While many previously proposed enceladus plume transport models rely on a sharp liquid/gas boiling interface most forms of terrestrial explosive silicate volcanism a potential analog exhibit continuous exsolution/degassing and expansion of dissolved volatile bubbles during ascent within an open conduit. The team proposes to advance the multi-component multi-phase compressible plume transport model "cryo-erupt." advancing this model and determining if model predictions are consistent with existing enceladus observations represents an important contribution for two primary reasons: 1) the growing interest in directly sampling erupted or erupting materials for future missions to enceladus 2) the under-explored nature of this class of plume transport model which our preliminary work suggests is valid and stable on long timescales. If consistent with enceladus observations the cryo-erupt model fundamentally changes our understanding of how the enceladus plume erupts and has implications for relating plume observations to ocean composition.
