Background and objective
Following the deployment of the first Argo floats in late 1999, the global Argo array of over 3000 instruments, including its data management system, was in place by 2007. Since that time global coverage has been sustained at about 3800 floats for over a decade, leading to a wealth of new discoveries documenting the evolving state and variability of the ocean/climate system, underpinning improved ocean forecasting, and supporting all branches of marine science. Over this period, the technology used in Argo has advanced, allowing operations in previously difficult regions: closer to the sea surface, in marginal seas, in seasonal ice zones, and over the full ocean depth. In parallel, new requirements are emerging, such as enhanced sampling in the tropics and western boundary regions. Major planned Argo enhancements include full depth sampling (Deep Argo) and the addition of new sensors (Biogeochemical Argo).
The progress of Argo has been a highlight of community discussion in both OceanObs’99 and OceanObs’09. Argo will again be in the spotlight in OceanObs’19. The OceanObs’19 Argo Community White Paper is being prepared around Core Argo, Biogeochemical (BGC) Argo, Deep Argo, Data System, and mixing measurements on Argo floats (ArgoMix). The ASW-6 is organized to prepare for Oceanbs’19 by providing an opportunity to share ideas presented in the Argo White Paper among the Argo community and to connect them to other observing networks and user communities including research/operational and other application areas. Particular objectives include:
- to share past/recent scientific and operational achievements of Argo
- to review history/development/justification/previous technology advances of Argo
- to acknowledge present status, problems to be overcome and strengths of Argo
- to discuss the future of Argo: plans for evolution and growth; anticipated technology advances
- to seek end user engagement, based on the link with operational oceanography and including connections to OceanObs’19 conference themes: e.g. climate variability and change, ecosystem health, etc.
- to consider integration with other observing system elements such as satellites, repeat hydrography, moorings, gliders, ship of opportunities, etc.
Structure and organization of the workshop
The 3 day workshop will consist of following sessions:
- Core Argo
- Deep Argo
- Biogeochemical Argo
- Argo Data System
- ArgoMix and other advanced measurements
- End user engagement
The workshop will be a mix of invited and submitted plenary talks and posters. Each session will address the objectives described above as appropriate. Contribution towards any of the workshop objectives and presentations of underpinning science and technology are encouraged.
There will be an opportunity for commercial exhibit stands integrated with science poster sessions.
Morning and afternoon breaks, the scientific poster sessions and exhibition will all be held in a common open space.
