!     main parameter file which sets ocean characteristics:

!     nvar   = number of prognostic variables
!     lseg   = maximum number of longitudinal stream function segments
!     nlatpr = maximum number of latitudes for matrix printouts
!              on diagnostic time steps
!     nhreg  = number of regions in the horizontal used for averaging
!              tracers.
!     nvreg  = number of regions in the vertical used for term balance
!              calculations. note "nvreg" is not used for tracer
!              averages
!     numreg = total number of regions ( = product of nhreg & nvreg)
!              used for term balance calculations

!     nvarbh = number of prognostic variables using biharmonic mixing

!     ncrows = number of calculated rows within the MW.
!              (the remaining rows are buffer rows).

!     rstd   = standard c14/c12 ratio
