[MITgcm-support] advection of passive tracers, a never-ending story

[Martin Losch]

Dimitris, Chris,

I have now confirmed your results for my case with sBeta=0: When I turn 
off the rhs (that is, my bgc-model) salinity and ptracers look exactly 
the same (provided they have the same initial fields and forcing). So 
the noise must come from my bgc-model. Too bad ...
