Using MARSIS signal attenuation to assess the presence of South Polar Layered Deposit subglacial brines

MARSIS attenuation and thermal data confirm that liquid brines are the most plausible source for the bright reflections at the base of the South Polar Layered Deposits. Such results also justify why SHARAD does not penetrate to the base of the ice.
