Looking at the Victoria dunefield it strongly resembles the patterns of sand grains on a vibrating tin lid. I have started to wonder if resonance could indeed be involved. Something along the lines of standing sound waves within the crater producing displacement nodes and antinodes that could cause very light particles to migrate to the nodes. Next question: given the dune wavelengths what would be the predominant frequencies of these sound waves? Would they be audible or infrasonic? At this point I realised I have no idea what the speed of sound is at Victoria. Any relevant facts or opinions to constrain my rambling thoughts would be most welcome. Likewise any pointers to previous discussion along these lines.
