IMPORTANT DPS MEETING UPDATE

MONTEREY AQUARIUM BANQUET TICKETS - BUY THEM NOW

Tickets to the DPS Banquet event at the Monterey Aquarium, Sponsored by
Ball Aerospace, are selling fast.  The number of tickets available is
limited to a total of 350 at the rate of $35 regular and $25 student.

The cutoff date for purchasing a banquet ticket is Thursday August 28
-- BEFORE the start of the meeting.

NO BANQUET TICKETS WILL BE SOLD AT THE MEETING.

You may purchase your ticket now as part of the registration process.
If you have already registered, but now wish to order a banquet ticket,
you may do so by downloading the form:

http://www.aas.org/divisions/dps/regform.pdf

and just make a note "already registered, adding banquet ticket",
circle only banquet.

NASA KECK APPLICATIONS DUE

Applications are due on 12 September for NASA time on the Keck
telescopes for the period February 2004 - July 2004.  The NASA time is
focused on the discovery and characterization of planetary systems and
investigation of their origin and evolution.  Telescope time will be
awarded within three discipline areas: detection of extrasolar planets,
origin and nature of planetary systems, and investigation of our own
solar system.  The proposal process is now being handled by the
Michelson Science Center at Caltech.  Please see the new website at
http://msc.caltech.edu for further information.  Observers will receive
financial support for travel to the W.M. Keck Observatory.

Session U09 - Evolution of Biogeochemical Cycles

In the absence of coupled biogeochemical cycles, life (as we know it)
can neither originate nor persist on any planet, yet we do not
understand how biogeochemical cycles develop and evolve. This session
will provide a forum for understanding how biogeochemical cycles
evolved on Earth and how to use that knowledge to search for evidence
of past or present life on other planets and to explore the future of
life on Earth. Although we have detailed knowledge of numerous
physicochemical and biochemical processes, we do not understand how
many key metabolic processes, such as nitrogen fixation, oxygenic
photosynthesis, aerobic respiration, and anaerobic metal and sulfate
reduction, coevolved to form interactive biogeochemical cycles on a
planetary scale. At the heart of this enigma is our ignorance of the
rules of biochemical evolution that govern how energy conversion
between coupled chemical processes evolved to become "living" organisms
and of the mechanisms of the major transformations in the history of
both life and the biosphere. Moreover, on Earth, several biogeochemical
cycles have been markedly altered by human activities over the past 200
years. As we drift further away from the biogeochemical domain that
characterized Earth prior to human perturbation, we must understand how
biogeochemical cycles interact with each other and other planetary
processes to maintain a habitable planet. This session will encourage
dialogue among scientists with expertise in molecular evolution,
microbial ecology, biogeochemsitry, and planet formation.
