Working Group I.2 of IAGA - Electromagnetic Induction in the Earth ================================================================== Electronic Newsletter #4: October 1993 -------------------------------------- This is the fourth electronic newsletter for our group. A newsletter will be sent around when there is enough material, or a special event about to come up, to warrant distribution. Not all of us in the working group have access to email address; if you are aware of colleagues who are not likely to receive this newsletter, please give them a paper copy (but chastise them for using trees instead of electrons). Also, please forward this to colleagues who may not yet be on my email list and ask them to forward their address to me. ***IMPORTANT*** PLEASE READ THE NEWS ITEM ABOUT "TUTORIALS" FOR THE BREST WORKSHOP AND GET SUGGESTIONS TO PASCAL TARITS (tarits@univ-brest.fr) BY OCTOBER 31ST 1993.

Argentina 1993 Working Group Meeting ========================================== General: -------- Although the initial session on the first day (1.3: Large-Scale Magnetic & Electromagnetic Anomalies in the Continental Lower Crust) was poorly attended, particularly by the speakers (only two papers given), the remaining sessions were reasonably well-attended. There were 505 registrants for the meeting, and for session 1.8 (Interpretation of conductivity models of the continental lower crust: Fluids or carbon - can we tell the difference?) there were over 55 in the audience. Minutes: -------- The Working Group meeting was held on 13 August 1993, and began at 17:00. There were thirty (30) scientists in attendance (list available from A.G. Jones on request). The items discussed were: 1. Brest: Pascal Tarits gave details of the 1994 Brest EM induction meeting (see 3 below), complete with slides of the town. 2. Cambridge: Alan Jones gave details of the 1994 Cambridge MT-DIW2 meeting (see 4 below). ***NOTE THAT these two meetings are being held at two locations for logistical considerations, and that the wish of the committee is for attendees of the MT-DIW2 also to go to the EM induction meeting. There is a "stick-and-carrot" approach being used: the stick is that you cannot register for the MT-DIW2 alone, you must register for both. The carrot is that we have arranged the two meetings back-to-back, with a coach going from Cambridge to Brest through scrumpy (very strong cider!) country (but keep in mind that you have a channel crossing to follow!). 3. Workshop topics: Al Duba gave an update of the topics for the Brest meeting. Reviewers were suggested for some sessions, and they are being approached. 4. Committee membership: Four members retired/resigned from the committee. In their place, four new members were elected from a nomination slate. 5. email: Al Duba discussed the impact of email on the group. Some sentiment existed for ensuring that those who do not have access to email receive the electronic newsletters. Wally Campbell offered to post the newsletter out. 6. Topics for Boulder: It is necessary to give Inter-Association and Association session topics to the IUGG for consideration for the 1995 IUGG meeting to be held in Boulder. A long discussion occurred concerning the clashes at Buenos Aires between the sessions for WG I.2 (EM Induction in the Earth) and WG V.5 (External/Internal Relations). To try to ensure that that does not happen again, it was decided that all sessions should become joint sessions. The following were discussed. Those that were accepted were allocated possible session chairpersons and lengths. UNION: ----- These topics were suggested at the Wellington meeting. IUGG have yet to decide which, if any, to accept. Those that are not accepted will be offered as possible Inter-Association ones. Geophysical Signatures of Mantle Dynamics Weak Zones in the Lithosphere Fluids in the Continental Crust ---also a possible session on the re-use of telephone cables. See item 5. Inter-Association: ------------------ IAGA/IASPEI Long-wavelength Geophysical Anomalies in the Continental Lithosphere -discussed in detail. M. Mareschal commented that her 1992 magnetics/electro- magnetics AGU session and the similar session at Argentina (1.3) had failed to be inter-disciplinary. Not accepted when voted on. IAGA/IASPEI Tectono-magnetic studies -discussed in detail. Decided to let IASPEI be the lead if they are interested. Hjelt to contact IASPEI.

Brest 1994 EM Induction Workshop ====================================== The First Circular has been sent out. You should all have received a copy by now. If you haven't received one by the end of the month, please contact the workshop organizing committee on the email address listed below. As a reminder: Dates: 8th - 14th August 1994 Location: Brest, France Registration Fee: 700 FFR Local Organizing Committee: Tarits, Menvielle, Schultz, ... Program Committee: Duba, Jones, Tarits, ... Workshop email: EMW@univ-brest.fr Reviews: -------- ***REVIEWS MUST BE IN TO PASCAL TARITS BY 1ST JUNE 1994. This is a requirement, and by accepting to undertake a review, you agree to provide a draft version for distribution at the meeting. Tutorials: ---------- There has been the suggestion that we have a couple of tutorials at this workshop. These tutorials would try to bring us all to state-of-the-art in certain aspects, rather than our present state-of-the-practise. You are asked three specific questions: 1. What topic do you want a tutorial on? 2. Who do you want to give it? 3. Would you be prepared to give a tutorial, and on what topic? Please reply to Pascal Tarits AS SOON AS POSSIBLE. Certainly prior to the end of October. -------------------------------------------------------------------------------- >>>4. MT-DIW2 ============= Magnetotelluric Data Interpretation Workshop 2 (MTDIW2) Venue- University of Cambridge, Institute of Theoretical Geophysics, Department of Earth Sciences Registration- Those participants in the 13th Workshop on Electromagnetic Induction in the Earth who wish to participate in the 2nd Workshop on MT Data Interpretation in Cambridge immediately prior to the main workshop, will be able to do so when they register for the main workshop. Pre-registration is essential as space is limited for the MTDIW2. It is the intention of the organizers of the MT Data Interpretation Workshop and the Induction Workshop that the participants in the former also attend the latter. If there are exceptional circumstances preventing you from attending the Induction Workshop, and you want to participate in the MT Data Interpretation Workshop, please contact A. Schultz at adam@esc.cam.ac.uk to discuss your particular situation and separate registration. Participation in the MTDIW2 involves agreeing to analyze at least ONE, and (you are encouraged to do this) possibly more, of the MTDIW2 datasets that will be made available to participants. Attendees will be expected to come to the MTDIW2 ready to discuss their analysis and interpretation. Computing facilities (workstations, Geotools, etc.) will be available during the proceedings to test ideas that arise during discussions. Itinerary- 4 August 1993. Arrive evening; participants make their own arrangements for evening meal. Accommodation in St. John's College Cambridge, bed & breakfast. 5 August 1993.

Re-use of submarine cables ================================= IAGA, IASPEI, and IAPSO have appointed a Joint Committee on the Scientific Reuse of Submarine Cables to coordinate and facilitate applications of submarine telephone cables to scientific applications. Alan Chave has been asked to chair the group, and the individual representatives are Lou Lanzerotti of Bell Laboratories (IAGA), Junzo Kasahara of the Earthquake Research Institute, Tokyo (IASPEI), and Jim Larsen of NOAA in Seattle (IAPSO). In addition, Leo Vanyan and Adam Schultz have been invited to join this group. A Union session on scientific applications of submarine cables has been proposed for the IUGG meeting in Boulder. Further details will be announced when this is approved. For more information, please contact Alan Chave (alan@faraday.whoi.edu). -------------------------------------------------------------------------------- >>>6.

AGU GP Email network =========================== Suzanne Beske-Diehl, Secretary of the Geomagnetism and Paleomagnetism Section of AGU, has set up an email network. Below are her instructions. [Note: the comments about EM people may have been sparked by my remark (and obviously others) to her that I did not want to become inundated with paleopole positions.] Instructions for the GP E-mail Network (9/93) Please have a copy of these instructions handy for future reference. The long awaited Geomagnetism and Paleomagnetism Network is now up and running on Michigan Technological University's computer system. 1) You are welcome to submit timely announcements, news items, and scientific problems or questions to the network. 2) If you respond to an item carried over the network, send the response to the PERSON WHO SUBMITTED THE ITEM. 3) The person who originally submitted the topic is responsible for writing a summary of the responses and sending the summary to the network. 4) Upon recommendation from experienced network users, I will be monitoring all items before they are sent out on the network. Only under extreme circumstances of poor taste or frivolous content will I edit any material. Having never done this before, I'm not quite certain what to expect. Many of the electromagnetists have expressed an interest in receiving information only about electromagnetism and related items, whereas the rest of the GP e-mail members are interested in numerous topics in Geomagnetism and Paleomagnetism. Because of these requests, I have established two different networks, one for general geomagnetism and paleomagnetism and one for electromagnetism. A person can be on both lists. To send mail through the network: For GP network simply address mail to: gpmag@mtu.edu For Electromagnetics network address mail to:elmag@mtu.edu To subscribe to a network: For GP network address request to:gpmag-request@mtu.edu At Subject: field type "subscribe" Example - Subject:subscribe Text does not matter. For Electromag network address request to:elmag-request@mtu.edu At Subject: field type "subscribe" Example - Subject:subscribe Text does not matter. To unsubscribe to a network: For GP network address request to:gpmag-request@mtu.edu At Subject: field type "unsubscribe" Example - Subject:unsubscribe For Electromag network address request to:elmag-request@mtu.edu At subject: field type "unsubscribe" Example - Subject:unsubscribe To change your e-mail address: Unsubscribe first (this can be done from the new address) and then subscribe using you new e-mail address. note: Always send subscribe and unsubscribe requests to the -request address of a mailing list. The Executive Committee of the GP Section of AGU hopes that these e-mail networks will increase communication between GP members. Please feel free to use the network. Address any problems, suggestions, complaints or comments to sbeske-d@mtu.edu..

Classified Ads ===================== Leasing of GSC's LIMS equipment ------------------------------- The GSC now has a compliment of sixteen (16) long period magnetotelluric systems we call LIMS. Each system measures five components, and is programmable to record data windows in up to three frequency bands. The 5 Mb RAM memory means that with 5 s digitizing interval, you can record for up to 28 days unattended. A car battery will power a system for just over 7 days. These LIMS are available for leasing when they are not being used on GSC surveys. The rates per instrument per month for an academic institution are (in Canadian dollars): GSC survey in Canada : no charge Non-GSC survey in Canada : $ 250 Joint GSC/Other survey outside Canada: $ 500 Non-GSC survey outside Canada : $1000 PLUS a one-time charge of $250 per instrument for pre- and post-survey calibration, packing, etc. In addition, you will be required to pay all transportation costs, and to show that you have taken out insurance to cover the full replacement costs of the instruments. Electrodes telluric wire, and batteries are not supplied. Also, a high speed link card and a PC computer are required (avaliable on request: rate to be determined). As these instruments cost us approximately $22,500 each to build, the above rates are a bargain. The commercial rate is $2500 per instrument per month. As well as the LIMS systems, you will be provided with codes and C-shell scripts for splicing, time series analysis, decomposition analysis, and various plot displays (if you have a UNIRAS license). For more information, please contact Alan Jones, Dave Boerner or Ron Kurtz (jones@cg.emr.ca, boerner@cg.emr.ca, kurtz@cg.emr.ca). Research Associate position --------------------------- We hope have a position for a Research Associate within the Ottawa EM group beginning after October 1st 1994 for a period of two (2) years. The programme is run for us by NSERC, and applications MUST be in to them by November 15th 1993 to start in the period April 1st 1994 - January 31st 1995. The group's interests are wide-ranging, from regional studies using mostly MT to high- resolution controlled-source studies in mining camps. The current renumeration is of the order of C$37,000 per annum. For more information, please contact Alan Jones, Dave Boerner or Ron Kurtz (jones@cg.emr.ca, boerner@cg.emr.ca, kurtz@cg.emr.ca). -------------------------------------------------------------------------------- Alan G Jones Ottawa, October, 1993 -------------------------------------------------------------------------------- IAGA Working Group I.2 Internet email list: 12 September 1993 ------------------------------------------------------------- Additions/corrections/deletions to: jones@cg.emr.ca Temporary addresses identified by termination date A bracketed (R) after the address indicates that mail was returned from that address when last sent.
