Dear Barna,
Perhaps the existing Standard Name would suffice for Cathy's needs as she is labelling model output and the models in my experience do not work to a specific measurement scale. This is because boundary condition and assimilation data sets can include measurements of more than one type in order to provide adequate coverage.
Cheers, Roy.
I have now retired but will continue to be active through an Emeritus Fellowship using this e-mail address.

Hi Cathy,
There is already the name `sea_water_salinity_at_sea_floor` in the CF standard name list. However, if you know the scale you are calculating, a new name should be added to indicate this:
sea_water_practical_salinity_at_sea_floor if using PSS-78
or
sea_water_absolute_salinity_at_sea_floor if using TEOS-10
I can come up with some definitions if you would like to have either of these proposed to the list.
