TWO NEW PhD OPPORTUNITIES IN SEISMIC and RHEOLOGICAL MODELLING
Two PhD studentships are available in the Geophysics Section of the
Dublin Institute for Advanced Studies to work in the areas of (1) seismic
wave propagation, and (2) rheological and thermal modelling of Earth
structures.
1. Seismic Wave Propagation
In this project finite difference code will be developed and implemented
on the DIAS parallel computer cluster to solve the whole visco-elastic
wave equation for complex geological structures. The project will involve
developing numerical techniques to extract all of the information present
in real high frequency seismic coda. One anticipated avenue of research
is the use of generic algorithms in searching for realistic model
solutions to the observed seismic wavefield. The geophysical focus will
be on the complex basin-fill structure within the Rockall Trough where,
recently, very detailed seismic data has been collected. The student will
work with researchers working on seismic data from the region using
traditional ray-racing and tomographic techniques. The project will
require a mathematics, physics or earth sciences degree with a keen
interest in computing and programming.
2. Rheological/Thermal Modelling
The rheological modeling will initially be built upon largely conceptual
kinematic models for sedimentary basin formation in the North Atlantic
region. These have been developed using the results from our
wide-angle-seismic studies in the area. The approach taken will involve
solving the appropriately modified Navier Stokes equations, which are
realistically coupled to lithospheric rheological properties and thermal
structure to understand the fundamental processes that lead to the
formation of structures from orogenic belts to sedimentary basins. New
techniques towards tackling these problems will be developed. The student
will work with an experienced Senior Research Fellow who has expertise in
this field along with the existing staff in the School of Cosmic Physics
and will be part of a large group of researchers working on related
problems. This project forms a part of the DIAS-led Cosmogrid project
(http://www.cosmogrid.ie/) involving a wide range of Grid-enabled
computional physics of natural phenomena. When complete the grid will
comprise three linked 200-300 node Beowolf clusters. The candidate should
have, or be about to obtain a BSc or MSc or equivalent in
theoretical/computational physics with an interest in geophysical studies.
The stipend attached to the studentships is 13,000 Euro per annum plus
university fees. Interested candidates should contact either Dr Peter
Readman ([log in to unmask]) or Dr Brian O'Reilly ([log in to unmask]) for further
details.
