Oceanography on Saturn´s moon, Titan

Saturn´s frigid moon Titan was long suspected to have seas of liquid methane and ethane: the existence and extent of these seas has been determined by the Cassini spacecraft, and sea state, depth and the physical properties of the liquid are being learned. Titan´s meteorology leads to concentration of liquid in the polar regions: two major northern seas, Kraken and Ligeia, and one shallow lake in the south, Ontario Lacus, are particularly well-studied to date. Titan serves as a new laboratory for physical oceanography, with familiar processes occurring under very alien conditions.
