems are discussed in related to Argo and other research infrastructures such as GO-SHIP, OceanSITES etc., focusing on the global ocean observing system in coming next decade.
