Special Sessions at Hawaii 2006 Ocean Sciences Meeting: Carbon Cycling...and
Equatorial Physics...
#1 We would like to bring your attention to a special session (OS009)
on "Advances in the Study of Carbon Cycling on Continental Margins"
for the 2006 Ocean Sciences Meeting in Honolulu Hawaii, 20-24 February
2006. The session description is included below and can be found
on the meeting's website at http://www.agu.org/meetings/os06/. The
online abstract submission deadline is 20 October. OS009: Advances
in the Study of Carbon Cycling on Continental Margins Description:
In the post-JGOFS/post-WOCE era, paradigms and models of ocean carbon
biogeochemistry and of the ocean's role in the global carbon cycle
derive primarily from high-quality data collected in the deep sea.
Unfortunately, because of our limited understanding of the processes
regulating the flux and biogeochemical transformation of carbon
in coastal and shelf environments, the geographical boundary constraints
imposed in ocean carbon models reflect as much what we do not know
about ocean margin processes as what we do. In this session we will
bring together members of the research community who are currently
making inroads into the study of carbon cycling in the complex neritic
environment. Topics especially appropriate for this session include:
carbon flux between land, shelf waters, open ocean, and troposphere;
coupled biogeochemical cycles and ecosystem dynamics regulating
carbon turnover on shelves; carbon sedimentation, benthic-pelagic
coupling, and burial; impact of fossil organic and inorganic carbon
on local carbon dynamics; drainage basin and groundwater inputs;
methods for studying spatial and temporal variability in carbon
fluxes and turnover nearshore; and the design of in situ and remote
observing systems suitable for characterizing carbon dynamics nearshore
and in open shelf environments.

#2 OS061: Equatorial Physics, Air-Sea Interaction and Biogeochemistry
This
session seeks to address both traditional and emerging issues in
tropical oceans related to the equatorial physical oceanography,
tropical ocean-atmosphere interactions, and biogeochemistry of the
equatorial Pacific. New moored observations have been started in
the Indian Ocean and the PIRATA array is due to be enhanced in the
Atlantic. Results from new high-resolution general circulation models
will also be useful to augment spatial and temporal limitations
of observations. Therefore, this session encourages submission of
new studies on the dynamics of tropical ocean circulations, including
papers on intraseasonal oscillations, the Indonesian throughflow,
interactions between the tropical and higher latitude oceans (the
Subtropical and deeper overturning cells, origin of tropical water
masses, etc.), seasonal-to-interannual variability, and near-equatorial
processes (deep equatorial jets, subsurface countercurrents, and
equatorial inertial instability, etc.). Tropical ocean-atmosphere
interactions give rise to modes of climate variations. Besides the
advancement in the understanding of El Nino/Southern Oscillation,
there are recent developments in exploring coupled variabilities
of the Indian Ocean dipole and the Atlantic zonal mode. While ocean
planetary waves and surface heat flux are shown to play an important
role in organizing coupled modes, the importance of several additional
ocean processes are also being recognized, such as salinity and
the subtropical cells. Papers are invited to discuss these new perspectives
of ocean-atmosphere interactions, tropical climate modes, predictability
and their impact on global climate and society. The equatorial Pacific
Ocean is recognized as the largest natural oceanic source of CO2
to the atmosphere. The interannual variability of equatorial upwelling
influences biological processes and carbon cycling. In addition,
the deliberate iron fertilization of surface water in this high-nutrient,
low-chlorophyll area has resulted in phytoplankton growth and a
decrease of surface pCO2. This session invites presentations on
all aspects of biogeochemistry of the equatorial Pacific Ocean,
especially highlights of recent field observations and physical-biogeochemical
modeling results.
