Introduction

Research into the structure and dynamics of the Earth uses a range of physical and mathematical techniques and is grouped into the three main themes of Seismology and Mathematical Geophysics, Geophysical Fluid Dynamics, and Geodynamics and Geodesy. The work spans observational, theoretical, laboratory, computational and data oriented studies, all directed towards understanding the structure and physical processes in the earth's interior, the crust or the earth's fluid envelope. New staff commencing during 2007 include two new continuing faculty members: Dr H. Tkalcic in observational seismology and Dr A. McC. Hogg in ocean modelling. Postdoctoral staff members P. Arroucau and M. Salmon joined the seismology group. PhD students A. Abdulah, J. Hauser and E. Saygin graduated. Read More...
