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.
