Development of Deep Sea Profiling Float: Challenges and Technology Demand

The technology developments towards ocean observation have been emerging progressively. The autonomous platform of Argo float brought revolution in ocean observation. The international Argo program facilitates and made possible to fill the gaps across the global ocean and enabled continuous observation of global ocean in real time for the collective study. Nevertheless, the present Argo floats technology available up to subsurface column of 2000 m depth which is only 50% of average depth of the ocean. The 70% of ocean coverage in the earth planet will largely influence the earth climate system especially the deep ocean plays an import role in earth's climate system. The complete information of ocean can be explored only if we have comprehensive study of ocean from top to bottom. The deep sea profiler float is one of the efforts towards such a comprehensive observation. In this paper we discussed about the design and development of deep sea profiling float, its challenges and technology demand.
