The SCAR Antarctic Volcanism (AntVolc) Expert Group aims to promote the study of Antarctic volcanism, facilitate regional correlations and work towards establishing Antarctica as a high profile site for studying volcanic processes, especially but not solely petrology and glaciovolcanism.
Volcanoes are widespread, at environmentally strategic locations across the entire continent; several are active
- Part of one of Earth’s largest crustal rift zones – the West Antarctic Rift System
- Outstanding probes of the Earth’s inaccessible lithospheric interior
- Erupted tephras ubiquitous in marine & ice cores; unrivalled tools for regional climate and time correlations
- Tephras are isochronous correlateable surfaces whose sources and ages can be determined
- Subglacial eruptions are unequalled sources of palaeo-ice sheet parameters (e.g. age, thickness, thermal regime)
- Volcanic heat during subglacial eruptions has the potential to modulate ice-sheet behaviour and stability, and influence global climate
So, volcanic studies are crucial for a holistic understanding of the palaeoenvironmental, palaeoclimatic & geological evolution (past and future) of the Antarctic Continent.
