Geophys. Res. Space Physics. (Accepted) Key Points: - Enceladus-origin OH+, H2O+, and H3O+ dissociate within 5-10 Saturn radii, leaving O+ and H+ dominant. - Ionosphere-plasma coupling is strongest at 5-10 Saturn radii, where flow speeds reach about 80% of rigid corotation. - O+ ions make up nearly 70% of Saturn’s thermal plasma population across the 25 magnetosphere out to 16 Saturn radii.
