Biographical Sketch: Colin Hogg graduated from UCD in 2004 after studying geophysics and continued in UCD until 2006 for post-graduate research in environmental physics. Following that he completed a Post-Graduate Diploma in Education (Maths, Science and Physics) at Maynooth University. During these years several internships brought him to Scripps Institution of Oceanography. In 2007, Colin joined the Geophysics Section of DIAS where he has been involved in research projects that have led him to work from Southern Africa to the Arctic and plenty of places in between.

Research Interests and Responsibilities

My general duties and responsibilities at DIAS comprise all aspects of magnetotelluric (MT) fieldwork, ranging from instrument preparation, logistics, survey design, data collection, analysis modelling and presentation of results. More recently I’ve been involved in seismic related fieldwork including data analysis from the Irish National Seismic Network  and I participate in field campaigns onshore and also the deployment of Ocean Bottom seismometers (OBS’s) in the North-West Atlantic as part of the Geophysics Section’s ongoing research.

I’m currently actively involved in two ongoing research projects.

(1) Geophysical imaging of the hydrothermal system beneath the Furnas caldera, Sao Miguel, Azores. This project, in collaboration with geophysicists at the Institute des Sciences de la Terre (ISterre) Grenoble, France and the University of Azores, aims to investigate the subsurface structure beneath the caldera at Furnas using audio-magnetotelluric (AMT) and electrical resistivity tomography (ERT) techniques.

(2) Space Weather research. I’m actively involved with the development of a space weather warning system with colleagues in the Physics Department of Trinity College Dublin. A network of magnetic and magnetotelluric observatories has been developed across Ireland in recent years, providing a near real-time indicator of the condition of our geomagnetic field. Solar storms can seriously disturb our geomagnetic field causing beautiful aurora but also increases the risk of damage to our electrical grids. See our recent data here.
