Europa ICONS is still funded and applications are open until 2/28 if you have interested undergrads! science.nasa.gov/planetary-sc...

Is there a published paper on this anywhere? I can find the AGU abstract but didn’t see a paper link for this topic.

But I still haven't ruled out incorporating C in other ways. Perhaps Europa accreted anhydrous rock and C-rich ices, and the ice melted and separated from the rocky interior before the fluid could equilibrate with its surroundings. More work to be done here.

If Europa Clipper does not provide strong evidence for seafloor volcanism, then I think this is consistent with Europa forming its ocean from hydrated silicates and tidal heating being concentrated in the ice. The former may lead to a C-rich ocean as Melwani-Daswani+ suggested. (3/n)

Based on my recent work (Trinh et al., 2023), we show that a metamorphic origin for Europa's ocean may suppress the warming of the interior, so volcanism is less likely (albeit not impossible). Tidal heating should help is learn more, but this is also poorly understood. (2/n)

I think Melwani-Daswani et al. (2021) provides a great argument for a C- and Cl-rich ocean if Europa accreted material similar to CM/CI chondrites. Right now I'm trying to explore other compositions not captured by meteorites with similar petrology models. (1/n)
