Bunsen solubility coefficients for methane in distilled water
and in seawater at three salinities were determined with an
estimated accuracy of 0.5 YO. The experimental data were
fit by the least-squares method to an equation established
by Weiss. A table of Bunsen solubility coefficients covering
the temperature range -2' to 3OoC and the salinity range
0-40 parts per thousand was calculated from the fitted
equation. For seawater of salinity 34%0, the Bunsen
coefficients ranged from 0.04489 at O°C to 0.02368 at
3OoC. Solubility values for distilled water were in agreement
with those reported by Bunsen and Claussen and Polglase
but were 34% higher than those of Winkler and Morrison
and Billet
