Martian dunes indicative of wind regime shift in line with end of ice age.

ABSTRACT: Orbital observations suggest that Mars underwent a recent 'ice age' (roughly 0.4-2.1 million years ago), during which a latitude-dependent ice-dust mantle (LDM)^1,2 was emplaced. A subsequent decrease in obliquity amplitude resulted in the emergence of an 'interglacial period'^1,3 during which the lowermost latitude LDM ice^4-6 was etched and removed, returning it to the polar cap. These observations are consistent with polar cap stratigraphy^1,7, but lower- to mid-latitude in situ surface observations in support of a glacial-interglacial transition that can be reconciled with mesoscale and global atmospheric circulation models⁸ is lacking. Here we present a suite of measurements obtained by the Zhurong rover during its traverse across the
