  • The construction of Chasma Boreale on Mars 
    Holt, John W.; Fishbaugh, Kathryn E.; Byrne, S.; Christian, S.; Tanaka, K.; Russell, P. S.; Herkenhoff, K. E.; Safaeinili, A.; Putzig, N. E.; Phillips, R. J. (2010)
  • Dielectric properties of lava flows west of Ascraeus Mons, Mars 
    Carter, Lynn M.; Campbell, Bruce A.; Holt, John W.; Philips, Roger J.; Putzig, Nathaniel E.; Mattei, Stefania; Seu, Roberto; Okubo, Chris H.; Egan, Anthony F. (2009)
    The SHARAD instrument on the Mars Reconnaissance Orbiter detects subsurface interfaces beneath lava flow fields northwest of Ascraeus Mons. The interfaces occur in two locations; a northern flow that originates south of ...
  • Examination of gully sites on Mars with the shallow radar 
    Nunes, Daniel Cahn; Smrekar, Suzanne E.; Safaeinili, Ali; Holt, John W.; Phillips, Roger J.; Seu, Roberto; Campbell, Bruce A. (2010)
    Martian gullies, found on steep slopes along broad mid-latitudinal bands, have morphologies resembling those of water-carved gullies on Earth and have been dated to <10 Ma. As such, one of the leading hypotheses, though ...
  • Mars north polar deposits: Stratigraphy, age, and geodynamical response 
    Phillips, R. J.; Zuber, M. T.; Smrekar, S. E.; Mellon, M. T.; Head, J. W.; Tanaka, K. L.; Putzig, Nathaniel E.; Milkovich, S.

    Foss, Frederick J.; Putzig, Nathaniel E.; Campbell, Bruce A.; Levin, Stewart A.; Perry, Matthew R.; Holt, John W.; Christoffersen, Michael S.; Smith, Isaac B.; Morgan, Gareth A.; Russell, Aaron T. (2023)
    The Shallow Radar (SHARAD) instrument aboard Mars Reconnaissance Orbiter (MRO) has been conducting sounding operations of Mars' near surface for more than 16?years. Results of the SHARAD investigation have been well ...
  • SHARAD Soundings and Surface Roughness at Past, Present, and Proposed Landing Sites on Mars: Reflections at Phoenix may be Attributable to Deep Ground Ice 
    Putzig, Nathaniel E.; Philips, Roger J.; Campbell, Bruce A.; Mellon, Michael T.; Holt, John W.; Brothers, T. C. (2014)
  • Subsurface structure of Planum Boreum from Mars Reconnaissance Orbiter Shallow Radar soundings 
    Putzig, Nathaniel E.; Philips, Roger J.; Campbell, Bruce A.; Holt, John W.; Plaut, Jeffrey J.; Carter, Lynn M.; Egan, Anthony F.; Bernardini, F.; Safaeinili, Ali; Seu, Roberto (2009)
