===Interfacial liquid layers model===
Another model for these southern hemisphere features involves ULI water (undercooled liquid water) which forms as a thin layer over surfaces and can
The idea then is that this ULI water would be the water source for liquid brines which then flow down the surface to form the features. ULI water can also be used by microbes directly - and although the conditions would be cold for Earth microbes, perhaps Martian microbes could use it at lower temperatures. <ref name=MöhlmannULIbiorelevant>Möhlmann, D.T., 2009.

▲Another model for these southern hemisphere features involves ULI water (undercooled liquid water) which forms as a thin layer over surfaces and can melt at well below the usual melting point of ice. In Mohlmann's sandwich model, then the interfacial water layer forms on the surfaces of solar heated grains in the ice, which then flows together down the slope. Calculations of downward flow of water shows that several litres a day of water could be supplied to the seepage flows in this way.<ref name="MartínezRenno2013DarkDuneSpots">{{cite journal|last1=Martínez|first1=G.
