programme for Acapulco (1988) is being developed by an International Committee established by SCOR. It will include both invited and contributed papers. Exhibits of books and oceanographic equipment are also to be considered. Further information from: M. en C.

2.7. URSI CONFERENCE ON WAVE-INDUCED PARTICLE PREClPlTATlON AND WAVE-PARTICLE INTERACTIONS (URSI-WIPPS9)“’

Dunedin, New Zealand, 5 - 11 February 1989 The URSI-WIPP89 will be held from 5 to 11 February 1989 at the University of Otago, New Zealand. The Convener is R. L. Dowden and the Co-Conveners are H. Matsumoto and U. S. Inan. The proposed deadline for abstracts is 1 November 1988. The aim of this conference is to bring together investigators interested in magnetospheric wave-particle interactions and wave-induced particle precipitation effects, including interactions between electrons and whistler-mode waves, electrostatic and electromagnetic ion-cyclotron waves and ions, nonlinear electron and ion cyclotron wave growth, wave-particle-wave interactions such as ULF/VLF and VLF/VLF, the role of such interactions in the acceleration and loss of the radiation belt particles, ionospheric phenomena associated with wave-induced particle precipitation, and new techniques for measuring wave spectra and particle precipitation effects. This will be a conference of specialists to talk and interact with one another. There will be sufficient time and space to allow somewhat more papers than participants, so each can reasonably assume that he/she will be able to present one or more papers. Both oral and poster papers will be presented. If a large enough proportion of authors prefer posters, the preference of authors will determine the oral/poster ratio! At this early stage (May 1987) the conveners are open to suggestions about the policy and structure of the meeting. The Conference site will be at Knox College, one of the Residential Halls of the University of Otago, about 20 min walk from the centre of Dunedin. Sights (lakes, fjords, glaciers, etc.) are within a day’s drive. Full accommodation at Knox College, including all meals not paid for by the registration fee, will cost about NZS55 per day in 1989. Alternative accommodation in hotels and motels can be arranged if necessary. A mid-range motel convenient to the conference site will probably cost (room only) about NZS120 per day for two @‘Extract from URSI Information

persons (NZSlOS for single) in 1989. Cheaper accommodation can be found for families. Some low cost motels have full cooking facilities and sleep 4-6. Registration fee will be about NZ$200, but this includes abstract book, lunch, morning and afternoon tea/coffee each day, and the Conference Banquet-all for a little over US$lOO! Accomp~~ng persons will find much of interest in Dunedin and will pay only incurred expenses (e.g., Conference Banquet if attended). There will be financial help for some young scientists on application. Intending participants requiring further information, please write with your preference for Knox or motel: Professor R. L. Dowden, Physics Department, University of Otago, Dunedin, New Zealand. 2.8. THIRD AHS SCIENTIFIC ASSEMBLY

Baltimore, Maryland, USA, lo-19 May 1989 In recent times, the International Association of Hydrological Sciences (IAHS) has been convening scientific assemblies in the years between the quadrennial General Assemblies of the International Union of Geodesy and Geophysics (IUGG), of which IAHS is a component body. In response to an ~vitation from the US National Academy of Sciences and National Committee for IUGG, the International Association of Hydrological Sciences will sponsor its Third Scientific Assembly in Baltimore, Maryland, USA, from 10 to 19 May, 1989. Sessions on 11 to 12 May will be jointly sponsored by IAHS, the International Association of Meteorology and Atmospheric Physics (IAMAP), and the American Geophysical Union (AGU). The latter organization will be holding its annual spring meeting at the same location between 8 and 12 May. The programme during the following week will be sponsored only by IAHS. The Assembly is likely to have cosponsorship support from UNEP, UNESCO and WMO, as well as a number of USA Federal agencies. Other international and national societies are expected to be cooperating organizations. The Third Scientific Assembly will provide an interdisciplinary forum for review of the latest developments in the field of hydrology. A series of symposia and workshops will bring together international specialists in hydrology and related sciences to present results of research and practice, to create an opportunity for interaction between representatives of the various Commissions and Committees, and to point the way to needed research for the future. The programme will consist of eight Commission/Committee-sponsored symposia covering essentially all phases of the hydrologic cycle: 28
