V24A:
Glacial Cycles and Volcanism on Land and Undersea I


Session ID#: 9126

Session Description:
Glacial cycles transfer large masses between continents and oceans.
Since melt generation and volcanism are influenced by pressure,
glacial cycles have the potential to influence volcanism on
glacial/interglacial time scales. As the ultimate source of volatiles
to surface systems, volcanic cycles can then influence the climate
system. Recent work provides evidence for glacial cycles influencing
subaerial volcanism as well as submarine volcanism and hydrothermal
activity at ridges. Further linkages exist that may have implications
for glaciation and the biosphere, including between volcanism and CO2
emissions and amongst hydrothermal activity, seawater chemistry, and
sediment compositions. Exploration of these linkages is just
beginning, and existing evidence and models have elicited controversy.
This session provides a forum for recent evidence and counter-evidence
in the form of models and observations pertaining to the linkages
between climate and the solid Earth on glacial/interglacial time
scales.
