  1. OCEAN-ATMOSPHERE-ICE (OAII) INTERACTIONS REPORT ARCSS ALL HANDS MEETING SEATTLE FEB. 2002 L.A. Codispoti and the OAII SSC http://arcss-oaii.hpl.umces.edu

  2. NEW: Carbon Cycling in Seasonally Ice-Covered Seas (Yager et al.)

  3. Investigations of the Western Arctic (a.k.a.) Western Arctic Moorings (T. Weingartner)

  4. Canadian Icebreaker Des Groseilliers and SHEBA Ice Camp

  5. Arctic Ocean Section (AOS)[Wheeler et al.]

  6. Proposed SBI Phase II Cruise Track

  7. OAII Modeling (Maslowski, et al.)

  8. OAII/SBI Paleoceanography

  9. Vorticity Index (mb) Years

  10. Holocene Pleistocene % Laptev Sea % N. Canada

  11. Rationale for SEARCH • The Arctic is in the midst of a major change - Atmosphere, Ocean, Land, Ecosystem, and Society. • The Arctic change is connected to changes in the atmospheric circulation of the Northern Hemisphere. • Observed impact on the ecosystem and society • Future course unknown, but • Fingerprint of global warming • Requires long-term program of observations, analysis, modeling, and assessment. • SEARCH science plan: http://psc.apl.washington.edu/search.

  12. Other Possible New Starts • Troposphere-Ice-Ocean Chemical Fluxes, Transformations, and Processes in Collaboration with SOLAS [Surface Ocean-Lower Atmosphere] • Nearshore Processes in Collaboration with LAII and RAISE • Model Inter-Comparisons

  15. BEST IDEAS X $0 = 0 Science WE HAVE A STRONG CASE, BUT WE ARE NOT MAKING IT STRONGLY ENOUGH TO THOSE WHO CONTROL THE PURSE STRINGS!! “Some months ago I wrote of the growing chorus of voices both in Alaska and at the national level favoring increased attention to Arctic research. The sound has not subsided, yet positive forward action on an idea of very real importance both to the nation and to Alaska remains elusive.” William R. Wood, Daily News-Miner, 1981 (in Norton, 2001)
