RTOFS is showing a salinity drift (bias). This can be caused by HYCOM or NCODA or one exacerbated by the other.

RTOFS - modify archv_inc to use layers
NCODA (3Dvar) - create layers for restart

Simulation paraB will test these changes

Stopped paraB. New codes for NCODA implemented will use ADT option for ssh.
This run is called paraD.

Alternately this is a HYCOM layer thickness problem (the cause instead of the symptom).
Restarted paraD with another update for NCODA.

Stopped paraD because of failure on 20230501 in the Sulu Sea (near Philippines). More analysis is needed of what was the cause of this. Also will need more/better diagnostics of the run to foresee if the run is starting to show tendencies of this condition.
