The Pacific Arctic Group
Meeting Opened inShanghai on October
11-13th
To improve
the cooperation and collaboration among the member countries in Pacific Arctic
regions during the International Polar Year, the Pacific Arctic Group meeting
opened on October 11-13th, 2006 in Shanghai.
Around 30 officials and scientists from
Canada, USA,
Russia, Japan,
Korea and China gathered
together to discuss the cooperation fields, ship coordination and other issues
of the member countries for IPY. This meeting turned out to be very
productive , and ten themes was
made at this meeting: (1) undertake seasonal and interannual ocean observations
in the Pacific Arctic Sector where recent maximum sea ice retreat is occurring.;
(2) understanding oceanic and atmospheric processes in the Pacific Arctic,
including the feedback loops, are critical to mid-latitude climate variability;
(3) monitoring fresh water input via precipitation, riverine input, oceanic
input, glacial and sea ice melt in the Pacific Arctic sector will improve our
understanding of mid-latitude climate variability and provide additional
information to support theme 1; (4) identify and monitor ecosystem and
biological indicators (ice, water column, benthic, higher trophic organisms) of
climate change in the Pacific Arctic; (5)investigate sea ice thermodynamics
including sea ice thickness, extent, and its interactions with ocean and
atmospheric forcing in the Pacific Arctic region; investigate sea ice dynamics
such as sea ice drift, interactions between different ice packs; (6)
understanding the connectivity of warm Atlantic inflow to the Pacific sector,
heat flux throughout Arctic, and associated biodiversity/invasion of
Atlantic-species into the region. Physical gateways should be mapped and
monitored, including outflow through the Canadian Arctic Archipelago; (7) the
Arctic Ocean is very poorly mapped from the
seafloor to the ice above.
Significant information gaps include the bathymetry, biodiversity, and
knowledge of ocean currents and their variabililty over space and time. Exploration of the
unknown Pacific Arctic region is essential for the construction of base maps
necessary for the planning of future monitoring efforts; (8) the Pacific water
inflow through the Bering Strait region is a key conduit for heat, salt,
nutrients, and biological material (including genetic material) to the Arctic
basin that influences sea ice cover, halocline formation; (9) near shore coastal
processes and sub sea permafrost dynamics are important processes in the shallow
Pacific shelf areas are subject to climate change impacts; (10) the open and
closing of the Pacific gateway has occurred over geological time periods with
dramatic impact on the Arctic system. The paleorecord provides a long-term
record for comparative evaluation of climatic processes relative to contemporary
studies in prior themes.
The
Pacific Arctic Group (PAG) is a loose confederacy of institutes and individuals
having a Pacific perspective on Arctic science. Organized under the
International Arctic Science Committee, the PAG has the mission to serve as a
Pacific Arctic regional partnership to plan, coordinate, and collaborate on
science activities of mutual interest. PAG now has six member countries and
several observer countries, the PAG secretariat and website are located in Polar
Research Institute of China, Martin Bergmann is the Chair, Zhanhai Zhang is the
vice chair.
