Nan - your statement below has me wondering about what a statistician would say.  Would they say: A "mean" is still a statistical concept, and can not be measured. It can only be computed, statistically, as sum/N.  In that sense, it is not really any different that standard deviation… the mean is where the distribution is centered, and the standard deviation is the width of that distribution.  Neither is  a discrete measurement and only make sense as part of a distribution.  But I am not a statistician so I really do wonder what one would say….

I don't think the standard deviation of the  temperature of sea water is really a
geophysical property; it's a mathematical concept, while a temperature value
represented as a mean is still a temperature.
