If you wish to discuss any items, please contact either your committee representative, or our Chairman, Al Duba. Minutes of IAGA WG 1.1 Committee meetings: Brest, August 1994 ------------------------------------------------------------- -------------------------------------------------------------------------------- 9 August: Committee Meeting I -------------------------------------------------------------------------------- Meeting commenced at 12:45 In attendance (anti-clockwise from the Chair): Duba Jiracek Ingham Osella Jones Pedersen Tarits Honkura Szarka Junge >1. Discussion of agenda for Brest WG business meeting; agenda items 1A. Workshop venue for 1996 - two formal offers - Indian & Japan - presentations to be made during business meeting - no offer from China - tentative offer from MIT (Mackie) in honour of Ted Madden - offer from McElhinney for workshop joint with Western Pacific AGU to be held in Brisbane 13 - 17 July, 1996. After discussion, it was resolved that:- THE COMMITTEE THANK McELHINNEY FOR THE OFFER, BUT WISH TO PROCEED WITH AN INDEPENDENT ELECTROMAGNETIC MEETING 1B. Workshop format - discussion ensued about possible formats for the next workshop. Should there be greater effort at having tutorials? No decision made, except that it was re-emphasised that the format is at the discretion of the host local organising committee. 1C. Topics for next Workshop - topics for the next workshop must be decided upon at Boulder. All members will be encouraged to think about this and send suggestions to one of the committee members. 1D. Boulder - WG business meeting during Boulder will be held on Friday 7th July - Hjelt to present the 7 WG sessions 1E. Charley Swift - discussion about how to send Charley Swift our best regards. Decided to purchase a book and have everybody sign it. 1F. Books - Duba to inform the group of the two new EM books (Weaver, and Zhdanov) 1G. Hohmann Meeting - There will be a meeting in honour of Jerry Hohmann at Schlumberger-Doll research labs in 1995. 1H. MT-DIW's - Jones to give brief presentation on status of MT-DIW's. Discussion ensued about this workshop: - number of *new* people increased. Good sign. Bodes well for the future of our field - funding for young scientists and some senior scientists explained by Duba, Jiracek, Tarits and Jones. - Jiracek considers that the industry support base could be expanded. - Duba expressed regret that there are so few Africans at this workshop. He was pleased to see such a large South American representation. - Would there be travel support for Boulder? AGU? U.S. State Dept.? JIRACEK to check.--------------------------------------------ACTION ITEM >2. Committee Membership Replacements - There will need to be replacements for Duba, Fainberg, and Singh at the Boulder IUGG meeting. - Duba explained the process. - The committee makes a recommended list and presents it to the members. - Members may add any name they desire. - If there is more than one name from any particular country, then a vote ensues - with the affected members absent - to pick one candidate. - If there are more candidates than positions, a vote ensues, usually by written ballot, to select the replacements. - The committee consider that both the U.S. and the F.S.U. should have representation on the committee. - Some discussion ensued about possible candidates. >3. Holding every third workshop in various locations - It had been suggested to Duba that every third workshop be held in many locations, much like the regional AGUs. This would enable those who are unable to attend the main workshop to attend their regional one. - Jones stated his objection, with the view that there was already regional geophysical meetings that EM people could congregate at. - Ingham also voiced his strong opposition. - The consensus of the committee is that this is not a good idea, and is likely to fractionate the community. >4. Support Form - There is a need to obtain certain specific baseline data in order to make an assessment for financial support. JIRACEK, JONES and TARITS to provide form in time for Boulder IUGG.--------------------------------------------------------ACTION ITEM Meeting adjourned at 14:10 -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- 9 August: Business Meeting -------------------------------------------------------------------------------- Meeting called to order at 19:45 Discussion items: A: Venue of 1996 workshop B: Format C: Topics D: MT-DIW E: IUGG Boulder 1995 F: Charley Swift G: Books H: Hohmann I: Financial support J: EGS meeting, Hamburg 1995 B: Format --------- Duba said that our workshops are tending to become like an AGU with formal presentations. We are losing the "workshop" spirit. What should we do to get this back? Should there be for example a "Best Student Paper Award"? Raiche opposed this, with the concern that the content suffers. The talks should be about ideas, even off-the-wall ideas, rather than finished pieces of work. Nobes agreed. Constable made a plea for far more discussion of oral presentations. Jones thought that there should be fewer oral presentations, but that each one should be allocated more time. Chouteau wanted presentations to focus on themes. Constable supported the idea of having the posters up for the whole duration of the workshop, rather than just for the specific session. He suggested that all papers be posters, and that the program committee pick out what's currently "hot". Schmucker wondered if we should break into workshop clusters. Hobbs disagreed vehemently. Single session for our workshop is very important. He also agreed with Constable that there should be some focusing of themes at our workshops. Chave opined that the format of a particular workshop must be left in the hands of the program committee to decide. Raiche agreed with Chave. Jiracek made a plea to have oral presentations give a simple message. Smith wanted more time to view the posters. Schultz wondered whether there should be more specialist sub-workshops, along the lines of the MT-DIWs. Or perhaps we should have parallel sessions. Duba felt strongly that there should be only one session. Consensus views were:- - posters should be up the whole time - single session only - program committee to decide format based on number of abstracts etc. C: Topics --------- All informed that they should let members of the WG Committee know possible topics for the 1996 workshop. G: Books -------- All informed about the two books recently published. I: Financial Support -------------------- Thanks were expressed to those who worked hard to obtain financial support for travel funds. Jiracek, Tarits, Spies and Strack. H: Hohmann meeting ------------------ All informed about Schlumberger-Doll EM meeting to be held in honour of Jerry Hohmann. E: IUGG Boulder 1995 -------------------- Hjelt gave the outline of the EM sessions at Boulder. Seven scientific sessions, with a WG Business Mtng on 7 July, and a IAGA Div I Business Mtng on 8 July. Abstract deadline is February 1st, by mail or email. Extra copy of abstract to go to principal convener of session. J: EGS meeting, Hamburg 1995 ---------------------------- Brown described the special session that he is convening at the Hamburg EGS on April 4-7 on "EM studies of the lithosphere". The conveners are Brown, Tezkan and Pec. F: Charley Swift ---------------- Jiracek described Swift's condition, and that a book was available for those to sign who wanted to send their best wishes. D: MT-DIW --------- Jones reported on the MT-DIWs: MT-DIW1: JGG special issue out. Editors of JGG very happy with the result. MT-DIW2: Cambridge. 37 participants. 27 presentations. 4 datasets. Brief results of modelling exercise conducted at Cambridge shown. MT-DIW3: Will take place. Location unknown at present. Dependent on location of 1996 EM workshop. Will take two new datasets. A 3D Japanese dataset, plus another one. A: Venue of 1996 workshop ------------------------- RP Singh made a presentation for his proposal to hold the 1996 workshop in Kanpur. time: some week in August or first week of September. But best time for dates is over Indian winter Oct - Feb. How fixed is workshop to August? Wednesday -> Thursday suggested. venue: IIT, Kanpur Kanpur is a city of 2.5 million, 300 sq km.

Division I Chairman Duba reported that IAGA Division I will need a new Chairman at the Boulder meeting. Jones wondered whether there was an informal understanding in Div I that the chair be rotated between EM and paleomag interests? If so, then must be time for paleomag candidate. >2. ILONEM ILONEM is still in place, but has no "person" and no funds for inviting people. Jones thought that the need for a centralised facility was less now than previously given the advent of Internet and the electronic access to computers and modelling codes. Pedersen expressed his agreement with this. Duba to relay consensus of committee to Hjelt. >3. South American project Duba had received a letter from Borzotta (Mendoza) asking the WG to support a proposed project with Rokityansky to take place in South America. After discussion, it was agreed that JONES, PEDERSEN and OSELLA would provide a written review of the scientific aspects of the proposal. ---------------------------------------------------------------------ACTION ITEM >4. Reminder about topics for next workshop >5. Membership. Reminder to think about members for 1995 meeting. >6. Support form to be ready for Boulder. >7. Fainberg stated that at recent Russian EM meeting; the consensus was that Svetov replace Fainberg on the committee. Duba explained the procedure; that the replacement is by democratic vote of ALL the members present at the business meeting, not just of a geographical group. >8. Location of next workshop After lengthy discussion, it was unanimously agreed to accept Japan's offer to host the 1996 workshop.
