IPY Collaborative Research on the State of the
Arctic Sea Ice Cover An Integrated Seasonal Ice
Zone Observing Network (SIZONet)

• Contributing partners Nghiem (JPL), Markus
  (GSFC), Krupnik (Smithsonian), Shirasawa,
  Tateyama Enomoto (Japan), Hendricks (Germany),
  Haas Barber (Canada), Gerland (Norway)
• Linkages and integration through CliC Sea-Ice
  Working Group, Sea-Ice Knowledge and Use (SIKU)
  IPY Project, UA North by 2020 IPY Forum
• Outreach activities with Bering Sea School
  District, UA North by 2020 IPY Forum Intl Field
  Course, Barrow, May 2008

Aims

• SIZ expanding, lack of data (thickness, mass
  balance, albedo) to assess whether moving to new
  state
• Ice deformation snow (Okhotsk Sea as analog of
  future Arctic SIZ?)
• Does local change at scale relevant to
  stakeholders conform with pan-Arctic change?

Observations Coastal mass budget optics
measurements (w/ feedback from stakeholders)
Coastal ice observations by Iñupiaq ( Hokkaido)
ice experts - database Drifting buoys
Thickness and property surveys (Alert, Barrow,
Bering Okhotsk Sea)
3

• Sea-ice system services (SISS) as an aid to
  integration of pure and applied science
• Climate regulator, marine hazard, coastal buffer
• Coastal platform roadway
• Cultural services from icescape
• Support of foodwebs and biological diversity
• State vs. Stake Institutional analysis
  prioritization
• Calibration through work with local experts and
  stakeholders

Coastal ice Integrating RS local obsns

• Wales
• 11/7/07 - 1st pancake ice
• 11/11/07 - coastal slush berm washed away, one
  boat w/ hunters got 18 seals
• Shishmaref 11/15/07 - slush ice berms protect
  shoreline
• 12/14-25 - shorefast ice repeatedly forms
  breaks out
• 12/26 ice blown in forms persistent shorefast
  ice belt
• Barrow
• 11/3/07 - 1st local ice formation on Chukchi Sea
  side
• Early Nov - 12/25/07 Unstable shorefast ice w/
  break-outs
• 12/26/07 Shorefast ice has stabilized

Integration

• AON local observations snow ice thickness
  properties buoys remote sensing ground-based
  obs.
• International CliC Arctic Sea Ice Working Group
  (WS Fall/Winter 2008) - Coordination of
  observations, development of joint protocols and
  associated tools Sea-ice knowledge use (SIKU)
  IPY project
• Across stakeholder groups Local government
  communities (NSB sea ice workshops) exchange
  with industry (JIP?) SIKU project
• Pure applied science North by 2020 -
  Coastal Offshore Oil Gas theme synthesis
  workshop (Reducing environmental risk through
  information management exchange) -

• International Barrow Sea Ice Field course (May
  2008) Concepts practical approaches to
  integrated observing programs
