IPY-Oslo 2010 Session on Carbon Cycling and Acidification in Polar Regions

Dear colleagues,

We would like to bring to your attention to a carbon cycling and
acidification session at the 2010 International Polar Year meeting in
Oslo, Norway (8-12 June 2010):

Session T1-6: Arctic and Antarctic marine chemistry: The role of the
polar oceans in global carbon cycling and acidification

Please find a short session description below, and feel free to
distribute this email broadly.

T1-6: Arctic and Antarctic marine chemistry: The role of the polar
oceans in global carbon cycling and acidification

The polar oceans are believed to play a critical role in the global
uptake and transport of carbon dioxide (CO2), and are currently
experiencing significant climate change.  Recent acceleration in the
loss of Arctic sea ice has been shown to boost marine primary production
and increase the Arctic Ocean sink for atmospheric CO2. Meanwhile, an
increase in the intensity of the Southern Hemisphere mid-latitude
westerly winds has been linked to a weakening of the Southern Ocean CO2
sink.  Furthermore, anthropogenic ocean acidification and
climate-related changes have lowered the aragonite saturation state in
polar oceans and are likely to create conditions detrimental to
high-latitude ecosystems over the next century. It is critical to
understand how the polar oceans are responding to climate change and to
predict how their carbon chemistry will evolve under increased
greenhouse gas forcing.  This session will provide a venue to present
and discuss recent advances and discoveries in the carbon cycling of
polar oceans, the impact of climate change on carbon uptake and
transport in these regions, and the implications of these findings for
marine calcifying organisms.  We welcome studies on all aspects of
carbon cycling and acidification in the polar oceans and seas.
