Biogeochemistry of Dissolved Organic Matter in the Arctic Ocean
Session 040, 2012 Ocean Science Meeting
20-24 February 2012
Salt Lake City, Utah

Organizers of session 040, "Biogeochemistry of Dissolved Organic Matter
in the Arctic Ocean" announce a call for abstracts. This session is
organized within the Chemical Oceanography, Aquatic Chemistry category
at the 2012 Ocean Sciences Meeting, which will be convened 20-24
February 2012 in Salt Lake City, Utah.

The major sources of dissolved organic matter (DOM) to the Arctic Ocean
are riverine input, inflow from the Atlantic and Pacific Oceans, and
autochthonous production in surface waters and shelf seas. Rapid climate
change in the region is currently shifting the balance of these sources.
As they each supply DOM with different chemical characteristics we can
expect that the turnover and fate of this material will also change.
Shifts in the bioavailability will influence the role that DOM plays in
arctic marine ecology and biogeochemistry. Increased supply of colored
DOM (CDOM) will affect photochemistry, underwater light penetration and
quality, and heat absorption. Studying the nature, distribution, and
source dependency of the persistent refractory fraction of DOM offers an
additional tool to assess current and future circulation patterns. This
session invites contributions on any of these aspects of arctic DOM
biogeochemistry.

The abstract submission deadline is 11:59 p.m. Central Daylight Time
Friday, 7 October 2011 (4:59 a.m. Greenwich Mean Time Saturday, 8
October 2011). For complete instructions regarding online registration

The Southern Ocean and its Role in the Climate System
Session 004, 2012 Ocean Science Meeting
20-24 February 2012
Salt Lake City, Utah

Organizers of session 004, "The Southern Ocean and its Role in the
Climate System" announce a call for abstracts. This session is organized
within the Chemical Oceanography, Aquatic Chemistry category at the 2012
Ocean Sciences Meeting, which will be convened 20-24 February 2012 in
Salt Lake City, Utah.

Over the past decade, the climate dynamics, biogeochemistry, and
physical oceanographic communities have highlighted the Southern Ocean
as a key player in the climate system. Thus, understanding the processes
that shape the Southern Ocean mean state, variability, and response to
external forcing is essential for our understanding of the climate
system as a whole. Data collections have expanded significantly over the
past decade, and modeling efforts have advanced through Earth System
Model development, data assimilation solutions, and process models.
These new developments require investigation of how (or whether) the
representation of the Southern Ocean has been improved using a
combination of model-model and model-data comparisons.

The goal of this session is to present modeling and/or data efforts that
investigate all aspects of the Southern Ocean, including its mixing and
mesoscale processes, large-scale circulation, ocean-atmosphere and
ocean-ice interactions, and biogeochemical processes. Organizers
particularly encourage analyses using models for the upcoming IPCC Fifth
Assessment Report and assimilated models.

Improved Projections and Forecasts from Climate and Weather Models
Session 2.5.5, IPY 2012 From Knowledge to Action
22-27 April 2012
Montreal, Canada

Organizers of session 2.5.5, "Improved Projections and Forecasts from
Climate and Weather Models" announce a call for abstracts. This session
will be convened at the IPY 2012 From Knowledge to Action conference,
scheduled for 22-27 April 2012 in Montreal, Canada.

The importance of climate change in the polar regions is well known.
Yet, the complexity of the polar climate system and the lack of
consistent, long-term observations have limited our progress in
understanding this critical and fast changing region of the earth. The
lack of observations coupled with the threat of changes to the
high-latitude environment makes improving our ability to model the
weather and climate of polar regions extremely urgent. Improving our
modeling capability requires synthesis of our knowledge of important
physical processes from weather to climate scales and an evaluation of
how well they are represented in state of the art climate and weather
models. Challenges facing modelers range from providing accurate
short-term forecasts of hazardous weather, such as polar lows and
extreme winds, to improving long-term projections of climate change and
separating the anthropogenic signal from natural variability.

This session will focus on advances in climate and weather modeling in
the polar regions that took place during the International Polar Year
(IPY) 2007-2008 and advances in polar modeling that have occurred as a
result of IPY activities. Presentations are invited on weather and
climate modeling on all time scales, for both the Arctic and Antarctic.
Presentations that discuss modeling advances resulting from IPY
observational campaigns are encouraged, as are presentations that
discuss the application of polar models to understand the physical
processes acting in the polar climate system.

The abstract submission deadline is 11:59 p.m. Eastern Standard Time
Friday, 30 September 2011. For further information on abstract
submission, please go to:

Past, Present, and Future Polar Climate Change
Session 2.2.6, IPY 2012 From Knowledge to Action
22-27 April 2012
Montreal, Canada

Organizers of session 2.2.6, "Past, Present, and Future Polar Climate
Change" announce a call for abstracts. This session will be convened at
the IPY 2012 From Knowledge to Action conference, scheduled for 22-27
April 2012 in Montreal, Canada.

The International Polar Year 2007-2008 took place during a period of
extraordinary climate change in polar regions. Many IPY projects
investigated both the status of polar environments, and polar changes
and their causes. Rapid polar change continues. This session will focus
on the synthesis of the results from the IPY projects and from
subsequent investigations that grew from IPY projects. The session is
particularly concerned with multidisciplinary aspects of polar climate
change; with links between the north and south; and with feedbacks in
the climate system. It will include:

- Studies of past polar climates that encompass all earth systems
and that inform the present and the future state of the Arctic and
Antarctic, using all available knowledge; and
- Projections of future climate at the poles, particularly as they
guide understanding of the impacts on the various systems covered in
the sessions of Area 1 and as they enable us to meet the
requirements of policy makers.
