  1. CL2.17 - Physical and Biogeochemical Feedbacks in the Climate
    System

  1. CL2.17 - Physical and Biogeochemical Feedbacks in the Climate
    System

Organizers of Session CL2.17, "Physical and Biogeochemical Feedbacks in
the Climate System," announce a call for abstracts. This session will be
convened at the EGU (European Geosciences Union) General Assembly 2011,
scheduled for 3-8 April 2011 in Vienna, Austria.

The aim of the session is to present recent research and promote
discussion relevant to feedbacks within the climate system (relevance to
future climate change is particularly welcome, but not essential). Both
physical and biogeochemical feedbacks are expected to feature
prominently in the session.

Organizers particularly welcome abstracts on the following possible
topics:

- Cloud feedbacks;
- Ice-albedo feedbacks;
- Other polar amplification mechanisms;
- Hydrological feedbacks;
- Carbon cycle feedbacks;
- Vegetation and/or land-use change feedbacks;
- Ocean circulation feedbacks; and
- Other biogeochemical feedbacks such as ocean DMS production,
terrestrial nitrogen cycling, dust production, and feedbacks
involving atmospheric chemistry.

Observational and modeling studies are equally encouraged, with modeling
studies expected to span the range of model hierarchy from simple models
to EMICs to coupled-GCMs.

Abstract submission deadline: Monday, 10 January 2011.

  1. CL2.4/OS2.4 - Fjords

Organizers of Session CL2.4/OS2.4, "Fjords," announce a call for
abstracts. This session will be convened at the EGU (European
Geosciences Union) General Assembly 2011, scheduled for 3-8 April 2011
in Vienna, Austria.

Marginal marine environments, such as fjords, act as natural sediment
traps and typically have high sediment accumulation rates, providing the
potential for high-resolution palaeoclimatic and palaeoenvironmental
studies on decadal to centennial timescales and presenting a unique
opportunity to study land-ocean interactions.

This session solicits contributions that present new insights to the
understanding of fjordic processes, with a particular focus on climate
and environmental records from fjords (past and present). Organizers
welcome both model and data-based contributions that address fjordic
processes, including:

- Physical oceanography;
- Sedimentology;
- Geophysics;
- Palaeo-biology/ecology; and
- Palaeoclimate reconstructions.

Abstract submission deadline: Monday, 10 January 2011.

  1. CR9.10 - Sea Ice and Sea Ice-Climate Interactions

Organizers of Session CR9.10, "Sea Ice and Sea Ice-Climate
Interactions," announce a call for abstracts. This session will be
convened at the EGU (European Geosciences Union) General Assembly 2011,
scheduled for 3-8 April 2011 in Vienna, Austria.

In 2010 the summer sea ice extent was the third lowest in satellite
history. Although the amount of young multiyear ice has increased
somewhat in the last couple of years, the amount of thick multiyear ice
has continued to decline. Some climate models predict that summer arctic
sea ice might altogether disappear in about 30 or 40 years. While the
effects of a shrinking sea ice cover on global climate, ocean
circulation, and marine biology are expected to be significant, they are
difficult to evaluate because of our incomplete understanding of the
polar climate components and our limited ability to model them.

The scientific community is investing considerable effort in organizing
our current knowledge of the physical and biogeochemical properties of
sea ice, exploring poorly understood sea ice processes, and forecasting
future changes of the sea ice cover.

In this session, organizers invite contributions regarding all aspects
of sea ice science and sea ice-climate interactions. Oral presentations
and posters on snow and sea ice thermodynamics and dynamics, sea
ice-atmosphere and sea ice-ocean interactions, sea ice biological and
chemical processes, and sea ice models will be welcome.

Abstract submission deadline: Monday, 10 January 2011.

  1. GD1.4 - Polar Heatflow: Geology, Ice Sheets, and Climate

Organizers of Session GD1.4, "Polar Heatflow: Geology, Ice Sheets, and
Climate," announce a call for abstracts. This session will be convened
at the EGU (European Geosciences Union) General Assembly 2011, scheduled
for 3-8 April 2011 in Vienna, Austria.

Heatflow from the Earth's interior in the polar regions is poorly known
and there is an urgent need to improve understanding of its rates and
distribution. It can provide information about large-scale crustal
structure and geological processes; ice sheet stability and response to
climate change; distribution of basal ice melting, the development of
sub-ice hydrology, subglacial lakes, and enhanced glacial flow in ice
streams; areas likely to preserve old ice suitable for coring to push
ice core records back in time; and stability of methane hydrates.
Thermal gradient measurements can provide climatic information. This
session proposal seeks to invite submissions on direct measurement and
indirect estimates of heatflow in the polar regions.

Abstract submission deadline: Monday, 10 January 2011.
