     Notes on tags used in MITgcmUV
     ==============================
 
 o seaice: 
+  - modify advection so that it works also on the C-grid
+  - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes 
+    problem in multi-tile runs with C-grid
+  - remove velocity clipping from seaice_dynsolver with C-grid
+  - fix drag (ocean on ice) formulation and a bug that caused noise in the
+    C-grid solver
+  - added a few comments to seaice_diffusion.F
+  - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
+    are now exclusive)
+  - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which 
+    required re-ordering the code a little:
+   + make DAIRN global variable (defined in SEAICE)
+   + move computation of the viscosities eta and zeta into a new separate
+     routine (because I need to recompute them in seaice_ocean_stress.F)
+
+checkpoint58b_post
+o AIM+thSIce: fix sign of Short-Wave through the Ice ; 
+  update output.txt of exp. aim.5l_cs.thSI
+o various mnc cleanups and improvements:
+  + shrink lookup tables by factor of ~4
+  + better error reporting when running out of lookup space
+  + able to handle longer path/file names (up to 500 chars)
+o adjoint:
+  - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
+  - TBD: "hidden" mom_vecinv recomp. in dynamics
+o change forcing_In_AB to affects both T,S forcing and Momentum forcing
+ (allow to differentiate between forcing components using new integer flags:
+  momForcingOutAB=1/0 & tracForcingOutAB=1/0)
+ and add new flag to put Dissipation tendency out of Adams-Bashforth.
+o ecco
+  - enable trend removal from SSH anomaly obs.
+o adjoint
+  - a fix for PmEpR when #undef EXACT_CONSERV
+  - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
+  - try to fix "hidden" recomp. in forward_step for NLFS
+    (NLFS seems broken sometimes after I checked it in)
+o seaice: 
  - add c-grid version of the dynamic solver:
    + three new routines that are the c-grid substitute lsr, dynsolver
      and ostres
