  1. IPY: Collaborative Research on the State of the Arctic Sea Ice Cover: An Integrated Seasonal Ice Zone Observing Network (SIZONET) • Investigators: Eicken, Johnson, Lovecraft, Heinrichs, Gradinger (UAF), Perovich, Sturm (CRREL) • Contributing partners: Nghiem (JPL), Markus (GSFC), Krupnik (Smithsonian), Shirasawa, Tateyama & Enomoto (Japan), Haas (Germany), Barber & Melling (Canada), Gerland (Norway) • Further linkages through CliC Sea-Ice Working Group (proposed), Sea-Ice Knowledge and Use (SIKU) IPY Project, UA North by 2020 IPY Forum • Outreach partnerships with Bering Sea School District, UA North by 2020 IPY Forum; Int’l Field Course, Barrow, May 2008 • Principal contacts: Hajo Eicken (hajo.eicken@gi.alaska.edu), Don Perovich (donald.k.perovich@erdc.usace.army.mil)

  2. Scope & aims • SIZ expanding, lack of data (thickness, mass balance, albedo) to assess whether moving to new state (SEARCH) • Ice deformation & and role of snow • Okhotsk Sea as harbinger of Arctic change? • Does local change at scale relevant to stakeholders conform with pan-Arctic change?

  3. Approach • Sea-ice system services & windows of opportunity • State vs. Stake: Institutional analysis and local calibration • Integration of seasonal ice into modeling and remote-sensing

  4. Variables to be measured • Remote sensing (pass/act MW, vis/IR) • Shore-based (radar, mass-balance sites) • Drifting buoys/mass-balance sites • Aerial surveys • On-ice measurements • Primary sites: Wales (BStr), Barrow, Alert • Partner sites: Okhotsk Sea, Svalbard, eastern Beaufort, Tiksi • Aerial surveys: April/May ‘07-’10 • On-ice measurements: January, April, June ‘07-’10

  5. Data management, archival, distribution • AK Ocean Observing System, aoos.org • Geographic Information Network of AK, gina.alaska.edu • Metadata (FGDC/ISO) from templates to NSDI/GOS • Near-realtime: Buoy/mass-balance (annual certification), radar/web cam, satellite data • Campaign data (available within 1-3 months): thickness flights, ice-core data

  6. Data management, archival, distribution • Central Arctic Observing System data portal?

  7. Linkages & coordination • Bering Strait Observatory • North Pole Environmental Observatory • Beaufort Gyre Observatory (thickness flights & buoys) • Socio-economic state project • ELOKA: local observations and indigenous knowledge; discuss potentialstandardization ofprotocol HyperResearch 2.7 sample screen: Standardization of keywords (“codes”)?
