Arabia Terra wind streaks extend many tens to a few hundred kilometers southeast or southwest and have been the subject of Mars geologic research since the early 1970s using image data from the Mariner 9 (Sagan et al, 1972(Sagan et al, , 1973Arvidson, 1974), Viking Orbiter, (Soderblom et al, 1978;Thomas and Veverka, 1979;Kieffer et al, 1981;Peterfreund, 1981;Thomas et al, 1981;Thomas et al, 1984;Thomas and Veverka, 1986;Henry and Zimbelman, 1988;Presley and Arvidson, 1988;Arvidson et al, 1989;Strickland, 1989), and Mars Global Surveyor (Mustard, 1997;Cooper and Mustard, 1998;Edgett and Malin, 2000;Pelkey et al, 2001;Wyatt et al, 2001) missions. A few wind streaks similar to those in Arabia Terra occur in neighboring Xanthe Terra; in the opposite hemisphere to Arabia Terra near Marte Vallis, Tartarus Colles, and Gale crater (Thomas et al, 1981;Peterfreund, 1981;Zimbelman, 1986); and in at least one crater in the circum-polar plains of Planum Boreum (Fig.…”
