Evolving Argo

Argo's design needs to adapt as technologies and requirements change. A new global design is under development, which includes three elements: driving towards spatial completeness; increasing regional resolution in key areas; major new missions. Pilots of these are underway and will help inform how Argo's new design is refined.

Towards spatial completeness

Argo is evolving its global coverage plan to include polar regions and marginal seas, which were not initially part of Argo's original design due to technological limitations and high float losses in these regions. Now, operation of floats in these areas is feasible. The concept of Argo is of a spatially complete global array. Therefore, including seasonal sea-ice zones and marginal seas, moves the target number of Argo floats from 3000 to 3800.

Increasing regional resolution

Our user community has identified two regions where Argo's current sampling is not meeting requirements due to important faster and high spatial scale phenomena. The equatorial regions and western boundary currents and their extensions are two such areas, where enhanced Argo densities might be required.

Major new missions

Adapting Argo to start sampling biogeochemical parameters and the deep ocean, involves major sensor, platform and resource challenges.
