Implemented a new option, CLIMA_TS_MIX, to diffuse tracer perturbation (t-tclm) instead of tracer (t) field alone. This option can be used in some applications to reduce the numerical diapycnal mixing of tracer in deep waters. This strategy has been used extensively in other models. For example, see Mellor and Blumberg, 1985.

The is a bug in step_floats.F when computing the vertical position for isobaric (flt_Isobar) or geopotential floats (flt_Geopot). The k-loop in lines 265 and 441 should be:

            DO k=N(ng)-1,0,-1

instead of:

            DO k=N(ng)-1,1,-1

Notice that the interpolated value (cff6) for k=N(ng) needs to be computed first outside this loop.

Updated varindo.dat and mod_ncparam.F to include the metadata for cohesive and noncohesive input boundary variables. Recall the the logic for these variables are special because it depends on the number of sediment classes. I added the following comment to varinfo.dat for clarity:

!
!------------------------------------------------------------------------------
!  Sediment variables:  The actual variable name for some of the sediment
!                       tracers are set-up internally in "mod_ncparam.F".
!  It depends on the mumber of cohesive and noncohesive sediment tracers
!  for a particular application. For example if you have 1 cohesive and
!  2 noncohesive sediment classes, the variable names are:
!
!    "mud_"          becomes   "mud_01"
!    "mud_west_"     becomes   "mud_west_01"
!    "mud_east_"     becomes   "mud_east_01"
!    "mud_south_"    becomes   "mud_south_01"
!    "mud_north_"    becomes   "mud_north_01"
!
!    "sand_"         becomes   "sand_01",       "sand_02"
!    "sand_west"     becomes   "sand_west_01",  "sand_west_02"
!    "sand_east"     becomes   "sand_east_01",  "sand_east_02"
!    "sand_south"    becomes   "sand_south_01", "sand_south_02"
!    "sand_north"    becomes   "sand_north_01", "sand_north_02"

Many thanks to Do-Seong Byun for ​bringing this to my attention.
