9. 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.

14. 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.
