Convener’s report
about the session Electromagnetic images of the Earth
(session no. MPRG11) at the EGU General Assembly, Vienna, 27 April 2005
by L. Szarka and F. Kolbeck
In the MPRG 11 session („Electromagnetic images of the Earth”) all the six oral presentations, and 10 of the 13 scheduled poster presentations were correctly held. Only Pérez-Flores M.A (from Mexico, with two posters), and Gürer A. (from Turkey with one poster) were not able to come.
About 20-25 people attended the oral session (held between 8:30-10:00). It was chaired by the convener and the co-convener. The oral session dealt with magnetotelluric case histories from various regions as Iberia (paper 001 by Pous et al.), Carpathians (paper 003 by Stefaniuk et al., paper 004 by Kovacikova et al.), Trans European Suture Zone (STZ, paper 005 by Brasse et al.). One of the two theoretical papers presented a new concept for the cancellation of man-made electromagnetic noise (paper 002 by Moorkamp et al.), another paper discussed a system of rotational invariants of the MT tensor that preserves its all information content (paper 06 by Szarka).
During the poster session the conveners asked short oral presentation from authors of each poster. The estimated total attendance of the poster session was about 50. At the poster presentation besides several further MT case studies (STZ by Smirnov and Pedersen, paper Z302; Ireland by Rao et al., paper Z303), an active electromagnetic survey of hydrothermal venting area at the mid-atlantic ridge (Sinha et al., Z301), a geomagnetic induction study using a novel technique (Lemperger et al. Z305), a reconstruction study of the MT tensor from its invariants (Novák, paper Z304), MT response distortion during a solar eclipse (Ádám et al., Z306), and a novel DC technique (Z304, Szalai et al.) were presented. Three posters were definitely enviromental problem-oriented: Ranieri et al. (Z307) applied DC and EM geopysics to study eutrophic phenomena, Turai and Dobróka (Z311) presented a waste-site characterisation using IP data, Baracza et al. (Z312) showed joint geoelectric and seismic results about waste sites.
A quite a large number of geoelectric-electromagnetic (especially) MT results were presented at various other sessions. Electromagnetic parameters (especially the electrical conductivity) are more and more used in subsurface geological characterisation from a few decimeters scale to mante depths.
In 2006 the next EGU will take place again in Vienna. In spite of numerous meetings (EM induction workshops, IAGA, UGGI, EAGE, EEGS, etc.), we think, it is important for EM geophysicists, especially for magnetotelluricians, to have their own session also at EGU assemblies. In 2006 we are proposing a rather theoretical (methodological) session, under the title e.g. „Magnetotellurics and other EM geophysics”, or simply „EM geophysics”, where would be worth inviting one or two solicited papers, in order to increase the attractivity of the session. At the same time, it would be useful to see as many EM case history papers at other sessions, as possible. Furthernmore, we are proposing to have more co-conveners (perhaps from those EM geophysicists who attended the EGU meeting this year).
