Here we propose a new isostatic model minimizing crustal deviatoric stress and demonstrate that gravity and shape data predict a 38 4km thick ocean beneath a 23 4kmthick shell agreeing withbut independent oflibration data. Isostatic and tidal stresses are comparable in magnitude. South polar crust is only 7 4km thick, facilitating the opening of water conduits and enhancing tidal dissipation through stress concentration. Enceladus's resonant companion, Dione, is in a similar state of minimum stress isostasy. Its gravity and shape can be explained in terms of a 99 23km thick isostatic shell overlying a 65 +/- 30km thick global ocean, thus providing the first clear evidence for a present-day ocean within Dione.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Enceladus's and Dione's floating ice shells supported by minimum stress isostasy","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-02 01:31:45.286575","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Enceladus; Dione; isostasy; gravity; crust; subsurface ocean","OtherDescriptors":null,"Notes":null,"AnaPub":2016,"MonPub":null,"DateUpdate":"2017-06-02","DateCreate":"2017-05-16","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000386939800032","VABBcode":null,"OpenAcc":0,"DOI":"10.1002/2016GL070650"},"refs":null,"anarec":{"AnaID":285442,"PubliDate":2016,"Pagination":"10088-10096","XtraPublOfAnaID":null,"ISBN":null,"Volume":"43","Issue":"19","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42920,"SerRR":"Geophysical Research Letters.
