Table 5.

Environmental parameters reported for the samples in the introductory table by Schmidt (1912).

Column name in publication	Units as reported in publication	Notes
Weather		General meteorological conditions (cloudy, misty, clear etc.) are reported, but seem to be subjective, no scale of reference is reported anywhere.
Wind Direction0–12	Indicated in the column header as a 0–12 scale, but quadrants are reported (e.g. NNE; S)	0–12 is an unusual scale (commonly, degrees are used) and not used in the actual data. No further information available, maybe simply a typographic error in the column name.
Wind Force 0–12		Appears to be on a Beaufort scale, even if not specified in the original document.
Sea Direction0–12	Indicated to be on a 0–12 scale, but quadrants are reported (e.g. NNE; S).	Seems to be the observed direction of the swell, no further information given in the manuscript.
Sea Force0–12		Appears to be on a Beaufort scale, even if not specified in the manuscript(s) (The Douglas scale would have only 10 possible values).
Temperature Air	°C	Precision of one decimal place. Measurement device was not specified.
Temperature Surface	°C	Precision of two decimal places; given in the form of "12°40" in the manuscript.
Surface Chlorine	‰	Chlorine weight in grams per 1,000 g sea-water, unit specification from Nielsen (1912).
Surface Salinity	‰	Obtained by titration in the Mediterranean Sea and by aerometer in Bosphorus and the Dardanelles. Salinity weight in grams per 1,000 g sea-water Nielsen (1912).
