IAVCEI 2013 session 3-1 on ocean island volcanism
From: "Poland, Michael" <mpoland@xxxxxxxx>
****************************************************************************************
Dear Colleagues,
We encourage you to
submit an abstract to session 3-1, “Origin, evolution and eruption of
ocean island volcanoes” at the 2013 IAVCEI General Assembly, to be held
in Kagoshima, Japan, July 20-24.
The goal of the session is to highlight fundamental
questions regarding ocean island volcanism and new research that
addresses such problems by bring together a diverse group of researchers
(geophysicists, geologists, and geochemists) that study a range of
environments (from the mantle to the atmosphere). It is hoped that the
session will advance the case for a research initiative focused on ocean
islands.
Abstracts are due January 31, and can be submitted via http://www.iavcei2013.com/abstract_submission/abstract_submission.html
Best wishes for a Happy New Year!

Session description:
Ocean
island volcanoes are the largest on the planet, amongst both the most
frequently erupting and best monitored in the world. Moreover, many
ocean islands are inhabited and understanding their formation and
evolution has a direct impact on society. While mantle plumes are widely
believed to be involved in the genesis of ocean island basalts, the
thermal and/or chemical roles of large low-shear-velocity provinces in
the lower mantle are more contentious. Subaerial and submarine studies
have identified the importance of flank instability in the evolution of
oceanic volcanoes, but the uncertain source of such instability hampers
efforts to monitor unstable volcanic flanks for signs of large
earthquakes or collapse, and the distribution of such features is poorly
known except for a few archipelagos. The diversity of settings in which
ocean island volcanoes are found facilitates exploration of the
relation between environmental and surface characteristics. Frequent
eruptive and intrusive activity (including the recent recognition of
abundant explosive eruptions, particularly due to hydrovolcanism)
provides an opportunity to study the manifestations of volcanism on the
solid Earth, hydrologic systems, biota and atmosphere. A better
understanding of ocean island systems will aid in efforts to forecast
not only volcanic eruptions but also changes in island evolution and
climate that are of obvious importance to society.
This session will focus on new frontiers of research
at ocean island volcanoes from the deep mantle through to surface
eruption. The recent surge in interest in ocean islands as
multidisciplinary laboratories will ensure that the session is of broad
interest to deep Earth geochemists/geophysicists/geodynamicists,
volcanologists, geomorphologists, atmospheric scientists and climate
change experts. The session will identify the most critical problems
needing future work on ocean islands and advance efforts to form a
coalition of researchers that will focus on forecasting changes in the
activity and development of ocean island volcanoes.
