     Notes on tags used in MITgcmUV
     ==============================
 
+o seaice:
+  - removed all references to SEAICE_GRID.h fields from 
+    dynsolver, advect, diffus, lsr, without changing the results of lab_sea
+    (cubed-sphere configuration will change a little)
+  - grid computations in seaice_init are obsolete now.
+  - cleaned up code a little so that is easier to read (hopefully).
+  - added new (better?) discretizations of advection and diffusion
+    (still commented out)
+

+o shelfice: 
+  - separate shelfice load anomaly from pload (breaks with time 
+    dependent forcing), => introduce constant field shelficeLoadAnomaly.
+    Its default is 0., but it may be computed more cleverly from (unknown)
+    t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
+    done offline. A good approximation of the pressure load anomaly is
+    necessary to avoid large initial adjustment processes underneath 
+    deep-reaching shelfice.
+  - small fix in ISOMIP shelfice_thermodynamics
+  - add more sophisticated thermodynamics of Hellmer (1989), this is 
+    now the default
+  - give a few constants more intuitive names
+o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
+  if bulk formulae are used in long integration (especially EmPmR). Turn
+  on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
+  if balancePrintMean, the imbalance that is substracted is printed to
+  STDOUT.
+o fix bug (typo) in obcs_apply_eta.F
+o add a new package shelfice which enables us to model the circulation
+  underneath shelf-ice with draughts of hundreds of meters.
+ - works
+ - to do: + include improved thermodynamics
+          + check whether kSurfC (from model/inc/SURFACE.h) can be used
+            instead of new field kTopC
+          + can we use topoFile, Ro_surf and existing code in ini_depth.F 
+            instead of new field R_shelfIce and new code in ini_depth.F
+            and ini_mask_etc.F?
+          + adjust vertical mixing schemes?
+o seaice pkg: 
+ - add a cpp-flag to include a simple formula for a salinity dependent 
+   freezing point of sea water at the surface
+ - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
+   meridional stresses are now different (and hopefully correct)
+o AIM pkg: change threshold on large-scale condensation to conserve Heat.
+   update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
+   and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
+o pkg/diagnostics: add options and parameters for regional-statistics 
+   diagnostics ; define regions by reading a region-mask from a file 
+   (might add other options later)
+o pkg/bulk_force:
+ - add option and parameters to use AIM surface-flux formulae.
+ - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
+   others forcing fields (defined in PARM05, parameter file "data") are loaded 
+   from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
+ - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F 
+ - use the right EXCH call for uwind,vwind (to work on CS-grid).
+ - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
+   and parameters (note: calcWindStress replaces .NOT.readwindstress).
+ - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
+
+checkpoint58
 o add "--embed-source" option to genmake2 which, when the supporting 
   tools can be compiled (as determined by genmake2) will turn on the 
   embed_files package which then embeds the entire MITgcm source code
