Characteristics of the Basal Interface of the Martian South Polar Layered Deposits

Geospatial data on the basal interface of the Martian South Polar Layered Deposits (SPLD) derived from MARSIS radar data. The repository contains point and map data including elevation, thickness, time delay, and brightness measurements. It was created by Aditya Khuller and Jeffrey Plaut in 2021.

Use Cases

• Model the subsurface topography of the Martian South Pole based on elevation and thickness data.
• Analyze radar signal properties of the SPLD based on brightness and time delay measurements.
• Create interpolated maps of ice deposit thickness for regional geological studies.
• Study the relationship between surface and basal interface properties using the provided elevation and brightness fields.

Strengths

• Data is derived from the MARSIS instrument, a primary scientific radar on Mars.
• Includes both raw point data and interpolated map products for analysis at different scales.
• Provides multiple data products (elevation, thickness, brightness) for a multi-faceted analysis of the same region.

Limitations

• Column-level documentation is absent for some files; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale statistical modeling.
• Last update date is unknown; freshness unverified.

Provenance

Source

MARSIS (Mars Advanced Radar for Subsurface and Ionosphere Sounding) instrument data.

Collection Method

Radar data processing and interpolation, as described by Khuller and Plaut (2021).
