     Notes on tags used in MITgcmUV
     ==============================
 
+o pkg/seaice:
+ - and new damping criterion for EVP solver according to Hunke, JCP, 2001
+ - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value). 
+   It is turned off by default (=-1.), because it changes the results.
+ - make it possible to read AREA from a file, too.
+
+checkpoint59c
+o add S/R and diagnostics for oceanic mixed-layer depth
+o move GMRedi call after all vertical mixing schemes (including KPP)
+o pkg/thsice: 
+ - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
+  (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
+o pkg/obcs:
+ - bug fix for balance code
+o pkg/seaice:
+  - allow values of SEAICE_elasticParm > 1
+  - add new parameter SEAICE_evpTauRelax as an alternative 
+    to SEAICE_elasticParm
+  - make lsr boundary conditions free slip (by default), changes result
+  - add code for no slip boundary conditions for lsr
+  - set minimum of zeta to zero (and not 4e8) (changes results)
+  - add a cap on AREA after advecting AREA if seaice_growth is not called
+o change calculation of Visbeck K:
+  - no longer depend on tapering scheme; instead, compute slope (limited 
+    by GM_maxSlope). this is equivalent to what was comuted before with
+    clipping or linear tappering.
+  - fix vertical averaging (wrong by 1/2 level)
+  - leave the old version (but will not be maintained) within
+    #ifdef OLD_VISBECK_CALC / #endif
+  - update output of exp. ideal_2D_oce
+o change error catch in calc_r_star to improve vectorization
+o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
+  add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
+o adjoint:
+  Re-organized adjoint checkpointing according to Matt Mazloff
+  (but with modifs/completions/cleanups)
+  Storing is now bundled into large arrays to optimized I/O
+  (and second step in cleanup of the_main_loop)
+
+checkpoint59b
+o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
+  - export/import (between ocean & coupler) fields needed for ocean DIC.
+o pkg/seaice: 
+  - get rid of three more exchanges seaice_calc_viscosities (required 
+    different loop boundaries in seaice_lsr and seaice_ocean_stress)
+  - bug fix in seaice_ocean_stress (update of lab_sea required)
+  - reduce loop boundaries to necessary minimum also in seaice_evp
+  - go back to the old way of computing deltaC/Z as the adjoint likes that 
+    better
+o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
+  passive tracer to an Age Tracer) + update output.txt
+o pkg/exf:
+  - implement A-grid / C-grid selection for wind-stress input files.
+  - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
+  for now, in exf_bulk_largeyeager04.F only :
+  - change implementation for case where windspeed + 2. components wind-stress
+    are read-in. AND use rhoConstFresh to convert evap.
+o pkg/seaice:
+  - use correct EXCH_UV for wind-forcing (on A-grid).
+  - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
+    SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
+o pkg/exf:
+  - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
+  EXF_INTERPOLATION: 
+  - merge global_with_exf/code version of exf_interp_read.F
+    to the main code ; 
+  - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when 
+    reading the file ; Important: This options needs to be defined to recover 
+    previous code.
+    otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
+  - no longer loose real*8 precision along the way when using exf_iprec=64.
 o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
   - change discretisation of evp-solver in order to avoid another exchange
     (changes lab_sea) and clean up a little
@@ -24,7 +95,7 @@
 o pkg/thsice:
  fix few little problems, in thsice_calc_thickn.F:
   - growth vertically (and not laterally) if iceFrac == iceMaskMax
-  - melt laterally only if hIce < hThinIce (as the comments say)
+  - melt only laterally if hIce < hThinIce (as the comments say)
   and in thsice_extend.F:
   - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
   - start to form ice as soon as the minimum ice-volume is reachable.
