The IAG Newsletter is under the editorial responsibility of the IAG Central Bureau chaired by the IAG General Secretary. In each issue of Journal of Geodesy the newsletter includes the following topics: Informations. Reports of IAG symposia. Reports by National Correspondents. Reports from IAG Special Study Groups. Symposia announcements. Book reviews. Fast bibliography. It is the intent of the IAG to extend the services provided by its Central Bureau. An up-to-date information medium is one of the key elements. The IAG Newsletter, included as appendix of the Journal of Geodesy, should play this role, and therefore be considered as an open forum. Contributors are welcomed to send any information or document (preferably in electronic form) which may b e of interest for this purpose. This should complement the informations already send by the IAG officials or the IAG symposia organizers (reports and announcements). Books to be reviewed are under the responsability of : Dr. Herman van Gysen Department of Surveying and Mapping University of Natal King George V Avenue Durban 4001, South Africa, E-mail: gysen @superbowl.und.ac.za and Prof. Martin Vermeer, Finnish Geodetic Institute, Geodeetinrinne 2, (PL 15), SF-02431 Masala, Finland, E-mail: Martin.Vermeer @fgi.fi

1. Adoption of Agenda The agenda was adopted as tabled. 2. Priorities for the next four years K-P. Schwarz opened the discussion on priorities and asked the EC to evaluate how successful IAG has been in the following fields: 1) Coordinating international projects, 2) International services, 3) International schools, 4) Scientific meetings, 5) Special Study Groups (SSG) and Commissions, 6) Publications, 7) Highlighting IAG research, 8) Developing countries, 9) The general profile of IAG, 10) Interactions with other organisations.

375 The general conclusions were that lAG has been successful in fields 2 and 4, and has, in general, done well in 5 and 6: Improvements are, however, needed in the fields 7, 8, 9, 10. It was discussed how lAG, as a non-commercial organization without research funds, can have an impact on scientific decisions of international importance. It was agreed, that IAG should strengthen activities in fields 1,3, and 7-10 and come up with a list of priorities for the period 1995-1999. The EC agreed, that K-P. Schwarz will draft a list of lAG priorities for further discussion. Among the themes discussed were: IAG funds are tight and lAG basically needs more money to become more efficient (e.g. to initiate more schools). IAG should strengthen the interaction with SSGs and highlight outstanding SSG results in the Journal of Geodesy. SSGs should be more involved in international schools and meetings, both in the preparation of these events and in organizing sessions. It was noted that the SSG's are vital and important for the future of the lAG organisation. There is uneven global distribution of lAG activities, and an effort should be made to improve IAG's global presence. IAG is for instance much stronger in Europe than in North America. Its presence in developing countries depends largely on individuals active in these countries. lAG should strengthen the coorporation with other organizations. C.C. Tscherning agreed to improve contact to groups like the European Geophysical Society (EGS), the American Geophysical Union (AGU) as well at other international geodetic societies. 3. Minutes of Boulder meeting A draft version of the Minutes of the Boulder meeting was distributed by P. Willis, and the former EC was asked to make corrections to the draft version before final distribution. 4. Rapport on 'Travaux' The Travaux for the period 1991-1995 was distributed by P. Willis. It was suggested that IAG should explore the possibility of electronically distributing the Travaux, and only send out a few printed copies. 5. Follow up on Boulder resolutions The IUGG and lAG resolutions wili be published with the Handbook. English and French versions are already available from the IAG home page. The IAG home page is accessible through the Internet on World Wide Web at URL: http://www.gfy.ku.dk/-IAG/. Only the IUGG resolution #2 has so far been followe d up. The Central Bureau will write to sponsors and ask them to report on the follow-up. 6. Proposal for new IAG fellows The IAG general officers for the period 1991-1994 became fellows at the IAG meeting in Boulder. In Boulder the five chairmen of the subcommissions of the Special Commision SC1 were proposed as fellows by the SC president E. Grafarend. The EC accepted this proposal and elected: B. Schaffrin(USA), R. Klees (Germany), F. Sacerdote (Italy), J. Zund (USA) and A. Drozyner (Poland) as new IAG fellows. It was noted, that presidents of subcommissions do not automatically become IAG fellows. In the future, the EC will discuss the election of those subcommission presidents who have been proposed by their commission presidents.

7. Committee on developing countries (CDC) After getting written input from former members of the CDC, the EC decided on a new structure for this committee. It will consist of a global coordinator and three regional coordinators, one each for Africa, SE Asia and S. America. The EC elected F. Sanso as global coordinator and M. Chodota as the regional coordinator for Africa. The other two regional coordinators will be appointed after consultation with active IAG affiliates in these regions. Each regional coordinator will be asked to invite four other members from the region to the committee, considering a distribution that reflects a good balance in terms of geography and geodetic activity. The committee may want to consider a new name, replacing 'developing' by a more appropriate term. For the time being, the term 'developing' will be used in the UN definition of the word. 8. Report on status of Journal of Geodesy (JG) C. C. Tscherning gave a report on JG. Prior to the meeting a status report on JG based on a report distributed by the new editor in chief, P. Teunissen by e-mail prior to the meeting. Status is, P. Teunissen has taken over from P. Vanicek and C. C. Tscheming. The backlog of accepted manuscripts (about 300 pages) has been dealt with by expanding the last issues of Bulletin Geodesique(BG)and Manuscripta Geodetica (rag) by a total of 160 pages, and by making the first JG issue a double issue. Ole Andersen has taken over the preparation of the IAG Newsletter, which will be distributed as an appendix to the JG, with C. C. Tscherning as responsible. The cost of subscription (per page) will be the same for the JG as for the combined subscription to the mg and BG. The total subscription will be higher because the JG has two more issues per year. The price for IAG affiliates will also be the same as before. Twenty copies will be available for free distribution to institutions (libraries) in developing countries. The selection of these institutions will be made by the Central Bureau. 9. Report on Finances and IAG Fund The lAG council has approved the following budget (all values in US Dollars): Income 1.995-1999 IUGG 1000005 Publications 10005 Springer Verlag 40005 AGU (Boulder) 100005 Total 1150005 Expenditures for 1995-1999 Administration Publications (Travaux) Symposia Grants Bomford price Total Surplus

530005 260005 80005 40005 10005 1010005 140005

The Central Bureau would like to review the expenditures with a view to re-allocating funds from administration to the support of meetings and new IAG initiatives. The review will take into account the new financial arrangements for the bureau at the University of Copenhagen and the actual expenditures for the period 1991-1995. However, P. Willis

376 informed that during the past four years administrative costs had already been re-allocated into support for participation in the EC meetings. It was suggested that the costs of publishing and distributing the 'Travaux' could be considerably reduced if electronic media (floppy Disks, CD-rom, only few printed copies) are used. This would require, that as much material as possible is received in electronic form by the Central Bureau in the future. P. Willis pointed out that the current cash situation is very good. The IAG fund which is administered independently has a healthy balance and will be increasingly used to supply travel grants to young scientists from developing countries and to support IAG workshops in these countries. The Central Bureau will also propose a budget for the IAG fund. 10. Report on Handbook P. Willis reported on the status of the Handbook, which will be published before summer 1996. IAG should have received the list of national delegate, but information on national representatives from a number of important member countries is still missing. The IAG homepage contains all important documents to be published in the handbook. It is regularly updated and should always be consulted for the most current information. Changes in addresses should be immediately reported to the Central Bureau in order to keep the IAG records and the information on the IAG homepage up-to-date 11. Charge-back policy The revised of the policy on IAG products was distributed by K-P. Schwarz. The revised policy was accepted with minor corrections and will be published in the Handbook and in the IAG Newsletter. It should serve as a general guideline for all IAG bodies. 12. Review of new structure. Terms of reference for most SSGs and special commissions are available and preliminary membership lists have been received. The information currently on the homepage will be updated accordingly. The individual sections were presented by the section presidents, who reviewed the status of their sections and agreed to pass on the following suggestions: Section I. Two SSG on subjects related to GPS did not have US representatives. The SSG presidents should consider this. Section II. It was accepted by the EC, that A. Marshall (NASA/GSFC) becomes chairman of SSG 2.162 for which C.K. Shum had originally been proposed. Section III. No response from the chairman of SSG 3.166 has been received. If no written proposal is obtained by mid December, the steering committee has EC approval to close down the SSG. Section IV. The EC proposed to create a new special study group no. 4.176 "Temporal variations of the gravity field" and simultaneously to remove the subcommission 6 from SC1. Section V. The SSG 5.173 should have the word "seafloor" removed from its name. Hence SSG 5.173 will become "Interaction of the Atmosphere and Oceans with the Earth's rotation dynamics". SSG 5.173 president (C. Wilson) should be notified about this. EC asked for a narrower target for SSG 5.172, and recommended, that members from countries endangered by earthquakes (e.g. around the Mediterranean) should be invited to join the SSG.

Finally the commissions were presented by the commission presidents. The president of section 5 (M. Feissel) suggested, that PSMSL is being affiliated with SC8. Hence PSMSL would report to the president of SC8. This was approved by the EC. 13. Decision on scientific program for Rio de Janeiro and Melbourne Melbourne (Joint symposia with IAPSO and IAMAS, 1997) K-P. Schwarz had asked for suggestions prior to the EC meeting. There was general agreement that in view of the IAG scientific assembly at Rio, no separate IAG symposia should be held at Melbourne. The following joint symposia were proposed for Melbourne: 1) Satellite oceanography and altimetry. (IAG/IAPSO, IAG leadership proposed) IAG convenor: R.S. Nerem Session topics (furiher topics to be added by IAPSO) a) Geoid and ocean circulation. b) Global sea surface topography and tile geoid. c) Altimetry and height datum. 2) Atmospheric research using space geodetic methods. (IAG/IAMAS, leadership to be decided) lAG convenor: W.G. Melbourne. 3) The interdisciplinary impact of earth rotation studies. (IAG/IAMAS/IAPSO; IAG contributing) IAG convenor: C.R. Wilson The title for symposia three proposed by IAPSO was: Ocean atmosphere angular momentum budget and earth rotation. Rio de Janeiro (IAG scientific assembly 1997) W. Torge presented the state of preparations for the 1997 lAG meeting in Brazil. A Local Organizing Committee (LOC) has been set up in Rio with Denizar Blitzkow as lAG representative. The first circular has been distributed and contact has been made with UNESCO). The Brazilian LOC plans to charge between 1805 and 2305 for registration (depending on time of registration). The LOC will make available at least 10 rooms to scientists from developing countries. If topics fall into areas of UNESCO priority, W. Torge, in cooperation with the LOC, will further explore this possibility. The EC created a committee consisting of W. Torge and the section presidents to propose session topics in the three major areas: Positioning and reference frames Gravity and geoid Geodynamics. The list of topics will be distributed by e-mail to all EC members and the Brazilian LOC. The scientific program should be finalized and published early in 1996. 14. IAG coordinators for Rio de Janeiro and Melbourne (responsible for liaison with LOC) W. Torge was elected as IAG coordinator for the IAG meeting in Rio de Janeiro (IAG scientific assembly, September 3-9, 1997). J. Dickey was elected as coordinator for the IAG contribution to the Melbourne meeting (Australia, July 1-9, 1997).

377 15. Proposal for a fundamental geodynamic reference network I.I. Mueller introduced the proposal which had been distributed prior to the meeting. He stressed the importance of involving other associations of the IUGG and of actively promoting this effort internationally. The EC asked I.I. Mueller, G. Beutler and K-P. Schwarz, to establish a working group with representatives of all key organizations and IUGG associations and to define its terms of reference. The working group should focus on the following: The distribution and location of stations, the scientific justification of the project, and the need for seismic and magnetic data. The working group should come with recommendations before the Rio meeting.

22. Preparation of future EC meetings In order to make future EC meetings more efficient K-P. Schwarz asked the EC to adopt the following guidelines: 1) Only items for which the presence of EC members is required and which cannot be clarified by e-mail will be discussed at future EC meetings. 2) Background information on decision-items should be sent out by e-mail two weeks ahead of the EC meeting. 3) The action required should be clearly stated in the background documents. At the meeting only a brief summary of the essential points will be expected. 4) Responsibility for the action required should be explicitly stated after the decision has been made. The guidelines were adopted.

16. Applications for sponsorship of meetings, schools etc. No applications have been received by the Central Bureau after the Boulder meeting.

23. Other Business R. Forsberg was appointed as coordinator of fundraising for the IAG fund. He will be in charge of writing letters to raise funds at regular intervals in coorporation with the Central Bureau.

17. Establishment of a permanent IAG research archive in Paris. A proposal to set up an IAG research archive within the IGN structure had been distributed prior to the meeting. The EC agreed to the proposal and asked a small committee consisting of C. Boucher, P. Willis and C. C. Tscherning to find a name for the archive and report back to the EC. The tentative was agreed by the EC. 18. Creation of an IAG software service F. Sanso presented the proposal which has been distributed by e-mail prior to the EC meeting. A committee consisting of H. Sunkel, H-G Wenzel, P. Knudsen (Denmark), C. C. Tscherning and Y. Bock will determine the scope of such a service within IAG and make a proposal to be elected at the Rio meeting. 19. Establishment of a committee to coordinate initiatives for IAG schools F. Sanso and C. C. Tscherning submitted a proposal to extend and diversify the program currently offered by the scientific and technical lAG schools. Besides covering a wider range of topics, the possibility of linking this program with EU initiatives in this area was discussed. It was felt that this proposal needed further discussion and a committee consisting of G. Beutler, F. Sanso, I. Mueller, R. Rummel, B. Heck, P. Holota, and R. B. Langley was established to present options for lAG initiatives at the next EC meeting. F. Sanso was asked to start the discussion in this group via e-mail. 20. Bibliographic services C.C. Tscheming reported on his discussions with representatives of the IFAG bibliographic service and the possibility of using the IFAG as bibliographic service. The Fast bibliography in the IAG Newsletter could in future be based on a subtile of the IFAG bibliography. A mandate was given to organise the coorporation with the IFAG services. However, it is important that C. C. Tscherning stresses the importance of using English as language for the IAG subtile. 21. Procedure for selecting best paper award The guidelines for selecting the lAG best paper award was distributed at the meeting. The guidelines were adopted as proposed and will apply to papers published in the new Journal of Geodesy.

The next meeting of the IAG EC will take place in early 1997 at a location to be determined.

Symposia Announcement International Symposium on Gravity, Geoid, and Marine Geodesy 1996 (GraGeoMar 96) IUGG,IAG,MTS 30 September - 5 October 1996 Tokyo, Japan Ist Circular Letter (Revised 09 Feb. 1996) The National Committee for Geodesy, Science Council of Japan, Geodetic Society of Japan, Japan Society for Marine Surveys and Technology, in collaboration with and under the auspices of the International Association of Geodesy and its Commissions III (Gravity) and XII (Geoid), together with the Marine Geodesy Committee of Marine Technology Society, have the honor of inviting you to participate in the International Symposium on Gravity, Geoid, and Marine Geodesy t996 (GraGeoMar 96) in Tokyo, Japan, 30 September to 5 October 1996. This symposium is co-sponsored by the Earthquake Research Institute and the OceanResearch Institute of the University of Tokyo, the Seismological Society of Japan, and the Oceanographic Society of Japan. Study of gravity and geoid of the Earth is making progress rapidly with the aid of advanced observation techniques. Precise 'Positioning', 'Absolute and Relative Gravimetry', 'Determination of Sea Surface Topography', 'Modelling of the Geopotential' and so forth are innovating not only the field of geodesy but also global geosciences in general. These studies have become crucial in order to understand global geodynamics, earthquake prediction, ocean dynamics and the Earth's environmental changes. Although it is only two years since the successful IGC andlCG Symposium in Graz and the INSMAP94 in Hannover in 1994,the exceedingly rapid progress in the field makes it advantageous to provide a forum for demonstrating current results of studies on gravity, geoid, and marine geodesy and

378 for exchanging information among the researchers of the world. Participation of researchers from countries in the Pacific area is particularly encouraged. Date: 30 September(Mort) - 5 October(Sat), 1996 Gravity and Geoid: 30 September - 4 October Marine Geodesy: 1 October - 5 October Location: Sanjo Kaikan Conl'erence Hall, University of Tokyo 7-3-1, Hongo, Bunkyo-ku, Tokyo 113, Japan Scientific Sessions: Various topics of gravity, geoid and marine geodesy will be considered by the Local Organizing Committee. Although thetitles of the sessions will be announced in the Second Circular,the following sessions are now proposed. Tentative Session Plan (1) Progress in absolute gravimetry (2) Progress in relative gravimetry (3) Space and Airborne gravity and gradiometry (4) Altimetric gravity and Geoid (5) Best-fit processings for local geoid: Pacific zones and Europe (6) Geophysical inversions of gravity, geoid and displacement (7) Standards, networks, data bases and software (8) Modelling of terrestrial gravity potential (9) Earth tide observation and evaluation (10) Global gravity geodynamics (11) International project and advanced technique (I 2) Tectonogravimetry (13) Sea floor geodesy (14) Sea level changes (15) Sea surface positioning (16) Electronic charting and unification of datums (17) Ocean floor mapping Registration and Fees: All the participants will be required to register and pay either of the following fees.

XVIII Brazilian congress of Cartography Scientific Assembly of the International Association of Geodesy September 3 - 9, 1997 Rio Centro Rio de Janeiro - RJ, Brazil. First Circular Letter

XVIII Brazilian congress of Cartography, Scientific Assembly of the International Association of Geodesy. Since 1987, during the XIX IUGG General Assembly, the International Association of Geodesy (IAG) was looking for an invitation from any country in South America to hold the Scientific Assembly. Efforts have been done in Brazil in the last few years in order to arrange favourable conditions to address an invitation to IAG, Finally in the beginning of 1995 a meeting has been organized by the Brazilian Society of Cartography, Photogrammetry, Geodesy and Remote Sensing (SEC) with representatives from the main institutions involved with geodesy in Brazil. A special committee has been

379 established and an important decision taken to address an invitation to IAG to hold the scientific meeting in 1997. At the Boulder meeting the executive committee of IAG accepted the invitation of Brazil. It will be a joint meeting of the XVIII Brazilian congress of Cartography and the 1997 Scientific Assembly of lAG. The meeting will be held in the city of Rio de Janeiro, in the RIOCENTRO Congress Center. There will also be an exhibition XVI EXPOSICARTA, with most modern equipments of geodesy, photogrammetry, cartography and softwares.
