Registration via the link below is required in order to receive the zoom meeting invitation and/or access the recording, which will become available after the meeting. IAVCEI/IACS VIIC Seminar: Volcanoâ??Ice Interactions on Mars with Jim Head and Kat Scanlon 8th December, 2021 | 2p PDT | 5p EDT | 10p UTC | 12p HST 9th December, 2021 | 7a JST | Jim Head | Brown University | Volcanoâ??Ice Interactions on Mars: Keys to Geologic and Atmospheric History The current Mars ambient climate is a hypothermal, hyperarid desert with kilometers-thick accumulations of water ice at the poles. Geologically recent obliquity changes have transported significant quantities of ice equatorward to form glaciers of various types. The nature of the ancient ambient climate of Mars is currently debated (Is it â??warm and wetâ?? or â??cold and icyâ???). All of these characteristics provide abundant opportunities to study volcano-ice interactions. Following a brief introduction to Mars environmental and volcanological histories, we will present several examples (volcanic edifices built under polar ice sheets, geothermal heating of volcano summit ice, top-down melting of ice sheets by lava flows, mega-lahars, dikes now exposed in former ice sheets, etc.). These illustrate how volcano-ice interaction analysis has helped to improve our understanding of Marsâ?? volcanic and climate histories and their interrelationships. Kat Scanlon | Brown University | Volcanoâ??Ice Interactions in The Tharsis Montes Glacial Deposits, Mars Orographic lifting by the three enormous Tharsis Montes volcanoes on Mars resulted in glaciation on their windward flanks as recently as ~125 million years ago, coinciding with volcanic activity in the region. I will review previous work on volcano-ice interactions in the glacial deposits adjoining the Arsia Mons volcano, and discuss new high-resolution images and digital terrain models of the better-exposed hypothesized glaciovolcanic landforms adjoining the Pavonis Mons volcano. You are invited to a Zoom meeting.
