Titan's seas have tiny waves, tidal currents.

A recent study using data from the Cassini spacecraft has provided new insights into the hydrocarbon oceans on Saturn's moon, Titan. The research reveals evidence of tidal activity in Titan's oceans and suggests that their compositions vary. The study used data from Cassini's Radio Science Subsystem to create a bistatic radar system, which provided detailed information about the oceans. The findings also indicate that the rivers feeding the seas are primarily composed of methane until they mix with the ethane-rich open seas. Additionally, the study found that the seas have small surface waves, which may indicate the presence of tidal currents. This research provides valuable information for future missions and the potential exploration of Titan's seas. [Extracted from the article]
