Perhaps this is a use case where aliases could help.
I remember making this same argument for a term many years ago, and being told the reason for using the semantically modeled term is that *everyone else* who isn't in the field will recognize it.
Wouldn't it be the best of both worlds if both the semantic term, and the domain-familiar term, could be considered acceptable?
I think that sound I heard may have been glass shattering from the collective CF shriek. :-)

I didn't comment because I as a semantic modeller I can see both sides. However, I think you're right and Wally Broecker's work is so well absorbed into biogeochemistry that we should respect his terminology.
