The Workshop will be held at the Conference Hall, Le Quartz, situated in the centre of Brest. Brest is an important commercial and naval port bordering the Rade de Brest, a road-stead at the western edge of Brittany. HOST The Universite de Bretagne Occidentale has been chosen to organize the 12th international Workshop on Electromagnetic Induction in the Earth. With an annual enrollment of 20,000 students, it is the second largest university in Brittany. CLIMATE Day-time temperatures during July and August vary between 18 and 25 C with night-time temperatures rarely falling below 12 C. The weather is changeable and rain may occur at any time. We therefore suggest that you bring adequate clothing and a raincoat or umbrella in addition to your summer clothes - just in case! LETTER OF INVITATION Upon request, the Secretariat will send a personal invitation to participate in the Workshop. It should be understood that such an invitation does not represent a commitment on the part of the organizers to provide any financial support. INSURANCE The Workshop organizers cannot accept liability for personal accidents or loss of, or damage to, private property of delegates and accompanying persons, either during or indirectly arising from the 12th Workshop on Electromagnetic Induction in the Earth.

From Brest to Brigognan , the "Lighthouse Road" offer an unique journey along the Aber coasts and the coasts of Legends. Imagine the scenic view from the top of the lighthouse of l'Ile de la Vierge, the highest lighthouse in Europe. For sure, you will forget you have ascended 392 steps! Thursday 11th: Mystic Brittany >From 13:00 to 18:00, cost: 150 FFR A trip through the religion and the origin of Brittany, from the old Celtic times to the 16th and 17th century religious period. The delicately carved granite sculptures, Breton churches, calvaries and "chapelles" bear witness to the mysticism which has always pervaded this Celtic country. Friday 12th: Visit to Quimper >From 9:30 to 16:00, lunch open, cost: 200 FFR This is the main administrative town of Finist re, situated in a pretty valley at the junction of the Steir and Odet Rivers.

MT-DIW2 ============= This is the text of the letter being sent out by Adam Schultz to those who have expressed an interest in attending the MT-DIW2. If you have any comments, please contact either Adam Schultz or myself on: adam@itg.esc.cam.ac.uk and jones@cg.emr.ca (Note: due to problems of a bewildering nature, Adam's email is occasionally "down". Do not dishearten! Cambridge gnomes eventually defeat the email gremlins.) Second International Workshop on Magnetotelluric Data Interpretation MT-DIW2 Cambridge, England 4-7 August 1994 26 January 1994 Dear MT-DIW2 Respondent, You have expressed interest in attending MT-DIW2. This conference, to be held in Cambridge immediately prior to the Induction Workshop in Brest, and linked to that workshop, has generated considerable interest, and the response to the first circular has been very strong indeed (136 as of today). We now find it necessary to ask potential participants to pre-register formally for the MT-DIW2. We have reserved 50 rooms (bed & breakfast) at St. John's College, Cambridge, and are now financially liable for the cost of these rooms. It is therefore necessary to ask for partial payment of these expenses in order to reserve you a place at the MT-DIW2. Rooms will be allocated in the order that pre-registration payment is received. Any pre-registrations arriving after the 50 rooms have been allocated will be accepted with the understanding that those additional participants will have to make alternative (more expensive) hotel arrangements. MT-DIW2 Overview The purpose of the MT-DIW2 is to bring together active researchers in magnetotellurics and electromagnetic induction, and given the task of interpreting one or more common datasets, to exchange information about the current state-of-the-art in interpretation. It is therefore necessary for all participants in the MT-DIW2 to be active participants, prepared to give a short presentation (either oral or poster) on their analyses of one or more of the datasets provided them by the organisers of the MT-DIW2. MT-DIW2 is not meant as a forum for more general discussions, nor is it intended as a place to give a talk about interpretation of any datasets other than ones provided by MT-DIW2. The main Induction Workshop in Brest is the most suitable location for such talks. There are three conditions with which all participants in MT-DIW2 must agree: Participation is limited to those prepared to discuss their analysis of one of the MT-DIW2 datasets; participants should be prepared to send a short (2 page) summary of their work to the organisers one week prior to the workshop (for distribution to participants upon registration); and attendance is linked to registration for the Brest Induction Workshop. Failure to register for the Brest Workshop will invalidate any registration for MT-DIW2. One way coach and ferry transportation between Cambridge and Brest will be provided as part of MT-DIW2. MT-DIW2 Datasets: Three MT-DIW2 datasets are available. The first dataset has been provided by Chevron (Australia), and is comprised of ten sites of MT data acquired using a Phoenix MT-16 system from a more extensive survey of Papua New Guinea. These and all data available for MT-DIW2 (as well as COPROD2) span frequencies of 384 Hz-1820 s. (These data will probably be available by mid-February) The second dataset has been made available by Exxon (USA), and is from an EMAP survey from Oklahoma (USA), comprising 93 dipoles, with E-field measurements all in-line (no cross-line measurements), supplemented with 4 perpendicular strike MT sites. The data available are the Zxx and Zxy responses. (Available now) The third dataset is BC87, first distributed to participants of the MT-DIW1 in Wellington. This comprises MT and GDS responses from 27 sites over a 150 km traverse with 40 responses in the above frequency band. The profile is from the Valhalla Gneiss Complex to the Rocky Mountain Trench in SE British Columbia, Canada. (Available now) All three datasets are available in SEG/EDI format, J-format and Geotools+ db archive format. Although the COPROD2 dataset will not be a theme of this MT-DIW, poster space will be available if anyone wishes to show further analyses of these data. Accessing MT-DIW2 Datasets: The preferred method of obtaining these data is via electronic access using `ftp' over the Internet. For those not connected to Internet, please contact Alan Jones at the Geological Survey of Canada, or Adam Schultz at the University of Cambridge, to obtain the datasets on disk or tape. Internet access: First, connect to MTNET using `anonymous ftp'. For users in Europe, Africa and the Near East, we recommend you connect to the European node of MTNET. For users in the Americas, East Asia and Australasia, we recommend you connect to the North American node of MTNET. mtnet-europe.esc.cam.ac.uk (131.111.44.20) mtnet-northamerica.cg.emr.ca (132.156.40.93) example: ftp mtnet-europe.esc.cam.ac.uk Name: anonymous Password: Your Name@ Your machine address cd pub/mtnet/mt-diw2/okemap get README ...read the README and decide which files you want bin get emap.edi.Z get mt.edi.Z ... quit Preregistration: The total estimated expense in pounds sterling for attending the MT-DIW2 is as follows: 1. St. John's College, bed & breakfast, 3 nights * 30.00 per night 90.00 2. Lunch in Department, coffee, tea during conference * 2 days 14.00 3. Conference Dinner, St. John's College, semi-formal, 1 night 17.00 4. Registration fee (for cost of mailing, materials, etc.) 20.00 5. Coach (bus) from Cambridge-to-Plymouth, then Roscoff-to-Brest 30.00 6. Breakfast on coach 5.00 7. Brittany Ferries, crossing from Plymouth England to Roscoff France 34.00 ----------------------------------------------------------------------------- TOTAL GBP210.00 Other anticipated expenses include cost of disks or tapes for those unable to access MT-DIW2 datasets over the Internet; dinner(s), for pre-conference night of 4 August, and also free night (possible pub crawl) on 6 August; cost of pub lunch en route to Plymouth, Devon from Cambridge via coach, and of course, any expenses associated with atten- dance at the Induction Workshop in Brest, and any onward travel from there. Those staying at hotels rather than the student-style accommodation of St. John's College will need to make their own booking arrangements. We therefore require a (non-refundable) deposit of GBP67.00 (1 night Bed & Breakfast at St. John's College, conference dinner, and registration fee), postmarked by 4 March, in order to secure pre-registration. Those requiring MT-DIW2 data on disk or tape, rather than over the Internet, will need to include an additional GBP10.00 to cover costs of media and postage. The balance of GBP143.00 is required by 2 June. At the time of writing, GBP1.00 = USD$1.49. Payment must be in UK funds and can be accepted in the form of Eurocheques, Bank Drafts, Postal Orders, or personal cheques payable on a UK bank. Please return the enclosed form with your pre-registration.

Boulder, 1995 =================== This is the list of the Division I sessions for the IUGG 1955 Boulder from Sven Hjelt. There will be some minor changes to symposia 1.3, 1.5+5.13, and 1.9. I do not have a list of the Union or Inter-Divisional symposia. 1.1.+2.8.+3.16.+4.5.+5.5. Solar wind structures, energetic solar particles, geomagnetic activity and associated phenomena. John T. Gosling, MS D466, Los Alamos National Laboratory, Los Alamos, NM 87 545 USA (fax: + 1 - 505 - 665 7395; e-mail: jgosling@sstcxl.lanl.gov) D. H. Tarling (UK), J. Lastovicka (CZECH REP) and A. Berthelier (FRANCE) The aims of this symposium are to explore the physical linkages between structures and events in the solar atmosphere with those in the solar wind near 1 AU and to examine how the resulting interplanetary structures, disturbances, and energetic particle events perturb the magnetosphere, the ionosphere and the atmosphere. Emphasis in the symposium will be on interdisciplinary studies that cross the boundaries between solar, interplanetary, magnetospheric, ionospheric, and atmospheric research. 1.2. Relating geophysical measurements to lithospheric processes through continental drilling. Prof. Volker Haak, GeoForschungsZentrum Potsdam, Telegrafenberg, D-14407 Potsdam, GERMANY (fax: + 49 - 331 - 288 - 1235; e-mail: vhaak@gfz-potsdam.de) J. Erzinger (GERMANY), J. Mutter (USA) and D.R. Schmitt (CANADA) Continental deep drilling will become a major tool in obtaining a better understanding of continental crustal structures and processes. Geophysical remote sensing methods have revealed numerous anomalies of uncertain origin. Observations from wellbores penetrating the source of the anomalies can be used to study the state of the stress, the proximity of the rock to ductile transition, the existence of open fracture porosity, the geochemistry of sampled fluids producing a geophysical signature and the causes of electrical conductivity of structures. Multidisciplinary experiments in the vicinity and within deep boreholes, and on fresh core samples in the laboratory could provide insights of local problems useful to a more general understanding of the formation of the continental crust. The session welcomes papers on all these aspects. 1.3. The "D" layer and interactions between the core and deep mantle. Professor Kathy Whaler, Department of Earth Sciences, University of Leeds, Leeds LS2 9JT, UK (e-mail: whalerK@earth.leeds.ac.uk) The nature, thickness and composition of the D" layer, and the topography of the core-mantle boundary (CMB), although not fully understood, may play an important role in the dynamics of the core. There is a variety of geomagnetic evidence for interactions between the core and deep mantle, including stationarity of features of the geomagnetic field at the CMB and the angular momentum budget on the decade timescale. Seismological, experimental high pressure-temperature and geomagnetic studies give complimentary information providing together new insight into the nature of the D" layer. This interdisciplinary session welcomes contributions discussing any aspects of the D" layer and core-mantle interactions. 1.4. Core dynamics and the dynamo. Professor C. A. Jones, Mathematics Department, University of Exeter, Exeter EX4 4QE, UK (fax: + 44 - 392 - 263 997; e-mail: C.A.Jones@maths.exeter.ac.uk) G. Glatzmaier (USA) The session will cover following topics: numerical and theoretical models of the geodynamo: reversal mechanisms; convective processes relevant to the inner core;role of magnetic instabilities in core dynamics; electromagnetic and topographic core-mantle coupling; effects of lateral inhomogeneities; effects of mantle precession on core dynamics. Contributions on non-magnetic aspects of core dynamics will also be welcome. 1.5. + 5.13. Geomagnetic secular variation and core flow near the core-mantle boundary. Dr. Gauthier Hulot, IPGP, Laboratoire de Geomagnetisme et Paleomagnetisme, CNRS UA729, 4 Place Jussieu, B89, Tour 24, 75252 PARIS Cedex 05, France (fax:+ 33 - 1 - 44 - 27 33 73; e-mail: ghulot@ipgp.jussieu.fr) Dr. R.A. Langel (USA) This session will be devoted to studies that characterize and interprete the time variations of the main magnetic field on all time scales from very short (such as those involved in magnetic "jerks") to secular ("secular variation"). Authors are encouraged to present interpretations in terms of consequencies for the flow near the core-mantle boundary. Global studies that simultaneously investigate all time scales or those that make use of independent non-magnetic data (such as astronomical or seismological data) are especially welcome. 1.6. Reversals: observations and theory. Professor D. Gubbins, Department of Earth Sciences, University of Leeds, Leeds LS2 9JT, U.K. (e-mail: gubbinsd@earth.leeds.ac.uk) B. M. Clement (USA) The session will encompass any palaeomagnetic or geomagnetic data and analyses that advance our understanding of reversals. Especially papers on following topics are welcome: analysis of observatory annual means, geomagnetic impulses and jerks, and global secular variation modelling; fluid flow near the core-mantle boundary, flux diffusion, and magnetic diffusion in the mantle; the origin of secular variation and implication of secular variation studies for physical processes in the Earth's deep interior; the recent exciting suggestion that the transitional VGP's from different reversals exhibit a preference for certain paths 1.7. Lithospheric anisotropy: observations and interpretation. Marianne Mareschal, Genie mineral, CP 6079, succ. Centre Ville, Montreal, CANADA, H3C 3A7 (fax: + 1 - 514 - 340 4191; e-mail: marianne@geo.polymt1.ca) Michael Bostock (CANADA) The focus of this session will be on upper mantle anisotropy either electrical or seismic. However, papers dealing with crustal anisotropy will also be accepted. Special attention should be given to the interpretation of data and possible constraints on the source(s) of anisotropy. 1.8. Geophysical signatures of modern and ancient continental margins. John R. Booker, Geophysics AK50, Univ. of Washington, Seattle WA 98195, USA (fax: + 1 - 206 - 543 - 0489; e-mail: booker@geophys.washington.edu) M. Christina Pomposiello (ARGENTINA) There are a variety of large interdisciplinary projects being undertaken worldwide to focus on modern and ancient continental margins with a spectrum of techniques (seismology, electromagnetic induction, palaeomagnetism, geodesy, geochemistry, geology etc.). The purpose of this session is to provide a forum for reports from these groups with particular emphasis on the synergistic value of multiple approaches to a problem. 1.9. Patterns in the Earth's structure and dynamics: observations, Earth models, and laboratory measurements. Steven Constable, Scripps Institute of Oceanography, La Jolla, CA 92093-0225, USA (e-mail: Steve_Constable@igppqm.uscd.edu) A. G. Duba (USA), J.P. Poirier (France) and I. Jackson (Australia) 1.10 Multidimensional mathematical advances in EM induction: decomposition, modelling and inversion. E. Gomez-Trevino, CICESE, Geofisica, POB 434 843, San Diego CA 92143-4843, USA (fax: 1 - 706 - 674 4502; e-mail: egomez@cicese.mx) T. Smith (UK) Recent development in electromagnetic induction is focussing on robust data processing techniques such as decomposition, and increasing the dimensions of models used to assist in the inversion of measured data. Although promising three-dimensional techniques have been presented, much development is still needed to improve the realistic modelling of geoelogical structures. The session is open for papers on all aspects of theoretical and practical development in electromagnetic modelling and inversion. Papers discussing the application of new methods to real data sets are warmly recommended. 1.11.+2.16.+5.8. Multidimensional currents over multidimensional Earth structures: theory and observations. Alan G. Jones, Geological Survey of Canada, 1 Observatory Crescent, Ottawa, Ontario, CANADA K1A 0Y3 (fax: + 1 - 613 - 992 8836; e-mail: jones@cg.emr.ca) A. D. Richmond (USA) and E. W. Mbipom (NIGERIA) The characteristics of geomagnetic variations at diurnal periods and less are influenced by spatial structure in the external currents and in the electrical conductivity of the Earth. Although considerable work has been done in the past either to model the source currents as fully three-dimensional, but the Earth's conductivity structure as one-dimensional, or else to consider a uniform source field over a multidimensional Earth, the need to treat both the external currents and the Earth conductivity as spatially structured is increasingly becoming evident. In this session we seek papers that address the actual situation of multidimensional, time-varying, current sources over multidimensional Earth structures. Both theoretical and observational studies are welcome. 1.12. Electromagnetic studies of the solid Earth. Steven Constable, Scripps Institute of Oceanography, La Jolla, CA 92093-0225, USA (e-mail: Steve_Constable@igppqm.uscd.edu) S.I. Fontes (BRAZIL) and X. R. Kong (CHINA) This session is designed for papers dealing with electromagnetic studies but which do not fit descriptions given for other sessions. Field, laboratory and theoretical studies of EM induction and electrical conductivity in Earth and earth materials are welcome. 1.13. Magnetic signature of environmental change. Subir Banerjee, Institute for Rock Magnetism, School of Earth Sciences, University of Minnesota, 310 Pillsbury Drive, S.E., Minneapolis MN 554455-0219, USA (fax: + 1-612-624 3819; e-mail: geologi@umnacvx) Jan Bloemendal (UK) For a truly quantitative interpretation of magnetic signatures of environmental change, it is necessary to acquire new mineral magnetic data for the relevant magnetic oxides, hydroxides and sulfides. This session will deal with both basic and applied rock magnetic studies that can quantify the infuences of temperature, humidity, mineralogy, microstructure amd chemistry on the magnetic proxy records of environmental change, past and recent, as well as direct studies of those records themselves. 1.14. Archaeo- and paleo-secular variations. Charles E. Barton, Australian Geological Survey Organization, GPO Box 378, Canberra, A.C.T. 2601 AUSTRALIA (fax: + 61 - 6 - 249 9986; e-mail:cbarton@bmr.gov.au) Q.Y. Wei (CHINA) Compilations of archaeomagnetic data and time-series palaeomagnetic records provide information about geomagnetic secular variation beyond the last few hundred years. This session is devoted to results and analysis of archaeomagnetic data (including dating applications) and palaeomagnetic results from sequences of sediments, lava flows and cave deposits. Areas of particular interest include (i) high resolution extension of the observational record at the historical end of the timescale, (ii) development and validation of palaeointensity records from sediments, (iii) the statistical analysis and modelling of palaeosecular variation, and (iv) global approaches to the synthesis and analysis of long secular variation records. 1.15. Innovations in palaeointensity studies. Lisa Tauxe, Fort Hoofddijk, Budapestlaan 17, 3508 TA Utrecht, The Netherlands (fax: + 31 - 30- 53 5030; e-mail: ltauxe@magician.geof.ruu.nl) J.-P. Valet (FRANCE) Since the magnetic field is a vector, its intensity is an integral part of a complete description, yet, most palaeo-geomagnetic efforts have focussed on directional variability alone. The principle deterence from studying palaeointensity remains the difficulty of obtaining reliable palaeointensity data. This session will focus on new approaches to the problem of acquiring palaeointensity data from archeological and geological materials. We will also consider implications of data sets that have recently been obtained or analysed in a new way. 1.16. High-resolution magnetostratigraphy. C.G. Langereis, Paleomagnetic Laboratory, Utrecht University, Fort Hoofddijk, Budapestlaan 17, 3584 CD Utrecht, The NETHERLANDS (fax: + 31 - 30 - 53 5030; e-mail: langer@geof.ruu.nl ) John Shaw (UK) In recent years, new dating techniques - astronomical/climatic calibration and 40Ar/39Ar single crystal laser fusion techniques - have given a new impetus to high-resolution magnetostratigraphy, and the resulting polarity time scales differ significantly from those derived from sea-floor anomalies. In this session, we invite high resolution studies, in particular those that have an accurate time control. There will be an emphasis on the recognition and timing (age and duration) of short events and excursions to determine their global significance, to compare them with "cryptochrons" (or "tiny wiggles") derived from the ocean floor, and as an aid in resolving the time constants of the geodynamo. We also encourage studies that link (sedimentary) sequences to the GPTS, especially those studies that provide marine to continental correlations. 1.17. Nature of remagnetizations. R. Douglas Elmore, School of Geology and Geophysics, The University of Oklahoma, Norman, OK 73019-0628, USA (fax: + 1 - 405 - 325 3140; e-mail: delmore@geoadm.gcn.uoknor.edu) Trond H. Torsvik (NORWAY) The focus will be the characteristics (e.g., rock magnetic, geochemical) and identification of chemical, thermoviscous and strain-related secondary magnetizations. Other topics include the origin of Late Palaeozoic secondary magnetizations, palaeomagnetic dating of diagenetic events, and distinguishing secondary from primary magnetizations. Papers integrating geochemical, petrographic, and structural studies with palaeomagnetic investigations are particularly encouraged. 1.18. Palaeomagnetism and tectonics. Jean Besse, I.P.G.P., Lab. de Geomagnetisme et Paleomagnetisme, 4 Place Jussieu F-75252, Paris Cedex 5, FRANCE (fax: + 33 - 1 - 4427 3373; e-mail: besse@ipgp.jussieu.fr) Augusto Rapalini (ARGENTINA) and Jim Channel (USA) The last decade has seen a continual increase in the application of palaeomagnetism to studies of the evolution of the Tethys Ocean. This session will provide a forum to discuss the palaeogeographic and tectonic implications of the fast growing palaeomagnetic database of the Tethys area, and will concentrate on palaeomagnetic investigations of: (i) motion of main continents bordering the Tethys Ocean since the Palaeozoic times; (ii) dispersal and accretion of blocks in Caribbean and Tethyan area, and (iii) continental deformation of the Eurasian margin of Tethys. Contributions on palaeomagnetic studies of tectonic problems from other areas will also be welcome. 1.19. Applications of magnetic anisotropy. D. A. Clark, CSIRO, Division of Exploration and Mining, P.O. Box 136, North Ryde, NSW 2113, AUSTRALIA (fax: + 61 - 2 - 887 8874; e-mail: d.clark@dem.csiro.au) G. Borradaile (CANADA) and A. Kapicka (CZECH REP) Studies of anisotropy of magnetic susceptibility (AMS) and anisotropy of magnetic remanence (AMR) have numerous applications to geological problems, including determination of palaeocurrent directions of sediments, flow directions in igneous rocks, definition of tectonic fabrics, quantitative estimation of strain, and correction of palaeomagnetic directions for effects of anisotropy. Advantages of magnetic anisotropy measurements include high sensitivity, ease and rapidity of measurement, but interpretation of data is seldom straightforward. Papers are invited that discuss new experimental approaches, theoretical modelling of magnetic anisotropy in rocks, interpretation methodologies, or case histories of geological applications. 1.20. Properties of minor magnetic minerals. Mark J. Dekkers, Palaeomagnetic laboratory, Fort Hoofddijk, Budapestlaan 17, 3584 CD Utrecht, The NETHERLANDS (fax: + 31 - 30 - 53 5030; e-mail: dekkers@geof.ruu.nl) Buffy McClelland (UK) Our fundamental rock magnetic knowledge of magnetic minerals other than magnetite is underdeveloped. Contributions will be welcomed to this session dealing with fundamental rockmagnetic properties (hysteresis properties, thermal properties, magnetic transitions) as well as spectroscopic and other non-magnetic means of identifying minerals of palaeomagnetic interest (greigite, pyrrhotite, maghemite, (ilmeno-)hematite, goethite and other rarer natural magnetic minerals). 1.21. New approaches in rock magnetism. Convenors: Susan L. Halgedahl, Department of Geology and Geophysics, University of Utah, Salt Lake City, UT 84112-1183, USA (fax: + 1 - 801 - 581 7065; e-mail: sue@westlog.utah.edu) Franz Heider (GERMANY) Papers are invited on following topics: domain structures associated with different types of remanence; domain imaging techniques; observed versus theoretical domain structures; PSD versus MD behaviour - measurements versus theory; new techniques to characterize magnetic mineralogy; new techniques to characterize magnetic carriers and their domain state; new techniques to discriminate among different species of NRM; time/temperature stability of NRMs; and other topics suggested by contributing investigators. -------------------------------------------------------------------------------- >>>4.
