     Notes on tags used in MITgcmUV
     ==============================
 
+o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
+  and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
+o gad_som : fix flux output (& diagnostics) to have same units as other   
+  advection scheme fluxes (was previously multiplied by deltaT).   
+o added verification/seaice_obcs both to test seaice open boundaries
+  and to provide an example matlab scrpt for generating them
+o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
+o pkg/salt_plume: clean up salt_plume_frac.F to
+  remove redundancy in PlumeMethod 1 and 4
+o pkg/kpp: added saltplume diagnostics
+o pkg/obcs and pkg/seaice:
+  - do not set uice and vice to zero when OB*icefile are unspecified
+  - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
+  - moved seaice tracer obcs after call to seaice_growth
+o pkg/salt_plume: added various options for salt plume depth
+  criterion and for vertical distribution of the salt
+
+checkpoint59l
+o pkg/ptracers: new version of ptracers pickup:
+  read meta file and write only fields which are needed to restart.
+  ( same logic as main pickup file ; also using pickupStrictlyMatch )
+o pkg/seaice:
+  - add timescale for melting due to warm mixed layer as a means of
+    setting SEAICE_availHeatFrac more conveniently
+  - add a CPP-flag/runtime parameter check for flooding algorithm
+  - reformulated availHeat in seaice_growth.F to be independent of AREA
+o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
+  unit changes
+o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
+o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
+  SX vector computer.
+o pkg/seaice:
+  - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
+    seaice forcing fields can now be read only through pkg/exf
+  - removed some unused halos
+o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
+o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
+  or U/VICE from U/VWIND before computing U/VSTRESS
+
+checkpoint59k
+o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
+  dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
+o fix un-initialised variable problem (in mom_vecinv & shap_filt):
+  all experiments pass when compile with un-initialised var. checking option.
+o added pkg/salt_plume
+o script to test restart (for now, in MITgcm_contrib/jmc_script)
+o pkg/seaice: new read/write pickup version. 
+  read meta file and write only fields which are needed to restart.
+  ( same logic as main pickup file ; also using pickupStrictlyMatch )
+o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
+o lab_sea.hb87: modify the domain & update output.hb87.txt :
+  lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
+  at j=1 & j=Ny+1 : this case is not treated correctly in the restart
+  process. Fixed here by closing the domain at the Northern boundary.
+o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
+o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
+  a set of consecutive levels in/from a 3-D array.
+o pkg/ptracers: 
+  use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
+  to-do: fix pkg/diagnostics when large number of diagnostics are defined.
+
+checkpoint59j
+o in pkgs: dic, obcs, offline, rbcs:
+  standard way to compute coeff. for time interpolation between 2 time reccords
+  which retains full precision (& make results less dependent on compiler).
+  update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
+o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
+  packages instead of reading ice cover and wind speed separately
+o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
+ (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
+  to allow to compile customized code before the update)
+o cleaning-up: 
+  - fix CPP instruction syntax in pkg/obcs
+  - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
+    add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
+  - fix some threads issue in IO parts.
+o pkg/dic:
+  - add tons of "_d 0" (--> much better testreports !)
+   and then update outputs of tutorial_global_oce_biogeo
+o pkg/mom_fluxform:
+  add a special version of momentum advection intended to conserve momentum
+  next to a bathymetry step or a coastline edge. (default = off = #undef)
+o new read/write pickup version:
+  - for now, only implemented for main (mdsio) pickup file.
+  - write out only what is needed to restart; merge pickup_nh , pickup_ph
+    and main pickup together.
+  - read meta file; read only what is needed to restart; stop if a field
+    is missing (if pickupStrictlyMatch=T, = the default) or try to restart
+    if it make sense (even if the restart is not perfect).
+  - if no meta file, assume that pickup to read corresponds exactly to
+    a pickup that would currently be written.
+  - read pickup written in the old format (until checkpoint59i) if it
+    recognizes an old meta file (no field-list).
+  - add a meta file in exp. which starts from a pickup: 2 cases:
+    a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
+     e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
+    b) a meta file describing the content of the associated pickup file
+     e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
+o pkg/mdsio & pkg/rw:
+  - new routine to read a meta file ; new set of routine to read
+    Multiple-fields file (with meta file).
+o added open boundary conditions capability for seaice
+    HSNOW, HSALT, UICE, and VICE
+
+checkpoint59i
+o adjoint:
+  * fix multiDimAdvection adjoint 
+    (partial recomputation problem by TAF for fVerT(:,:,kDown)
+    and comlev1 size definition (maxpass vs. max. number of tracers)
+  * verification/global_ocean.90x45x15 adjoint now tests
+    NLFS and multiDimAdvection using DST3 (=30)
+  * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
+o pkg/kpp: add "_d 0" to real constant (if missing); 
+  update output of exp: natl_box (10.digits); vermix (std, 7.digits)
+  and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
+o prepare for "clever pickup" implementation: add new header file "RESTART.h"
+  for internal parameters related to restart process (formerly from PARAMS.h)
+  and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
+o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
+  as argument. (only atm2d & obcs write_pickup have not yet been updated)
+o pkg/monitor:
+  - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
+  - fix mon_stats_rs (statistics over the full domain, even where field is zero)
+  - account for deep Atmosphere factor and density factor (anelastic)
+o added open boundary conditions capability for seaice HEFF and AREA
+o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
+  thermodynamics
+  - requires a little reorganization, which affects the testreport results 
+    of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
+    so that now the conservative form is tested
+  - add a few comments
+o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
+o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
+o add new diagnostics to seaice: advective, diffusive fluxes (only for
+  multidim-advection, for scheme 2 they are not filled) and transports, 
+  thermodynamic growth rates
+o change units of EmPmR (inside the code, + within coupling interface)
+  from m/s to kg/m2/s (mass flux) but leave input file unchanged.
+  Affects results @ truncation level (cg2d match) and update output of 
+   experiments: lab_sea(6), global_ocean.90x40x15(10),
+  global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
+  + adjoint results: global_ocean_ebm(11) and lab_sea (12).
+  Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
+  Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
+
+checkpoint59h
+o pkg/exf: 
+  - improve vectorization by moving if-statement out of loops in
+    exf_mapfields, exf_radiation
+  - exf_bulkformulae.F: introduce 2D fields and vectorize code
+o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
+o testreport: 
+  - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE 
+    monitor & update offline_exf_seaice exp. output.
+  - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
+o pkg/seaice:
+  - bug fix in the evp solver: boundary conditions were affected be
+    masking of zMax/zMin (changes results)
+  - minor bug fix in boundary conditions in seaice_calc_strainrates 
+    (changes results for no_slip)
+  - seaice_lsr.F: make interpolation of eta dependent on boundaries
+  - replace hardcoded lower limit for zeta (zMin) by runtime parameter
+  - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
+    stress formulation and no-slip boundary conditions
+o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
+  in gad_calc_rhs.F ; add few safety stops in initialisation phase.
+o pkg/seaice: a first HSALT time stepping equation has been checked in
+o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
+  in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
+  without requiring DO-IF statements
+o pkg/thsice:
+  use continuous power-law function for partition of energy between lateral
+  melting/freezing and thinning/thickening ; old code using step function
+  still available with #undef THSICE_FRACEN_POWERLAW
+  update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
+o testreport: change AD testing : check against results/output_adm.txt
+  using same scripts as for forward test.
+
+checkpoint59g
+o adjoint testing: in preparation for changing testreport:
+  - output format: cost and grad written on separated lines
+  - ad output results in directory "results" (instead of "results_ad")
 o pkg/seaice: adding ice salinity HSALT as a prognostic variable
 o pkg/seaice: changes for using pkg/seaice with pkg/obcs
