Geophysics - About Us

The Geophysics Section studies the tectonic and dynamic structure of the Earth using methods of physics combined with the other geosciences - geology, geochemistry, petrology, geochronology etc. The main areas of research are electromagnetism, seismology, geodynamics and potential fields (gravity and magnetism).

In all sub-disciplines of geophysics, the Section has theoretical, numerical and observational activities.

The ElectroMagnetism and Inversion group undertakes studies of the Earth from the shallow subsurface (100 m) to deep in the mantle (1000 km) using both active and passive EM methods. Forward and inverse methods for 3-D modelling of EM data are being advanced, as are joint inversion approaches for rigorously combining EM data with seismic and other data.

The Global Geophysical Modelling group undertakes numerical modelling studies of Earth behaviour, from ice dynamics and post-glacial rebound to deep Earth mantle electromagnetism.

The Seismology and Geodynamics group undertakes observational and numerical studies at the regional to global scale.

The Marine Seismology group studies primarily Ireland's offshore region using both active and passive sources.

In addition to geophysical research, the Geophysics Section maintains the Irish National Seismic Network (INSN), which presently comprise five broadband seismic stations. One of these, DSB in the Dublin Mountains, is part of the Geofon global network run by the GeoForschungsZentrum Potsdam, and another, VAL in Valentia, is operated in conjunction with Met Eireann.

Also, the Section is the National Data Centre (NDC) for Ireland's contribution to the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization. Tom Blake is the Principal Point of Contact (PPOC) at the NDC for the CTBTO Preparatory Commission. View footage of the DIAS participation in the CTBTO Field Inspector Training Excercies.

The Mallet Professorship of Seismology in the Geophysics Section is named after a famous Irish scientist, Robert Mallet 1810-1881, also known as the "father of controlled source seismology".
