     Notes on tags used in MITgcmUV
     ==============================
 
+o pkg/seaice: 
+ - clean up the 3-time levels of UICE,VICE,HEFF,AREA in three steps:
+  1. introduce fields for time step (N-1)
+  2. do not use levels 2 and 3 anymore (but keep them)
+  3. replace 3D versions of UICE,VICE,HEFF,AREA by 2D versions. This 
+     includes changes to pkg/thsice/thsice_get_velocity.F, 
+     model/src/external_forcing_surf.F, pkg/obcs/obcs_apply_seaice.F, and
+     pkg/obcs/obcs_apply_uvice.F.
+ - completely remove code for leap-frog time stepping for second order
+   advection
+ - adjusted adjoint accordingly;
+   gradient checks have improved by an order of magnitude!
+ 
+checkpoint61q
+o pkg/seaice: fix bug in free slip boundary conditons for LSOR solver
+ - the boundary conditions along open boundaries are unclear, because the
+   associated masks are set to zero and are thus treated as closed when
+   applying the slip-boundary conditions.
+ - move initialisation of grid variables from seaice_init_varia to _fixed
+o adding doc/diags_changes.txt
+o model/src: 
+  do_the_model_io: rename few pkg S/R which are called from do_the_model_io, 
+   to avoid "_diags" naming if no relation to pkg/diagnostics.
+  ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF 
+   file and only call PLOT_FIELD_XYZ if debugMode=T.
+  remove few PLOT_FIELD_XY calls outside initialisation.
+  remove few unnecessary BARRIER.
+o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling
+  of salt_plume package in Southern Ocean 
+o pkg/thsice: 
+ - fix hOceMxL in overlap (needed for sea-ice advection); 
+   update output of experiment global_ocean.cs32x15.icedyn.
+o pkg/seaice: 
+ - make the (placeholder-)tracer IceAge a little more meaningful
+  by avoiding ridging of age due to convergent ice flow
+ - add diagnostics for surface temperature, atmospheric and oceanic
+   heat flux, and atmospheric and oceanic ice growth
+
+checkpoint61p
+o eesupp (global_max & global_sum):
+ - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
+ - remove starting & endding barrier (no longer needed)
+o pkg/mdsio, writelocal:
+   works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
+   (remove the STOP): uses shared buffer IO to store data from all threads
+   and then let master-thread write nThreads tiles.
 o pkg/mdsio (read/write field):
  - tiled IO done in 1 piece (all levels at a time);
+ - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
  - multi-threaded: allow to read/write local (non-shared) array
    (was already working with singleCpuIO ; now works also without);
    => no longer needs barrier call after reading a file (added inside
-   mds_read/write field). 
- - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
+   mds_read/write field).
  - move barrier calls outside gather/scatter_2d to mds_read/write_field
 o pkg/obcs/exf
   - exf_getffieldrec.F: add a few ". _d 0" and
