On Vitubia those would be the main source of biotic oxygen, but Despina has much smaller bodies of liquid water comparatively, so I guess landed autotrophs would have a bigger role.
Makes sense re: the tidal heating. The residents have enough to deal with without massive amounts of volcanism anyway desu.
Unrelated, but you can get some really intense auroras in SpaceEngine if you mess around with the planet editor settings. These extend to over 1000 km in altitude.
