     Notes on tags used in MITgcmUV
     ==============================
 
+o pkg/seaice: a first HSALT time stepping equation has been checked in
+o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
+  in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
+  without requiring DO-IF statements
+o pkg/thsice:
+  use continuous power-law function for partition of energy between lateral
+  melting/freezing and thinning/thickening ; old code using step function
+  still available with #undef THSICE_FRACEN_POWERLAW
+  update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
+o testreport: change AD testing : check against results/output_adm.txt
+  using same scripts as for forward test.
+
+checkpoint59g
+o adjoint testing: in preparation for changing testreport:
+  - output format: cost and grad written on separated lines
+  - ad output results in directory "results" (instead of "results_ad")
+o pkg/seaice: adding ice salinity HSALT as a prognostic variable
+o pkg/seaice: changes for using pkg/seaice with pkg/obcs
+o pkg/ecco: allow user defined cost function contributions 
+o testreport:
+  Allow to choose (per experiment) the list of tested output variables
+   and the main variable (used to issue a pass/FAIL ) ;
+  - for now, done by adding the specific list in file: [exp]/input/tr_checklist
+  - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
+  Also modify printing of summary:
+   a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
+   b) echo the list of tested variables in the individual summary.txt of
+      each experiment.
+o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
+  threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
+  (but still depend on the tile decompostion of the domain).
+o pkg/seaice: change a discretization detail to make the B-grid code 
+  "more symmetric". This change is likely to remove all "ridges/leads" that 
+  where quasi-aligned with the grid in B-grid solutions. It may also be 
+  the solution to the stress coupling issues with the B-grid.
+o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
+  remove .cvsignore from input dir. (since testreport no longer run here).
+o pkg/thsice:
+ - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
+ - fix reshaping of sea-ice just after advection:
+   melt all the ice only if ice-volume is too small.
+ - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
+   prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
+ and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
+o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
+  tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
+o define mass2rUnit & rUnit2mass as units conversion factor, used for surface 
+  forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
+  (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
+  and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
+  of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
+  -> update output.txt
+o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
+ this affects truncation error: -> update output.txt of exp:
+  global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
+  ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.

+checkpoint59f
 o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode) 
 o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in 
   a bounded range (in forward mode)
 o pkg/ecco, ctrl, autodiff and mom_common:
  internal parameter controls, completements of implementations
 o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
+o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
+  (not seem any difference in testing results).
 o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains 
    at face corners.
 o pkg/generic_advdiff:
