The phase-averaged wave model, SWAN, was applied within the Delft3D modeling system (Deltares, 2018) with reduced gravity and a range of atmospheric densities and wind speeds to simulate potential conditions that could generate wind waves on Mars. Purpose: Model simulations of wave development on an ancient lake on Mars were used in conjunction with analysis of sedimentary structures observed in imagery collected by the Mars rover Curiosity to explore the possibility that wind waves are strong enough to transport sand and form wave ripples. The presence of wave ripples would signify that ice-free liquid water was present on the surface of Mars in the past.

Logical_Consistency_Report: All data fall within expected ranges. Completeness_Report: Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.

Lineage: Process_Step: Process_Description: The phase-averaged wave model, SWAN, was applied within the Delft3D modeling system to simulate wave growth on a regular, curvilinear grid. The source code of SWAN (version 40.72ABCDE) was modified and recompiled to incorporate variable atmospheric density in the wave calculations. Process_Date: 20160714 Process_Step: Process_Description: A model grid and bathymetry were constructed with a lake basin that was 20 km wide and 10 m deep that sloped up to the shoreline over a distance of 120 m. The model grid contained 50 grid cells along the length of the lake that were spaced at 1.2 km intervals from the upwind coastline to 18 km downwind. Between 18 km and the shoreline, the grid spacing gradually decreased to as fine as 6.5 m to better resolve shallow-water processes. Wave development was simulated for 24 frequency bins between 0.05 and 1 Hz using 3rd generation physics and default values for bottom friction, white-capping, depth-induced breaking, and wind growth (Deltares, 2018). Process_Date: 20171221 Process_Step: Process_Description: Three sets of simulations were performed with atmospheric densities of 6, 60, and 600 mbar. For each atmospheric density, 5 wind speeds corresponding to 0.25, 0.5, 1, 2, and 4 times the threshold wind speed needed to initiate tranport of 125-micron sand grains on land were prescribed. See Rubin and others (2022) for details on how the threshold wind speeds were determined. Process_Date: 20210824 Process_Step: Process_Description: Results from all model simulations were tablulated and written to comma-separated text files for distribution.
