Yá na década de 1970 los científicos de la [[NASA]] entamaron a sospechar la esistencia en Ganimedes d'un océanu perprofundu encerráu ente dos capas de xelu, una superficial y otra que envuelve, en contactu directu con elli, el mantu rocosu<ref name="Showman1999" /><ref name="clubsandwich 2014" />{<ref name="Sohl2002" /><ref name="Freeman2006">{{cite journal |last=Freeman |first=J. |title=Non-Newtonian stagnant lid convection and the thermal evolution of Ganymede and Callisto |journal=Planetary and Space Science |date=2006 |volume=54 |issue=1 |pages=2–14 |doi=10.1016/j.pss.2005.10.003 |url=http://bowfell.geol.ucl.ac.uk/~lidunka/EPSS-papers/pete2.pdf |archiveurl=https://web.archive.org/web/20070824155106/http://bowfell.geol.ucl.ac.uk/~lidunka/EPSS-papers/pete2.pdf |archivedate=2007-08-24 |format=PDF |bibcode=2006P&SS...54....2F }}</ref><ref name="amount of water in ocean">{{cite web | url=http://earthsky.org/space/underground-ocean-on-jupiters-largest-moon | title=Underground ocean on Jupiter's largest moon | publisher=EarthSky | date=March 15, 2015 | accessdate=
