Buch, Kurt published the artcileThe influence of temperature on pit determinations with color indicators, Quality Control of 596-01-0, the publication is Beret. 18th Skand. Naturforskermode (Copenhagen) (1929), 229-32, database is CAplus.

The buffer solution should preferably be brought to the temperature of sea water in situ but if Walbum’s correction tables are used this cannot be under 10°. The pH of a sample at t° is the pH at the buffer t + α(ta -tb). α from Walbum’s table: for α-naphthophthalein -0.0084, phenolphthalein -0.01, phenol red 0.01 and cresol red -0.0053. If the temperature has changed during the colorimetric readings also add α'(t’a – ta), α’ being 0.006 for α-naphthophthalein and 0.004 for phenol and cresol red. Phenolplithalein requires no correction.
