Mars Arabia and Deuteronilus Paleoshoreline Elevation and Offset Data

Mars data supports the analysis of hypothesized ancient ocean shorelines, specifically the Arabia and Deuteronilus levels. The dataset contains digitized, mapped, and calculated data for these putative paleoshorelines, including elevation profiles and lateral offset distances. It includes ArcGIS-ready files, CSV data, and analysis code from the associated research paper.

Use Cases

• Geospatial mapping of hypothesized Martian paleoshorelines using provided ArcGIS layer packs.
• Analyzing topographic consistency and lateral offsets of the Arabia and Deuteronilus levels based on elevation CSV files.
• Comparing newly mapped shoreline data with previous geological maps, such as the Tanaka et al. 2014 unit map.
• Reproducing figures and analyses from the Sholes et al. (2021) study using the included code and offset data.

Strengths

• Includes both raw and derived data types: original digitized shorelines, calculated lateral offsets, and analysis code.
• Data is structured for direct use in professional GIS software (ArcGIS-ready), facilitating geospatial analysis.
• Associated with a peer-reviewed publication (Sholes et al., 2021, Journal of Geophysical Research: Planets), indicating academic rigor.

Limitations

• Key metadata such as row count, file size, and specific column names are not provided in any source.
• Sources show a conflict on the publication year of the associated paper (2020 vs. 2021).
• The 'Last updated' field is consistently listed as 'None' or 'unknown', making freshness difficult to assess.
