General Information
2000 Western Pacific Geophysics Meeting
National Olympic Memorial Youth Center (NYC)
Shinjuku, Tokyo, Japan
June 27-30, 2000
(Tuesday through Friday)

Introduction The WPGM in 2000 will overlap with the annual meeting of the Japanese Association of Earth and Planetary Science Societies (JAEPSS), which is a gathering of about 2,000 Japanese scientists. This overlap provides many opportunities for individual and group collaboration between scientists and students that might not otherwise be possible. The meeting facility for WPGM and some housing accommodations will be shared with JAEPSS. Some logistics for the WPGM will be different from previous meetings because of the overlap with JAEPSS and the rules of the meeting facility.

For these reasons, the registration fee will be lower than for past WPGM meetings. Some housing, equivalent to university dormitories, will be available at the Youth Center for about $90 to $120 for the week. Meals at the Youth Center are affordable and will require advance purchase. Meals in restaurants close to hotels and inside the subway are affordable but credit cards are rarely accepted. A selection of hotels with a range of rates will also be available. Those staying in hotels will have about a 10-minute train ride to the meeting facility. Walking to and from the hotels to the meeting facility will take about 25-30 minutes. Watch for additional information about this meeting on the AGU homepage!

Sponsors American Geophysical Union (AGU) is a society of over 35,000 members in 130 countries with purposes of advancing progress in the Earth, atmospheric, oceanic, hydrologic, and space and planetary sciences. AGU is dedicated to fostering high-quality scientific research, disseminating the results of that research, enhancing educational opportunities in science, and encouraging international cooperation in geophysics.

Local Sponsors

1. General Information With submission of your abstract to the 2000 Western Pacific Geophysics Meeting, you agreed to present your paper on the day, time, and in the mode of presentation assigned by the Program Committee. You have been assigned to an ORAL session at the time listed on your acceptance letter; this cannot be changed.

Schedule times given in the abstract volume are subject to change without prior notice. Check the At-Meeting Program and the Addendum for any program changes.

2. Your Presentation Contributed papers will have 10 minutes for presentation, plus 5 minutes for the discussion and changeover time, for a total of 15 minutes. Some invited papers will have 15 minutes for presentation and 5 minutes for discussion, for a total of 20 minutes. Session presiders will hold you to this time.

Cover the same material as reported in the abstract.

Write your talk in advance so that your ideas are logically organized and your points clear. At the very least, write a detailed outline of your presentation. Cover only the few essential main points, and leave the details for your publication.

Rehearse. If possible, give your talk to one or more colleagues, and ask them for suggestions for improvement. If the talk runs longer than the allotted time, eliminate the least essential material and rehearse again.

Give an opening statement to acquaint the audience with the nature and purpose of the study.

Speak slowly and clearly. Word choice should be simple: Use active words, short sentences. Words should reinforce visual material.

Out of consideration for the other speakers and the audience stay within your allotted time. This is essential to ensure adequate time for questions and discussion and adherence to schedule. An electronic speaker timer will help you keep track of time.

Use the public address system and speak into the microphone toward the audience at all times. When using the lavalier microphone clipped to your lapel, if you turn your head away from the microphone it may be difficult for the audience to hear you. If you need to see what is being shown on the screen, have pictures or copies at the speaker's rostrum.

3. Slide and Viewgraph Preparation Slides and viewgraphs must be well designed, simple, and readable by everyone in the audience. It is worthwhile to use professional preparation services, if available.

Use as few slides and viewgraphs as are really needed and can be discussed in the time allotted. As a general rule, one for each 1 or 2 minutes of presentation is all that will be effective.

Devote each slide and viewgraph to a single fact, idea, or finding. Illustrate major points or trends, not detailed data. Do not show long or complicated formulas or equations. Each slide should remain on the screen at least 20 seconds.

Use the absolute minimum number of words in title, subtitles, and captions. Remember that standard abbreviations are acceptable.

Use bold characters. Do not use fancy serifs. A rule of thumb for the minimum height of readable lettering (size) is 3 millimeters on finished slides. Do not make slides from illustrations or tables that were prepared for publication. They are rarely satisfactory. A good way to test your material is to stand away 1 foot for every inch of original copy width. If you can't read it from that distance, then your audience will not be able to read it either when it is projected.

Table Preparation: Do not use more than three or four vertical columns; six to eight horizontal lines. Any more and the information will not be readable. Do not use ruled vertical or horizontal lines. They distract the eye and clutter the slide. Whenever possible, present data by bar charts or graphs instead of tables. Colored graphs are very effective.

Graph Preparation: Generally, do not use more than one or two curves on one diagram; three to four as maximum but only if well separated. Label each curve; do not use symbols and legend. Do not show data points unless scatter is important.

Color adds attractiveness, interest, and clarity to slide and viewgraph illustrations and should be used whenever possible. If you use color, remember that contrasting colors are easier to see.

Use 2" x 2" paper or plastic mounted slides, designated for a 35mm slide projector. Be sure that they are clean and in good physical condition.

Critically examine every slide and viewgraph, and try out the entire set under adverse light conditions before using them at a meeting. It is sometimes impossible to provide excellent light conditions at meetings.

Mark a large positioning dot or make a notch in the lower left hand corner of each slide when it is laid flat so it may be read; rotate 180o for loading into a carousel. A notch makes it easy to see that all slides are in correct position in a tray. Number every slide in proper sequence, as you wish them shown. This is important, because slides may be dropped or become disarranged.

An introductory and concluding slide and viewgraph can much improve the focus of your talk.

4. Audio Visual Equipment Each oral meeting room will be equipped with one 2" x 2" (35mm) slide projector, two overhead (viewgraph) projectors, an electric pointer, and one screen.

If you would like to preview your viewgraphs, you may use one of the overhead projectors set in a meeting room during the lunch break from 1230 hr-1330 hr.

Questions about AV equipment should be directed to the AGU staff at the AGU Facilities Desk, located in the NYC Building, Room 103.



1. General Information With submission of your abstract to the 2000 Western Pacific Geophysics Meeting, you agreed to present your paper on the day, time, and in the mode of presentation assigned by the Program Committee. You have been assigned to a POSTER session; this cannot be changed.

Schedule times given in the abstract volume are subject to change without prior notice. Check the At-Meeting Program and the Addendum for any program changes.

2. Poster Preparation Place the title of your paper prominently at the top of the poster board to allow viewers to identify your paper easily. Indicate 1) the presentation number of the abstract, 2) title, and 3) author(s) names. Highlight the authors' names and address information, in case the viewer is interested in contacting them for more information.

Prepare all diagrams or charts neatly and legibly beforehand, in a size sufficient to be read at a distance of 5 feet. Type should be at least 1 inch (2.5 cm) high. Use creativity by using different font sizes and styles, perhaps even color. Double-space all text. Use different colors or textures for each line or bar contained in your graph or chart.

Organize the paper on the posterboard so that it is clear, orderly, and self explanatory. You have complete freedom in displaying your information in figures, tables, text, photographs, etc. The presentation must cover the same material as the abstract. Label different elements as 1, 2, 3, or A, B, C. This will make it easier for a viewer to easily follow your display.

Include the background of your research, followed by results and conclusions. A successful poster presentation depends on how well you convey information to an interested audience.

3. Your Presentation Poster sessions will be held at the National Youth Center in the International Exchange Building.

To locate your assigned posterboard, look for the board with your paper number on it. A diagram will be posted at the AGU Facilities Desk, and staff will be available to direct you to your posterboard.

All posters should be placed on the posterboards between 0900 hr-0930 hr on the day of your presentation. Posters must remain up the entire day. Posters must be removed by 1800 hr. Posters remaining after 1800h will be removed by AGU and placed on the floor directly beneath the board. AGU will not be responsible for posters and materials left on poster boards after the stated hours.

Place your poster on the side of the posterboard that is marked with your paper number. Dimensions of the useable work area are: 90cm WIDE by 210cm HIGH.

You are required to be present at your board for at least one hour during your scheduled presentation time. Presenters of A.M. sessions should be present between 0945 hr-1145 hr; presenters of P.M. sessions should be present between 1500 hr-1700 hr. Leave a message on your board detailing the hours you plan to be at your presentation. After the session, leave a note on your posterboard as to where you can be reached, in case someone wishes to discuss your research further.

4. Audio Visual Equipment and Internet Access Due to space limitiations at the Facility, audio-visual (AV) equipment and internet access are not available for poster presentations.

5. Facilities Desk The AGU Facilities Desk will be located in Room 103 in the National Youth Center. AGU staff will be available to assist you.

Thumbtacks, pushpins, tape, and scissors will be available. Additional supplies may be available, however, if you have special needs for your poster presentation, we suggest you bring those supplies with you to the meeting.


Session Chair Guidelines Oral Session Chairperson's Guidelines
1. Please check the program and addendum for any changes or updates to your session.

2. The session must stay on schedule so that individuals who are presenting a paper or individuals who wish to hear a specific talk may do so without concerns of time. An electronic speaker timer is provided in each room to alert the speaker when time is running out. You may use any reasonable means to stop a speaker who has exceeded the assigned time allotment.

3. If a paper has been withdrawn or the speaker does not appear, you may either call for discussion of previous papers in that session or call a recess, but you may not change other presenters' times. Please record any no-show authors on the Session Evaluation Form.

4. Familiarize yourself in advance with the pronunciation of the speakers' names and state the author's affiliation when introducing speakers. This information is published in the abstract volume.

5. You may need to interrupt speakers in order to ask them to speak more audibly, slowly, or clearly; speak into the microphone; face the audience; or briefly explain the message of an illegible slide or transparency.

6. The chairperson, not the speakers, conducts the discussion by recognizing participants on the floor. Make sure that during discussions, participants stand up, identify themselves and speak loudly and clearly so the audience can hear the questions as well as the replies. For larger sessions it may be helpful to ask the speaker to repeat questions into the microphone before answering.

7. If a paper draws no questions from the floor, you are encouraged to ask questions in an attempt to stimulate discussion, if time allows. On the other hand, some papers elicit more than the usual number of comments, so judge accordingly.

8. To maintain the schedule it may be necessary to defer lengthy discussions to the end of the session or to suggest that the discussion be continued in private, once the session has ended.

9. No new presentations may be added to the session.

10. Complete an evaluation form for your session and return it to AGU. A copy will be placed in your session room. Extra copies will be available on-site at the AGU Facilities Desk located in Room 103.

Poster Session Chairperson's Guidelines
1. Please check the program and addendum for any changes or updates to your session.

2. Arrive in the poster area at least one-half hour before the session is scheduled to start.

3. Make sure that authors' poster boards are numbered properly.

4. Make sure that authors are beginning to set up their papers and are having no problems.

5. Make sure that authors have posted their "attendance" time on their poster board number and the time reflected is within the appropriate AM or PM session period.

6. Help any author who is having trouble with layout, setup, or equipment.

7. Encourage participation by introducing persons in the area to specific authors and attempt "crowd control" if necessary.

8. Record on the evaluation form attendance at different times during the session.

9. No papers may be added to the session. No papers may be moved from one session to another or to another posterboard. Record any such situations on the evaluation form.

10. Should any problem develop with poster set-up, contact an AGU staff person located at the Facilities Desk in Room 103.

11. Complete an evaluation form for your session and return it to AGU. Extra copies will be available at the AGU Facilities Desk.


Program This meeting is intended to serve the needs of geophysicists interested in studies in the western Pacific region, but papers on all related aspects of geophysical sciences are encouraged. The meeting will be organized similar to AGU's annual meetings held in the United States.

The Western Pacific Geophysics Meeting is open to geophysicists worldwide without regard to nationality of society membership. You should not miss this unique opportunity to gather with your colleagues. The meeting venue for the 2000 WPGM will be the National Olympic Memorial Youth Center in Shinjuku, outside of Tokyo.

General Information Climate Tokyo's climate is subtropical, with an average annual temperature of 76-80 Fahrenheit during the day and 66-71 Fahrenheit in the evenings. Japan's rainy season, called tsuyu or baiu, is caused by the seasonal rain front, which stays above Japan between tropical high pressure and Siberian cold high pressure. Tsuyu usually starts in early June and ends in middle July except in the Hokkaido region. Although tsuyu is a gloomy time, the rain is very important for rice cultivation. Also, there are many pretty flowers blooming at this time. In general, visitors should wear lightweight clothing in late June and be prepared for rain showers.

Language The official language for the WPGM will be English.

Currency Only Japanese yen(\) is acceptable at regular stores and restaurants. Certain foreign currencies and credit cards may be accepted at a limited number of hotels, restaurants, and souvenir shops. You can buy yens at foreign exchange banks and other authorized money exchangers on presentation of your passport.

Traveler's Checks and Credit Cards Traveler's checks are accepted only by leading banks and major hotels. The use of traveler's checks in Japan is not as popular as in some other countries. Visa, MasterCard, Diners Club, and American Express are widely accepted at hotels, department stores, shops, restaurants, and nightclubs.

Electrical Appliances and Water Japan operates on 100 volts for electrical appliances. The frequency is 50 Hz in eastern Japan including Tokyo and 60 Hz in western Japan including Kyoto and Osaka. Drinking water served at hotels and restaurants is safe for visitors.

Shopping Business hours for most stores are from 10:00hr to 19:00hr. They are open generally on Sundays and national holidays.

Tipping In Japan tips are generally not necessary, since a 10-15% service charge is added to the bill at hotels and most restaurants.

Insurance Coverage Participants traveling from the U.S. may wish to purchase accident and medical insurance protection during their visit to Japan. Seabury and Smith, an association service organization, offers coverage for international travel. Insurance must be purchased for a minimum of 15 days, up to a maximum of 60 days. Prices will vary depending upon the individual's age and choice of benefit package. For more information, contact Seabury and Smith at +1-202-457-6842.
