3-3-3-3-3-3-3-3-3-3-3-3-3 From: Adam Martin <a.martin@xxxxxxxxxx> Time is fast approaching for The IAVCEI Scientific Assembly 2023 in Rotorua, New Zealand, from 31 January to 3 February 2023. We want to draw your attention to the session and encourage you to submit an abstract to the following session: Symposia:* Magmatism and tectonism* Session:* Volcanism in Antarctica and the Southern Oceans* Description: Cenozoic volcanism in Antarctica and the Southern Ocean is an important part of the geological and palaeoenvironmental record. At least six active volcanoes and dozens of major volcanic centers are exposed in Antarctica and surrounding oceans. The hazard of effusive and explosive volcanism to life and logistics in Antarctica, from both active and dormant volcanic centres, is still poorly understood. Further, remote sensing has identified over 80 subglacial volcanic vents in West Antarctica. Igneous petrology aids in understanding the driving mechanisms of Antarcticaâ??s tectonic development, and fundamental knowledge of mantle properties beneath the Antarctic Plate are revealed through the integration of geochemical and geophysical data sets. Important aspects of past ice sheet conditions, such as ice thickness and thermal regime (ice sheet stability), are best answered by looking at lavaâ??ice interactions in a field of study known as glaciovolcanology. Ice cores provide valuable climate records extending back for 800 ka; they have an extensive tephra and aerosol record. This multidisciplinary session will be open to presentations on all aspects of Antarctic and Southern Ocean volcanism and will include, but not be limited to, the following topics: Tephra records; Relationship of volcanism to tectonic history; Nature and petrology of volcanic rocks; Mantle dynamics and sources of volcanism; Activity associated with Erebus volcano lava lake; Remote and geophysical studies of volcanoes; Glaciovolcanology; Volcanic hazards and monitoring. The deadline for abstract submission is 2 September 2022. Your conveners, Adam P. Martin (lead), Nels Iverson, Philip Kyle, Kurt Panter 3-3-3-3-3-3-3-3-3-3-3-3-3 ------------------------------
