  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), 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; 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) • Data access: CADIS web site; ak.aoos.org, www.gi.alaska.edu/BRWICE, www.sizonet.org (May 2008) AON/Arctic Integration Workshop

  2. 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) AON/Arctic Integration Workshop

  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 AON/Arctic Integration Workshop

  4. Coastal ice: Integrating RS & local obs’ns 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 Nov 17, 2007; SSM/I AON/Arctic Integration Workshop

  5. 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) - www.alaska.edu/ipy/north2020/oil.xml • International Barrow Sea Ice Field course (May 2008): Concepts & practical approaches to integrated observing programs AON/Arctic Integration Workshop
