The oil was observed to spread in a thin layer on the under-surface of the gas bubble. When the sheet was thawed, the gas was observed to escape when the minimum temperature in the ice sheet rose to -3.6°C, and this caused the release of a few drops of oil. The bulk of the oil, however, emerged at the same time as a pure oil spill in a control experiment. It is concluded that the presence of gas greatly increases the area over which spilled oil will surface, but does not affect the timing of its appearance"--Abstract.
