How would sea currents behave on a tidaly locked natural satellite with continuous water mass and dispers land mass (like our Earth) that orbited (let's say) a gass giant?

Answer 1

There are two possible answers depending upon the rotation and orbit of the satellite and if the satellite rotated as earth does to our sun. If the orbit was circular, then there might not be any tidal motion at all assuming the iron core of the satellite were also circular in mass and had a relative proportion to the gravity exerted upon it by the mother planet. However, if the orbit were other than circular, or if the satellite faced the parent planet with a singular facing, then tides would probably behave the same way our moon's gravity affects our oceans. But of course in a reverse type of effect.
