In the L' Aquila Quadrennial Symposium (1996) the IO3C adopted a new policy for the final manuscripts for this Symposium in order to provide extended abstracts at the time of the Symposium and to give possibility to the authors to submit full size papers to international journals. Each author will be requested to prepare a camera-ready manuscript (Extended Abstract) of 2 full pages in JGR format including figures, tables, and references for each presentation. The camera-ready manuscript must reach the LOC before 30 April 2004. If an Extended Abstract is found not to be of acceptable standard, it may not be included in the Proceedings.

LOC is planning to print and distribute the Proceedings to all of the registered participants at the time of Symposium?????. Some extra copies for interested scientists and libraries will be available at cost of printing. Information on preparing a final manuscript is given on the Web site??????.

Those authors who fail to submit 2-page camera-ready extended abstracts by 30 April 2004 will be excluded from the Final Program of presentations. The extended abstracts by authors who do not attend the Symposium would not be included in the Proceedings. LOC will strictly check if at least one of the authors has completed his/her registration by 30 April 2004.
