Gordon Research Conference Applications

10 September 1998

Dear Colleague,

This is to inform you that the applications for the 1999 Gordon Research
Conference (GRC) on Polar Marine Science are now open. You will find,
below, the scientific program of the Conference. As you will see from the
list of session topics and lecture titles, and also from the names of
Discussion Leaders and Speakers, the discussions on the controls and
significance of carbon fluxes in polar seas should be most exciting.

If you are interested in attending the GRC, I recommend that you apply as
soon as possible. Because all GRCs are limited to a maximum number of 135
participants, including the Discussion Leaders and Speakers, we may be
unable to accept late applicants.

The application procedure is as follows:

1. Go to the GRC WEB site, at http://www.grc.uri.edu/.

2. On the front page, click: Attending a Conference.

3. On the page "Attending a Gordon Conference", click: On-Line Application.

4. Follow the instructions and fill all the boxes.

- The name of the Conference is: Polar Marine Science
- The location is: Ventura
- The date is: 7-12 March 1999

5. You will receive an answer from the GRC Office within a few weeks after
applying (the processing of applications will start in mid-September).

6. Once your application is accepted, you must register. The cost of
registration, which includes the room and meals from the afternoon of
Sunday 7 March through the morning of Friday 12 March, will be US$630
before 14 February 1999 and US$680 after that date. These rates are for a
double room, to be shared with another participant. Single rooms are
available, at the cost of US$725 (or US$775 for registration after 14
February). All participants must attend the Conference for its full
duration. Guests are allowed, at a reduced registration fee. No guests or
children are allowed in the lecture room.

I look forward to seeing you in Ventura, this coming March.
