Rapid Impact Crater Relaxation Caused by An Insulating Methane Clathrate Crust on Titan: Data and Marc Files

Data files for several figures in the manuscript "Rapid Impact Crater Relaxation Caused by An Insulating Methane Clathrate Crust on Titan" Published in The Planetary Science Journal. This includes data for the following figures: 4, 6, 7, 8 and 10. Two example Hexagon Marc-Mentat mud files for the axisymmetric thermal simulation and mechanical simulation of a 10 km thick clathrate, 85 km diameter crater are also included.

Each column is self-explanatory except for the two relative depth data files. "Relative_Depth_Deep_Fig8" includes the results for simulations that use the initially deeper crater depth, and "Relative_Depth_Shallow_Fig8" includes the results for simulations that use the initially shallower crater depth. The columns are labeled with a shorthand notation for pairs of columns that represent the relative crater depth at specified times in the simulation. An example of time is “t(yr)_v21_120_5” and the corresponding relative depth column is “v21_Rd_120_5.” Time is given in years and relative depth is unitless. These specific examples provide results for a simulation that has a viscosity cutoff of 10^21 Pa s and a 120 km diameter crater with a 5 km thick methane clathrate crust overlying water ice.
