     Notes on tags used in MITgcmUV
     ==============================
 
+o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean 
+  and trend from exf forcing and ctrl control adjustments
+o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
+  (since checkpoint57x_post)
+o change the default rotation period to 86164.s = the Earth rotation
+o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
+  and based on a reference stratification. Tested within hs94.cs-32x32x5.
+o seaice advection: add code for choosing between the default (2nd order
+  central differences) and multiDim advection schemes provided by
+  pkg/generic_advdiff
+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 default advection and diffusion
+    (turn on with SEAICEuseFluxForm)
+  - replace 1 in 3d global fields by kSurface in growth.F
+  
+checkpoint58a_post
+o seaice:
+  - bug fix in advect.F
+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.

           + 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
