  1. MARINE ECOSYSTEMSSub-Arctic & Arctic Sue E. Moore, NOAA/AFSC SEARCH SSC MEETING 28 October 2008

  2. Sub-Arctic Marine Ecosystems • BEST/BSIERP: Understanding the Bering Sea (shelf) Ecosystem • $52M study; 2007-2012 • BEST/NSF: PO – euphausiids (OCH Ho.) • BSIERP/NPRB: euphausiids/fish – mm/LTK • Scope & Study Area – refer to booklet: note LTK, modeling & data mgt. are high profile • BEST/BSIERP: component of ESSAS

  3. Sea Ice: sub-Arctic & Arctic ‘channeling’ Jim Overland….. • Sea ice signal ‘decoupling’ between sub-arctic and Arctic systems • 2007 extreme sea ice retreat followed by 2008 extreme extent in Bering Sea • What is the response of each system? • Will the ‘ice seal’ ESA listing decision follow 2008 polar bear decision?

  4. Arctic Marine Mammals and Climate Change • Special Volume of Ecological Applications, March 2008 • Broad undertaking, including papers by: Walsh – Arctic CC overview Bluhm & Gradinger – Ecosystem Change conceptual models Murray – Archeological overview *Ragen et al. – Human/management overview

  5. RELATIONSHIP TO SEA ICEMoore and Huntington: Ecological Applications

  6. Available Data & Partnerships e.g., DOI/ MMS Surveys: 27 YEAR DATABASE NOTE: relevanceof NSF: SBI & SNACS data

  7. BELUGA TRACKSNOAA/ABWC: Collaboration with Subsistence Hunters

  8. Arctic Observatories: AUTONOMOUS RECORDERS *Note: NOAA S&T funding for 3-phone IPY deployment

  9. Detect Gray Whale Calls in Beaufort Seathroughout winter `04 [until May: Stafford et al. Arctic]
