The Solubility of N2 in High-pressure Ice and Its Consequent Outgassing Limitations in Water Worlds
The Astrophysical JournalExoplanets with a few percent water mass fraction may host a high-pressure ice layer that separates the atmosphere from the interior. We investigate the role played by this layer in the transport of N _2 between the interior and the atmosphere.

Global scale observations of atmospheric molecular hydrogen and its stable isotopic composition [PDF]
, 2012 With average mixing ratios (χ) around 550 ppb (nmole/mole), molecular hydrogen (H2) is the most abundant reduced gas in our atmosphere after methane (CH4), but considerably less studied.
