Strategic Goal #1: Protect, restore, and manage coastal and ocean resources through an ecosystem approach to management. Strategic Goal #2: Understand climate variability and change to enhance society’s ability to plan and respond. Ecosystem Goal Team Climate Goal Team NOS NWS OAR NMFS NESDIS NOAA Matrix Science

FY05 Plans: Observe Preserve and expand NPCREP’s biophysical observing system to detect climate impacts. –Deploy and recover middle shelf moorings. –Initiate a spring biophysical survey of the Bering Sea shelf. –Conduct a pilot summer plankton survey in the Bering Sea.
11
FY05 Plans: Understand Achieve a mechanistic understanding of climate- ecosystem interactions. –Study transport of larvae within the shelf. –Explore the role of eddies in cross-shelf flux. –Build a conceptual model for the eastern Bering Sea. –Undertake retrospective analyses of Gulf of Alaska larval fish.
12
FY05 Plans: Predict
13
FY05 Plans: Advise and Inform Provide essential information on climate and ecosystems to stakeholders. –Improve climate-ecosystem advice to the North Pacific Fishery Management Council. –Develop an NPCREP website. –Support the Bering Climate web site http://www.beringclimate.noaa.gov/. –Begin development of a Gulf of Alaska climate web site.

FY05 Effort and Spending
15
Challenges and Priorities Challenges: Secure funding support and ship time. Integrate new technology to achieve real-time reporting of in situ observations. Priorities: Establish observation network. Develop tools to synthesize/integrate large numbers of indices or metrics. Increase understanding of mechanisms. Incorporate environmental data into forecast/stock assessment models.
