3D Volumes of Shallow Radar (SHARAD) data

SHARAD 3D movie of Planum Boreum, the north polar cap of Mars

SHARAD 3D movie of Planum Australe, the south polar cap of Mars

The links above show movies of the latest version of the SHARAD 3D volumes, created in 2016. These fully imaged 3D volumes of the interiors of Planum Boreum and Planum Australe include SHARAD observations from 2311 MRO orbital passes in the north and 2093 passes in the south. The volumes reveal the interior stratigraphy and structure of the polar layered deposits and underlying materials. Depth-converted volumes assume water-ice dielectric of 3.15 in the subsurface.

We began with the northern volume, for which we carried out several iterations of the volume, each successive one using more data and improved processing methods. Using what we learned in that first effort, we were able to produce a complete volume for the south much more quickly. Arrangements for archival of these volumes in NASA's Planetary Data System are underway. In the meantime, we are providing the movies and a few snapshot views here.

A big thanks goes to SeisWare for their support of our work. All views shown here were created using their software, including the movies made with their 3D visualization tool. The production of SHARAD 3D volumes of the Martian polar terrains is funded by NASA's Mars Data Analysis Program.

2016 Planum Boreum 3D depth volume

This volume using 2311 orbit passes was first presented by Nathaniel Putzig at the 22nd Annual 3D Seismic Symposium on March 3, 2016 and is featured in the January 2017 volume of SEG's The Leading Edge (Foss et al., 2017; PDF available here). Foss and Putzig were interviewed by SEG in conjunction with this publication. Listen to the podcast here.
