[iris-bulk] EGU General Assembly session

[IRIS]

Dear colleague,

We would like to remind you of the following session at the
European Geosciences Union (EGU) General Assembly, to be held in
Vienna, Austria from April 13-18, 2008:  "Realistic modelling and
inversion of high-frequency seismic and electromagnetic wave phenomena
in the shallow subsurface".  A description of the session is included
below.  The deadline for abstract submissions is January 14, 2008, and
the conference website can be found at:
http://meetings.copernicus.org/egu2008/

We hope to see you in Vienna.

High-resolution seismic and georadar methods have great potential for
resolving the highly complex structure of the shallow subsurface.
Moreover, these methods are critically sensitive to some of the most
interesting and pertinent petrophysical parameters for environmental
and engineering applications.  Whereas the velocities of seismic and
georadar waves are sensitive to porosity and water content, the
attenuation of seismic waves may be indicative of changes in
permeability or rock quality and the attenuation of georadar waves is
often linked to clay content.  During the last two decades,
acquisition technologies as well as modelling and inversion algorithms
for high-resolution seismic and georadar data have seen immense
progress.  Although the innovations in data acquisition have been
readily embraced by the community, the adoption of corresponding
innovations in modelling and inversion methods has moved more slowly.
Clearly, this is problematic as it means that the immense improvements
in the potential resolution of seismic and georadar data are not yet
fully realized.  Indeed, it can be argued that the use of modern
modelling and inversion technologies holds the promise of improving
the resolution of seismic and georadar data by roughly one
order-of-magnitude, thus pushing it into a realm that is directly
compatible with borehole logging data.  Moreover, modern inexpensive
computing platforms make massive modelling and inversion feasible to a
broad community.  The purpose of this session is to explore the
possibilities and limitations of modern modelling and inversion
algorithms for high-resolution seismic and georadar data under
real-world conditions, and to promote their use by the broader
community of practitioners in these domains.
