Dear Jonathan and Sebastien, Thank you both again. The NEMO names are now agreed and they are accepted for publication in the standard name table. The next update is planned for 26th June. N.B. I will also amend the definition of sea_water_mass_per_unit_area_expressed_as_thickness because it cross-references with steric_change_in_sea_surface_height.
I have some comments about Jonathan's proposal for steric mean sea level changes. I'll put those in a separate thread.
