Code:
- disabled "safety checks" in ALE code

New diagnostics:
- MLD_003
- subML_N2
- neutral_slope_x/y
- split-up of surface fluxes

Answer change:
- Update MOM6z_SIS2_025 to C-grid coupling + levitation (not MOM6z_SIS_025)

Code changes:
- Moved de-allocation of fluxes (forcing_type) into MOM_forcing_type.F90

Non-code:
- Split diag_tables into components for use in XMLs

Bug fixes:
- Fix division by zero on land when restarting different mask_table restart

Configuration changes:
- Initialize sea-ice from spun-up CORE forced run. Data from /archive/Bonnie.Samuels/tikal_201403_mom6_2014.04.03/MOM6z_SIS_025_base_line/gfdl.ncrc2-intel-prod/restart/19040101.tar
- Levitate sea-ice

Answer changes for MOM6_SIS2_025:
- Refactor of tri-diagonal solver

Added example MOM6z_SIS2_025
- SIS2 using SIS1 transport

Answer changes:
- Fix uninitialized variable in salt redistribution.
- Distribute negative surface salt flux.
- Increased accuracy of vertical remapping to third order, PPM_H4.

Code changes:
- Extensive OpenMP updates.
- Optimization of "from z" initialization to work on high PE counts.
- Removed ppoly type in ALE (for OpenMP).

Bug fixes:
- Initialized of present_in_slope_v.

Non-code:
- Reduced length of tests for high PE counts.

Answer changes:
- Fixed negative salinity under point-river sources (remapping boundary condition error)
- Corrected tidal amplitude data & tuning
- Enabled the BBL scheme (disabled previously while debugging)
- Switched to the Sadourny enstrophy conserving scheme
- Added pressure dependence (linear) to Tfreeze
- Added five channel restrictions

Code changes:
- numerous OpenMP fixes
- updated to latest CVmix
- MLD diagnostic
- global SSS scalar diagnostic

Bug fixes:
- memory leak for transient mpp_domains
- OOB in remapping
- uninitialized index in tracer_registry
- increased length of path names

Non-code:
- revised and tested 1/4 degree grid generation scripts

This tag differs from dev/master/2014.01.17 only in using the modified coupler and shared code (post-tikal).

Fixed Arctic salinity bias

* Reduced coupled timestep from 2hrs to 1hr (avoids coupled instabilities)

Other answer changing commits:

* Parabolic shape profile in KPP non-local transport
* Cold-start sea-ice
* Turned off "reproduce_siena" flags
* Bicubic interpolation of winds (rather than bilinear)

Sea-ice initial conditions + turned off BBL-mixing

* Apprximate sea-ice initial conditions have been added to
  try to reduce the initial Arctic salinity drift
* Turned of BBL-driven mixing to avoid "cold spots"

Tikal-prerelease + mass weighting PG

o *Using mass-weighting fo T/S within pressure gradient calculation
o Switched to tikal-prerelease

Better salt-restoring data

o *KPP additive for single_column_z and MOM6z_SIS_025
o *New version of salt_restore.nc for MOM6z_SIS_025

*Fix for Arctic join + Kd diagnostics

o Moved Kd_interface diagnostic to before entrain_diffuse
  to diagnose true total Kd (in ALE)
o Removed ability to match KPP to interior diffusivity
o salt_restore.nc had bad data (moved old file to salt_restore_bad1.nc)
o seawifs_1998-2006_smoothed_2x.nc had similar issues
  (moved old data to seawifs_1998-2006_smoothed_2x_bad1.nc)

Reconfigured MOM6z_SIS_025 baseline setup

  o Turned off thickness diffusion
  o Turned off MLrad scheme
  o Turned off Gargett (N0 + N1)
  o Turned off diffuse_ML_to_interior
  o Turned off enhanced diffusion (convection)

For the first long test of the MOM6z_SIS_025 configuration
