     Sites of cryovolcanisms on the surface, where this ammonia and water mixture reaches the surface, are possible locations for life that lives in liquid water but can tolerate ammonia.

   • 2015 March 12, John Timmer, “Jupiter’s moon Ganymede has a salty subsurface ocean, too”, in Ars Technica:

     Possible explanations include floods of liquid water, ice-based volcanic activity (termed cryovolcanism), or even some form of tectonic system.

     […] Voyager also found evidence of cryovolcanism on Neptune's moon Triton.
