Dear all, At the risk of repeating ourselves, because there are now (at least) three different salinities, it is now ambiguous and confusing to call any salinity "Salinity". The Announcement of TEOS-10 that is now appearing in all 22 oceanographic journals specifically recommends that the use of the word "Salinity" cease immediately, and that either the words "Practical Salinity" or "Absolute Salinity" be used. The reason of course is to minimise ambiguity.
So this is where the community (including CF-metadata) will have to end up:- we have been requested to do so by IOC, SCOR and IAPSO. So we may as well do it now, in my view. Note that all ocean models run to date have used Practical Salinity as their "Salinity" variable,, and all equations of state since 1980 have been in terms of Practical Salinity. So there is no slight-of-hand in calling these variables "Practical Salinity"; rather it is just being specific as to what this type of salinity always has been. That is "Practical Salinity" is simply the long-hand name of what we have been calling "Salinity" for 30 years. Trevor -----Original Message----- From: Lowry, Roy K.

It seems safe to assume they will be put in the table in due course.
