The stabilisation of the gridded profiles in the WGHC climatology was done assuming that it 
is mostly errors in salinity which are responsible for the instability. For each unstable pair of 
gridded levels, salinities of upper/lower levels were decreased/increased iteratively until the 
stability of the pair was achieved (an increment of 0.00001 PSS was used). The procedure 
starts with the uppermost unstable pair and is repeated until the stability of the whole profile 
is achieved. The procedure thus ’’spreads” the salinity error in the vertical reducing individual 
salinity corrections. We note that typical corrections are small (an order of 10" 4 ).
