Hi Keith, I see your point about the N2 production not being part of the regenerated production. However, I would say the same is true of NH4 from deposition, runoff or supply from below, and the opposite true with respect to NO3 nitrified in the euphotic zone - all of which leaving 'new' with ambiguous meaning. I have always treated N2 production separately from new production in my own thinking for model-data comparisons of new production traditionally being measured from NO3 incubations. Perhaps we should change the name from 'pnew' to 'pno3' to avoid confusion...?
