This folder contains the Supplementary Data files consisting of input data and output data products. The paper is accepted in Geophysical Research Letters. A preprint may be found here: https://doi.org/10.1002/essoar.10507048.1, but please see the article on Geophysical Research Letters for the properly formatted, peer-reviewed, revised version.

Contents:

AccretR Europa MC-Scale composition output.xlsx
Contains the composition of Europa after accretion, obtained by running the AccretR program. AccretR can be found on Zenodo: https://doi.org/10.5281/zenodo.3827540 or GitHub (most up to date): https://github.com/mmelwani/AccretR

Fe-S core composition models
Contains the Perple_X input and output files for constraining the composition of the Fe+-S core. Thermodynamic data used was from Saxena and Eriksson (2015), also included as a Perple_X thermodynamic file.

Rcrust prograde metamorphism models
Contains the input and output files for the Rcrust models, which are the metamorphic prograde path thermodynamic. Rcrust is required to run these models
(http://www.sun.ac.za/english/faculty/science/earthsciences/rcrust), as well as the "meemum" program from Perple_X (https://www.perplex.ethz.ch/). The Perple_X version used was "6.8.7", and was compiled from source to enable 12 thermodynamic components (i.e. major elements).

CHIM-XPT ocean column composition models
Contains the CHIM-XPT input and output files, which model the ocean composition from seafloor to surface, including precipitated minerals, aqueous solutes and saturated gases. Inputs for these models were the fluids extracted from the Rcrust prograde metamorphic models.

Density and volume of clathrates.xlsx
Shows the calculations carried out to find the temperature, density and volume of CO2 clathrates in Europa's ocean.
