Data For: Where are Mars' Hypothesized Ocean Shorelines? Large Lateral and Topographic Offsets Between Different Versions of Paleoshoreline Maps.

Data used in the analysis of the Arabia and Deuteronilus Levels for Sholes et al. (2021) submitted to the Journal of Geophysical Research: Planets. 

Contains ArcGIS-ready data and CSV files for all digitized, mapped, and provided putative martian paleoshorelines analyzed in the paper. Also includes measured and calculated offset data, figures, and code used for analysis/plotting. 

See README for explanation of each directory/file. 

Figure1: Mapped levels are found in "Elevation Data" for both the Arabia and Deuteronilus Levels. Also in the ArcGIS layer pack file. 
Figure 2: Elevations of the mapped levels are in the "Elevation Data" folder for both levels and the open-basin deltas. Mapped and calculated lateral offset distances are found in the "Offset Data" folder. 
Figure 3: See the "Elevation Data/Arabia/4_Sholes2021_Arabia_Topo.csv" and "Elevation Data/Deuteronilus/0_Ivanov2017_Deuteronilus_Original_Topo.csv"
Figure 4: Mapped levels are found in "Elevation Data" for both the Arabia and Deuteronilus Levels. Also in the ArcGIS layer pack file. Mapped lateral offsets are found in the "Offset Data" folder for each level as well. 
Figure 5: Mapped levels are found in "Elevation Data" for both the Arabia and Deuteronilus Levels. Also in the ArcGIS layer pack file.
Figure 6: See the "Elevation Data/Deuteronilus/7_Sholes2021_Deuteronilus_Topo.csv" and "Elevation Data/Deuteronilus/0_Ivanov2017_Deuteronilus_Original_Topo.csv"
Figure S1: Mapped levels are found in "Elevation Data" for both the Arabia and Deuteronilus Levels. Also in the ArcGIS layer pack file. 
Figure S2: Mapped levels are found in "Elevation Data" for both the Arabia and Deuteronilus Levels. Also in the ArcGIS layer pack file. Geological units are from the Tanaka et al. 2014 map. 
Figure S3: Mapped levels are found in "Elevation Data" for both the Arabia and Deuteronilus Levels. Also in the ArcGIS layer pack file. Mapped lateral offsets are found in the "Offset Data" folder for each level as well. 
Figure S4: Mapped levels are found in "Elevation Data" for both the Arabia and Deuteronilus Levels. Also in the ArcGIS layer pack file. Mapped lateral offsets are found in the "Offset Data" folder for each level as well.
