     Notes on tags used in MITgcmUV
     ==============================
 
+o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
+  scheme and the corresponding test case (under front_relax dir). For now,
+  only available with Skew-flux form and not yet tested in realistic set-up.
+  adjoint: store directives updated, but gradient checks deteriorated,
+  so maybe GM/Redi adjoint is now broken.
+o seaice adjoint
+  * add AREA, HEFF, HSNOW as control variable
+    (should not change lab_sea results)
+  * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
+o pkg/seaice:
+  * added computation of saltFlux in seaice_growth;
+    For time being, sea ice salinity is assumed constant
+    contribution of snow flooding to freshening of sea ice is neglected.
+    SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
+    defaults to 0.0 in order to maintain backward compatibility.
+    Typical values for SEAICE_salinity are 4 to 10 g/kg.
+  * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
+  * added SEAICE_availHeatFrac, which specifies fraction of surface level
+    heat content used to melt or grow ice
+  * commented out cap of HICE: it helps keep ice thinner
+  * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
+  * applied OBCS T/S mask to HEFFM sea ice mask

 o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
  for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
