Latest Publication: Dune Migration on Mars

Cardinale, M., Silvestro, S., Vaz, D.A., Michaels, T., Bourke, M.C., Komatsu, G., Marinangeli, L., (2016). Present-day aeolian activity in Herschel Crater, Mars. Icarus, 265, 139-148. This paper presents evidence for ripple and dune migration in Herschel Crater on Mars. We estimate an average dune migration of 0.8 m and a minimum ripple migration of 1.1 m in... Continue Reading →

Latest Publication: Martian winds

Jackson, D. W. T., M. C. Bourke, and T. A. G. Smyth (2015), The dune effect on sand-transporting winds on Mars, Nature Communications, 6, Article number: 8796, doi:10.1038/ncomms9796 (open access). There are no long-term meteorological stations that measure in situ wind patterns on Mars. As a consequence, we don’t know which way the winds blow... Continue Reading →
