Table entries are sorted according to reliability of the data, listing the most reliable type first: L) literature review, M) measured, V) VP/AS = vapor pressure/aqueous solubility, R) recalculation, T) thermodynamical calculation, X) original paper not available, C) citation, Q) QSPR, E) estimate, ?) unknown, W) wrong. See Section 3.1 of Sander (2015) for further details.


9) Value at T = 293 K.
64) The value is from Table 1 of the paper. However, J. Geophys. Res. forgot to print the tables and I received them directly from the author.
65) Fickert (1998) extracted a value from wetted-wall flow tube experiments. However, it was later discovered that under the experimental conditions no evaluation of Hs is possible (J. Crowley, pers. comm., 1999).
