Implications of the high D/H ratio for the sources of water in Venus' atmosphere
Observations of a water concentration of only 30 parts per million in Venus' atmosphere suggest that the residence time of water in the atmosphere, before it escapes to space, is short compared with the age if the solar system, which casts doubt on the primordial ocean hypothesis. The D/H ratio...

Summary: | Observations of a water concentration of only 30 parts per million in Venus' atmosphere suggest that the residence time of water in the atmosphere, before it escapes to space, is short compared with the age if the solar system, which casts doubt on the primordial ocean hypothesis. The D/H ratio of the planet's source water is discussed. |
