[MITgcm-support] Query regarding BLING

[kunal madkaiker]

Thanks Matt,

I tried with #undef CARBONCHEM_SOLVESAPHE but the issue persists.

Just an observation, when I keep PTRACERS_ref=0 in data.dic, it doesn't
impact the DIC and ALK at those runoff points (ref. using_dic.gif)
However, whether I keep PTRACERS_ref=0 or any other value, it impacts the
conc. of those points (which keep on drifting as the run progresses, ref.
using_bling.gif).
