Dear Colleagues, This is a gentle reminder of the upcoming deadline (July 31st) to submit abstracts to our AGU24 session, V018: Origin, Distribution, and Transport of Volatiles in Earth and Terrestrial Planets in the section Volcanology, Geochemistry, and Petrology. We encourage abstract submissions from early-career scientists and underrepresented communities. The link to our session: https://urldefense.us/v3/__https://agu.confex.com/agu/agu24/prelim.cgi/Sessi... Please consider submitting an abstract by the July 31st deadline. Session Description: Volatile elements (C, H, N, S, and noble gases) are crucial for planetary habitability, shaping long-term chemical and dynamic evolution. Despite significant strides in understanding volatile budgets and effects on rheological and thermodynamic properties of mantle materials, uncertainties persist regarding their origin, distribution, and transport in Earth and other terrestrial planets. This session invites contributions to deepen insights into volatile compositions, exchange fluxes between surface and interior reservoirs through geologic time, and their influence on mantle dynamics and surface processes. Welcoming diverse perspectives from geochemistry, cosmochemistry, geophysics, planetary science, experimental petrology, and theoretical modeling, this session fosters inclusivity and invites submissions from early-career scientists and underrepresented communities. Through the exploration of these fundamental questions, our objective is to expand our comprehension of volatile dynamics within Earth and planetary interiors, thus enhancing our understanding of planetary evolution and habitability. Best regards, Conveners: Lucia Bellino (University of Texas at Austin), Ananya Mallik (University of Arizona), Ekanshu Mallick (Tulane University of Louisiana), Anna M. Rebaza (University of Arizona)
