EGU session announcement: Interactions among biology, structure and processes in sea-ice
We would like to draw your attention to the session "Interactions among
biology, structure and processes in sea-ice" (CR9.20 and co-listed in
BG7), which will take place at the upcoming European Geoscience Union
General Assembly in Vienna, 22-27 April 2012.
Abstracts can be submitted via http://meetings.copernicus.org/egu2012/ Submission deadline is 17 January 2012.
CR9.20 (co-listed in BG7)
Interactions among biology, structure and processes in sea-ice
Maddalena Bayer-Giraldi, Marcela Ewert
Abiotic processes like sea-ice formation and consolidation, brine and
nutrient dynamics, and seasonal ice melt, together with factors such as
brine-channels structure, temperature and salinity, shape the biological
communities within the ice. Organisms have developed a series of
mechanisms to cope with these conditions, of which the production of
exopolymeric substances and antifreeze proteins are some examples.
However, biological activity is in turn shaping its environment.
Physical properties like sea-ice microstructure, porosity and
permeability are influenced by biology. The presence of organisms also
affects chemical processes within ice.
We encourage the submission of contributions regarding sea-ice biology
and physical properties, as well as biological and chemical processes
within the ice and in ice-related environments, with a focus on the
interaction among them. The session welcomes contributions about sea-ice
and sea ice-influenced waters.
