Papers are invited for Session 157: "Arctic Sea Ice Variability
Interacted with Atmospheric and Ocean Circulation Patterns" being
convened at the 2008 Ocean Sciences Meeting on 2-7 March 2008 in
Orlando, Florida. The meeting is co-sponsored by the American Society of
Limnology and Oceanography, American Geophysical Union, The Oceanography
Society, and Estuarine Research Federation.
Session Description:
Cryosphere is an important component of the global climate system
consisting of five subsystems: atmosphere, hydrosphere (hydrology and
ocean), cryosphere, biosphere, and lithosphere. Particularly in the
Arctic Ocean, fate of sea ice not only indicates climate change, but
also has direct relation with and feeds back to atmosphere, ocean, and
other subsystems. Therefore, future fate of sea ice, such as summer ice
free conditions as many IPCC models project at the end of 21st century,
may alter the entire picture of present climate in the atmosphere,
ocean, and other components. Inspired by the ongoing research activities
of the International Polar Year during 2007-2009, this session invites
papers focusing on fate of sea ice in the following scientific driving
questions (but not limited to): 1) Similar to global/arctic warming,
what percentage of the arctic sea ice cap melting, particularly the
multi-year (aged) sea ice, is attributed to natural variability and
anthropogenic activity caused by the oceanic (Atlantic Water and Pacific
Water) and atmospheric warming? 2) What are the differences and
similarities between the 1930s and 1990s warming in terms of sea ice
melting? Are there any similar phenomena in the 21st century? 3) How can
the sea ice-tidal dynamics be implemented to a global model to better
represent sea ice deformation and interaction with upper ocean dynamics?
4) What percentage of the arctic amplification is attributed to sea
ice/ocean albedo feedback, cloud radiation feedback, and the lower
latitude atmospheric circulation anomaly? How do the mechanisms compete
in the high Arctic? 5) How do we identify the thermodynamic and dynamic
effects on arctic sea ice in terms of depletion and advection of sea ice
due to Arctic Oscillation (AO)/North Atlantic Oscillation (NAO) and
Dipole Anomaly (DA)? 6) How do intensified arctic atmospheric cyclones
accelerate melting of the arctic sea ice during positive phase of AO/NAO
and DA? Can the weakened cyclones help produce sea ice during the
negative phase of AO/NAO and DA? 7) What percentage does sea ice anomaly
contribute to freshwater anomaly in the pan-Arctic? Similarly, how
important is the residence time of freshwater anomaly in producing new
ice although aged ice has been decayed?
