Is the underground sea on Titan formed of water or hydrocarbons. Is anyone certain?
I have read a lot of various documents from NASA and Cassini missions and Huygens missions, and I have become confused.

Titan is believed to have a layer of liquid water under its surface, due to tidal heating of the icy crust.
Titan has a surface formed of ices with some hydrocarbon (methane) lakes. The crust of Titan is mostly water ice. Below this, there is a liquid water layer and perhaps more ice and silicate rocks below that.
