Simulating Water-Rock Reactions on the Ocean Floor of Enceladus [#1074]
We have used a novel Enceladus simulant and an ocean fluid to experimentally simulate the water-rock interactions occurring on the ocean floor of Enceladus.

2:40 PM

3:30 PM

Lesage E.* Howell S. M. Naseem M. Miller J. W. Villette J. et al.

Chemical Composition of Erupted Brines on Europa [#1864]
We numerically model the coupled chemical evolution and pressurization of freezing brines in Europa’s ice shell to predict the composition of erupted cryolava.

Fifer L. M.* Toner J. D. Catling D. C.

Gas Loss from Enceladus' Ocean Due to Long-Term Plume Eruption [#1740]
Enceladus’ erupting plumes indicate that the ocean may be gas-rich, with a comet-like composition. But there is a missing methane problem — where did it go?
