[MITgcm-support] Bryan-Lewis vertical diffusivity for passive tracers

[Martin Losch]

You are right about this, I forgot this contribution. The original KPP  
has also other contributions such as double diffusive processes (see  
Large et al 1994, starting at eq 30), but this is apparently not  
implemented (although I am sure that I havej once seen something like  
that somewhere in the code, but it must have been a fata morgana).
