Yes, I see. It is good to bring it up again since it has not been resolved. I think giving a unit of 1 would be confusing and therefore not a good idea. No-one would know what was being suggested e.g. whether salinity is about 0.035 or about 35. To specify it as psu and permit this as a udunit would be much clearer, I believe. As you say, it would be good to know general opinion.
