+==== ROBUSTNESS-8 / Mercator Océan - Improve split-explicit free surface ====
+'''                 Motivation: '''There are several aspects that need to be investigated concerning the robustness of current split-explicit algorithm:
+
+- Tracer conservation issues (all time splitting options do not ensure global and local tracer conservation).
+
+- Missing correction terms in the barotropic equations relative to internal pressure gradients. This would reduce mode splitting error, hence improve stability.
+
+- Work on the stability of barotropic time stepping (based on INRIA's work) to possibly remove time filtering of barotropic variables. This would limit the temporal dissipation and greatly ease online coupling of nested domains at barotropic level (with AGRIF).
