Those who wish to present paper(s) at the Symposium are requested to submit an Abstract (longer than 20 lines - maximum 500 words) of each proposed paper by e-mail latest by 30 November 2003. In the submission authors must indicate at least one topic (using the tentative numbers indicated in front of the subjects above) which is thought to be most appropriate and to state their preference of oral or poster presentation. However, the Scientific Program Committee may change/rearrange submitted papers to other sessions than author's preference in order to accommodate the overall oral/poster program sessions.

In principle the Local Organizing Committee (LOC) will accept Abstracts as ASCII text format only by E-mail (In exceptional case, those who have some troubles to use E-mail system can send a copy of Abstract in a diskette by mail to LOC). The Abstracts will be used to review the paper suitability for oral or poster presentation to an appropriate session. Therefore, it is in authors' own interest to prepare the Abstracts with sufficient information for their review by the Scientific Program Committee. It should be noted that a short Abstract, for example with less than about 20 lines of text, would end up in a wrong session or be deprived of oral presentation.

The Abstracts should include all of the followings:

1. Title of the Abstract
2. Author Listing (principal author first): Family (last) name, Middle name (initial), Given (own) name
3. Affiliation
4. Abstract text: Maximum 500 words (more than 200 words recommended)
5. Indicate your preference to "Oral" or "Poster" presentation
6. Details of correspondence: Name, Mailing Address, Phone, Fax, E-mail

Abstracts should be sent to the Chairman of LOC by e-mail to ozone2004@geol.uoa.gr
