Composition, seasonal change and bathymetry of Ligeia Mare, Titan, derived from its 2.2-cm thermal emission

Ligeia Mare is the second largest sea of Saturn's moon Titan. It is also the first extraterritorial sea for which a bathymetry profile was obtained. In this paper, we analyze all data acquired up to July 2013 in the passive mode of the RADAR (i.e., radiometry mode) on board the Cassini probe in order to constrain its composition, seasonal change and bathymetry.
