[MITgcm-support] problems with ptracer package

[Martin Losch]

Dimitris,

I updated my directory tree today, after you had checked in all of the 
bug-fixes that concerned the ptracers-package, etc. Now I observe a 
peculiar new behavior: In my setup, salinity is passive (sBeta=0), but 
the value of diffK4S (biharmonic friction coefficient) affects the 
solution of the passive tracers (all of them!), GM and KPP turned off. 
I cannot find the reason (I have searced all day). Maybe you have an 
idea of what might have happened, as you have a better overview over 
the changes you made than I do?

Martin

P.S. Apparently, kappaRS is also the kappaRTr for all passive tracers, 
but PTRACERS_diffK4 should not be affected anywhere, right?
