The Euro-Argo ONE project (HORIZON Europe) aims to provides the framework for implementing OneArgo, the global ocean observation program, at European level.

The Argo program has grown considerably, becoming today OneArgo, the largest multidisciplinary program for in situ ocean observation, including the original Core mission (temperature, salinity), as well as 3 complementary missions: BGC (essential biogeochemical variables), Deep (depths > 4,000 to 6,000 m) and Polar (ice-covered areas beyond 60° North and South). The 23 project partners of Euro-Argo ONE will contribute to strengthening the capacity of Europe to operate the network’s profiling floats and distribute qualified data in real time and very high-quality data in delayed time. The LOV OMTAB team will be involved in the development of BGC-Argo variable qualification methods and their consistent implementation at European level, as well as in society-related activities, notably the development of the Adopt-a-Float educational program.
