Session Introduction
8:25 AM
Paladino T. G.* Nawotniak S. E. K. Kerber L. Millour E. Karunatillake S.
Ancient Volcanism May Have Influenced Patterns of Hydrated Regolith on Mars [#2431]
Unknown hydration / Explosive volcanoes rage / Could they be the key?
8:35 AM
Hamid S. S.* Kerber L. Clarke A. B.
Volcanic Degassing a Potential Source of Surface Water Ice Near Martian Volcanoes [#2890]
Volcanic degassing may have covered volcanic regions in water ice that later served as a source of ice for volcano-ice or impactor-ice interactions on Mars.
8:45 AM
Voigt J. R. C.* Hamilton C. W. Steinbrügge G. Christoffersen M. S. Nerozzi S. et al.
Revealing Elysium Planitia's Young Geologic History: Constraining Lava Emplacement Styles, Areas, and Volumes [#1638]
We reconstruct Elysium Planitia’s history using CTX to constrain lava flow areas, SHARAD for flow thicknesses, and derive lava volumes combining these results.
8:55 AM
Michalski J. R.* Rogers A. D. Edwards C. S. Cowart A. Xiao L.
Diverse Volcanism and Volcanotectonics Associated with the Eridania Basin on Mars [#1139]
The Eridania region contains volcanic domes, stratovolcanoes, pyroclastic shields and calderas, some with felsic compositions.
9:05 AM
Panel Q&A
9:25 AM
Farrand W. H.* Edwards C. S. Bhattacharya S. Tai Udovicic C. J.
Imaging Spectrometer Analysis of the Potential Hydration of Lunar Volcanic Areas [#1677]
Using several thermal correction approaches, M3 and IIRS data over lunar pyroclastic areas and areas of silicic volcanism are examined for signs of hydration.
9:35 AM
Stopar J. D.* Vannier H. Gaddis L. R. Ivey K. Horgan B. et al.
Compositional Diversity of Pyroclastics in J. Herschel Crater and Around Lavoisier Crater [#1587]
J. Herschel DMDs are uniform in composition; Lavoisier area deposits are diverse. Glassy-crystalline DMDs imply a spectrum of mild to moderate eruptions in FFCs.
9:45 AM
Moitra P.* Mallik A. Barnes J. J. Andrews-Hanna J. C.
Effects of C-O-H Degassing and Bubble Growth on Explosive Lunar Volcanic Eruptions Eruptions [#2621]
Understanding the effects of C-O-H volatile degassing and subsequent bubble growth on the explosivity of lunar volcanic eruptions.
9:55 AM
Sakimoto S. E. H. Gregg T. K. P.*
Tycho Crater Lunar Impact Melt Emplacement: COMSOL Modeling of Flow, Folding, and Cooling [#2587]
Impact flings fluid / Flows buckle over the bumps / Frozen reminders.
10:05 AM
Panel Q&A
10:25 AM
Rabinovitch J.* Scamardella J. Mitchell K. L.
A Proposed Cryovolcanic Eruption Mechanism for the Enceladus Plume [#2653]
Enceladus plume / A taste of the deep ocean / But how much is lost?
10:35 AM
Regensburger P. V.* Dufek J. Paty C. S.
Characterizing Cryovolcanic Conduit Conditions on Enceladus Using Multiphase Modeling [#2897]
Jets or effusive? / What conditions lie below / The icy surface?

Davies A. G.* Wilson L. Head J. W. de Kleer K. de Pater I.
Discharge Rate and Composition Controls on Thermal Emission From Voluminous Lava Flow Emplacement on Io [#1728]
Modeling of voluminous lava flows shows a brief eruption from a long fissure reproduces the thermal emission evolution from an “outburst” seen on Io in 2013.
10:55 AM
Mahieux A.* Goldstein D. B. Varghese P. V. Trafton L. M.
Remote and In Situ Observation of Plumes from Spacecraft on Airless Bodies such as Europa, Enceladus, or Io. What Can We Learn About the Ground Conditions by Using DSMC Simulations? [#1906]
This work presents DSMC simulations to study remote sensing and in situ observations of water plumes and constrain ground conditions.
