Pacific Arctic Group - overview
• PAG represents a forum for collaboration
and coordination with a focus on fostering
information transfer and field planning
• Partnership to plan, coordinate, and
collaborate on science activities of mutual
interest as appropriate
PAG Workshop – Shanghai, China
October 11-13, 2006
• Current PAG “membership” is led by an
interim Executive Committee consisting of
a Chair, Vice Chair, Coordinator, and a
chair of the Scientific Steering Committee
Scientific Steering Committee
• The PAG SSC is to include equal
representation by countries, including a
disciplinary mix. PAG SSC membership is
3 years, renewable for an additional 3
years (outlined in TOR).
• PAG SSC may form project groups to
address specific issues linked to the PAG
objectives
Pacific Arctic Region – Science Themes
Theme 1: Undertake seasonal and interannual ocean observations in the Pacific
Arctic Sector where recent maximum sea ice retreat is occurring.
Theme 2: Understanding oceanic and atmospheric processes in the Pacific Arctic,
including the feedback loops, are critical to mid-and low-latitude climate
variability.
Theme 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.
Theme 4: Identify and monitor ecosystem and biological indicators and
chemical tracers (e.g., ice, water column, benthic, higher trophic
organisms, isotopes and trace gases) of climate change in the Pacific
Arctic.
Theme 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.
Theme 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.
Theme 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 variability 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.
Theme 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, and the carbon cycle.
Theme 9: Nearshore coastal processes and subsea permafrost dynamics are
important processes in the shallow Pacific shelf areas are subject to climate
change impacts.
Theme 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.
PAG Secretariat
• Polar Research Institute of China (PRIC)
Shanghai, China
• provide administrative support for the functioning
of the PAG;
• provide maintenance to the PAG website;
• organize PAG meetings and record decisions
• communications function for the PAG Executive
Committee, providing a central point for
communications to and from the PAG.
PAG History
• Founded by IASC – PAG
held its first meeting at
Arctic Science Summit
Week in Kiruna, Sweden
in April 2003 – endorsed
by AOSB
• 5th annual meeting at
ASSW Hanover, USA
• 6 “core” member
countries – open meeting
with participation from
most ASSW attending
nations
PAG ASSW HANOVER
• Restructuring of IASC – implications for
PAG
– General support for change
– PAG to provide input to process, linked to
IASC
• Current focus on marine issues
– Discussion about association with AOSB
– Link with other marine organizations
PAG Korea meeting (18-22 April, 2007)
18 April Arrival at Incheon Airport
19 April Korean IPY launch event
Location: Event hall of The National Assembly in Seoul

PAG Activities 2007 - proposed
PAG Chief Scientist Coordination Meeting
PAG Model Coordination Meeting (to be developed)
Purpose:
1. Bring together Chief Scientists and possibly group leaders to share information on field
activities planned during ship-based operations in 2008, 2009 in the PAG area of interest.
2. Prepare description of planned cruise operations, including a combined station list, with
description of measurements to be made at each station and types of samples to be collected
for later analysis.
3. Identify sites and measurements in common and begin agreement on “standard sites” and
“core measurements” that are collected on all cruises
4. Look for opportunities for collaboration during or after cruises.
5. Look for opportunities for data integration and synthesis after cruises.
Venue:
• Fall 2007 (October/November) – location under discussion. Ottawa, Canada proposed
• Lead: Dr. Jackie Grebmeier – University of Tennessee; Dr. Chen Bo – Polar Research
Institute of China
