Magnetic Resonance Sounding for groundwater

Posted by on Thursday, 24 December, 2009

Anatoly Legchenko (LTHE, IRD, France) and Ugur Yaramanci (LIAG, Germany) report on the 4th International Workshop on the magnetic resonance sounding (MRS) method applied to non-invasive groundwater investigations, held in October at the University Joseph Fourier, Grenoble, France.

Magnetic resonance sounding (MRS) is a recently developed method for hydrogeophysical exploration. The very first soundings were carried out between 1979 and 1981. Since 1996, when a new generation of MRS equipment became commercially available, the number of MRS users has been increasing. Arrival of this geophysical method initiated intensive scientific discussions and exchange of experience. Apart from traditional geophysical meetings, these exchanges were channelled through specialized workshops: Berlin, 1999; Orléans, 2003; and Madrid, 2006.

While the efficiency of the MRS applied to groundwater-related studies is already proven, many technical details are still under development. A new generation of hardware and continuing progress with software are expected to improve accuracy and robustness of the technique. Thus, MRS workshops continue contributing to development of the method and establishing new scientific collaborations.

The 4th International Workshop was organized by the Laboratoire d’étude des Transferts en Hydrologie et Environnement (LTHE), Grenoble, France in co-operation with the Leibniz Institute for Applied Geophysics (LIAG), Hannover, Germany. The organizer got scientific support from different research organizations and national geological surveys; Near Surface Geoscience Division (NSGD) of European Association of Geoscientists & Engineers (EAGE); Institut de Recherche pour le Développement (IRD), France; Berlin University of Technology (TUB), Germany; Université Joseph Fourier (UJF), France; Federal Institute for Geosciences and Natural Resources (BGR), Germany; Bureau de Recherches Géologiques et Minières (BRGM), France; and Instituto Geologico y Minero de España (IGME), Spain.

Organization of this event was made possible thanks to financial support of BRGM, IRIS-Instruments, and LTHE, and the administraton of Grenoble city. The MRS2009 workshop was attended by 81 participants from 19 countries. In total, there were 46 contributions to the workshop given by scientists from different countries.

Communications and discussions during MRS2009 Workshop took place in a friendly and constructive atmosphere and covered a large spectrum of subjects related to instrumentation, data processing, modelling, inversion, and field results. The technical programme consisted of different topics addressing all aspects of MRS.

It has already become a tradition to publish the most significant contributions on MRS in special issues of European geophysical journals. For MRS2009 it was decided that a special issue of Near Surface Geophysics will be prepared. This will also be open to authors who did not attend the workshop but want to submit original article related to MRS method. The deadline for submission is set to 31 December, 2009.

Looking ahead, the 5th International Workshop on MRS will be organized in Hannover in fall 2012.
