Composition, seasonal change, and bathymetry of Ligeia Mare, Titan, derived from its microwave thermal emission

Lorenz, R. D.; Karatekin, O.; Janssen, M. A. +8 more

For the last decade, the passive radiometer incorporated in the Cassini RADAR has recorded the 2.2 cm wavelength thermal emission from Titan's seas. In this paper, we analyze the radiometry observations collected from February 2007 to January 2015 over one of these seas, Ligeia Mare, with the goal of providing constraints on its composition, bathy…

Vortices in Saturn's Northern Hemisphere (2008-2015) observed by Cassini ISS

West, Robert A.; Porco, Carolyn C.; Baines, Kevin H. +12 more

We use observations from the Imaging Science Subsystem on Cassini to create maps of Saturn's Northern Hemisphere (NH) from 2008 to 2015, a time period including a seasonal transition (i.e., spring equinox in 2009) and the 2010 giant storm. The processed maps are used to investigate vortices in the NH during the period of 2008-2015. All recorded vo…
