 The Argo program has been implemented and sustained for nearly two decades, providing continuous observations of ocean temperature and salinity versus pressure, from the sea surface to 2,000 meters deep. This was achieved through the use of cost-efficient and robust technologies of autonomous profiling floats. Recent advances in platform and sensor technologies have opened up new possibilities for extending Argos reach into deeper waters, and adding biogeochemical sensors for improved understanding of oceanic cycles of carbon, nutrients, and ecosystems. Additionally, the addition of experimental sensors could provide valuable information regarding the spatial and temporal patterns of ocean mixing. Overall, the goal is to create a fully global, top-to-bottom, dynamically complete, and multidisciplinary Argo program that will integrate seamlessly with satellite and other, in situ elements of the global ocean observing system.
