Abstract submissions are now being accepted for session OS4, "High
Latitude Changes in Ocean, Ice and Climate," to be convened at the
European Geophysical Union (EGU) General Assembly 2009, being held 19-24
April 2009, in Vienna, Austria. The abstract submission deadline for
this and all other sessions is Tuesday, 13 January 2009.

Session Description:
The polar regions have raised considerable scientific interest, due to
recent rapid changes and multi-decadal scale variability. The arctic
summer sea ice is shrinking in extent and thickness. An increasingly
warm inflow of Atlantic water into the Arctic has been observed. Trends
in the Antarctic are less clear, but a dynamic range of changes, such as
disintegration of icebergs, warming in certain peripheral areas, and
cooling in the pole region have also been observed. Large-scale
circulation changes may be responsible for these observed changes, but
the connection to ongoing global warming is unclear.

An integrated understanding of the ongoing and future changes in high
latitudes requires field observations as well as further advanced
modeling capabilities. Model development greatly benefits from
observation, and models can help optimize observational campaigns. The
IPY has lead to a focused research effort in the polar oceans with large
programs such as DAMOCLES, SEARCH, and others, integrating
observation-modeling efforts.

For this session, presentations on processes in ocean, atmosphere, and
ice affecting the Arctic or Antarctic Oceans are encouraged. Of
particular interest are studies on a decadal scale with respect to
recent extremes, as well as studies attributing polar changes to the
large scale. Observational studies and results from reanalysis and
modeling of recent and possible future climates in the polar regions are
welcome.

This session is organized by Ralf Doscher and Ursula Schauer.
