Geophysical Survey in Fermanagh

DIAS is currently carrying out an academic research program that aims at an evaluation of geophysical imaging methods, which are needed for a better understanding the subsurface. The identification of subsurface structure and properties is important for many potential uses, such as CO2 long term storage or geothermal energy, with a strong commitment to environmental safety.

This research aims at reducing Ireland's CO2 footprint, either by reducing its emissions by reducing hydrocarbon usage, or by inhibiting greenhouse gas emissions from existing producers (e.g. power stations) entering the atmosphere, where it would aggravate human-made climate change. Both, long-term underground carbon storage and the use of geothermal energy, are seen worldwide as technologies which contribute to the smooth movement from the extensive use of fossil fuels to the use of renewable energy sources. While there are no plans for carbon storage in Ireland, geothermal energy may play a limited role in this process. However, a better knowledge of the subsurface, and the development of techniques to reliably image it are essential in the wider framework of European and worldwide research and technology development.

About Us

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".
