1. Identifying Information Needs and Research Priorities for the North Aleutian Basin of Alaska Kirk LaGory North Aleutian Basin Information Status and Research Planning Meeting Minerals Management Service Anchorage, Alaska November 28—December 1, 2006

2. 2 Meeting Goal Recommend research to support an assessment of the potential environmental impacts of oil and gas development in the North Aleutian Basin program area on marine, coastal, and human resources

3. 3 Two proposed lease sales─2010 and 2012 Each requires an assessment of different phases of activities –EIS prior to sale –Post-lease EA on exploration activities –EIS of construction and operations Studies Will Be Used to Support Assessments Related to Proposed Lease Sales

4. 4 The North Aleutian Basin Contains Important Resources Ecologically important area –Fish and shellfish populations –Seabirds and waterfowl –Marine mammals, including the endangered northern right whale and Steller sea lion and threatened sea otter Coastal communities that depend on resources of the Basin Cultural resources Commercial fisheries Subsistence resources

5. 5 Coastal Communities

6. 6 Refuges, Parks, and Preserves

7. 7 Walrus Haul-out Areas

8. 8 Steller Sea Lion Rookeries and Haul-out Areas

9. 9 Meeting Overview Day 1: Presentations by researchers in relevant topical areas Day 2 and 3: Breakout sessions for five working groups –Physical oceanography, ecosystems, oil spill fate and effects –Socioeconomics, subsistence, local and traditional knowledge –Fish and commercial fisheries –Birds –Marine mammals Day 4: Presentation of working group results Working Groups are asked to develop specific study profiles MMS will prioritize and fund study projects in the area, beginning in FY07

10. 10 Elements of MMS Study Profiles Need for study and relevance to MMS mission Study objectives including hypotheses to be tested Methods Timing including start date and duration Cost and level of effort

11. 11 Several Types of Studies Can Be Considered Analyses of existing data sets Resource inventories Studies of trends in status and distribution Targeted research to address topical areas Model development Database development

12. 12 Impact Analysis Terminology  Oil and Gas Development  Activity Phase (e.g., exploration, construction, operations, decommissioning)  Activity (e.g., seismic surveys, drilling, trenching)  Impacting Factor (e.g., noise, disturbance of substrate, traffic, accidents)  Affected Resource (e.g., species, habitats, economy, subsistence use)  Affected Resource Attribute (e.g., species life stage, special use areas, jobs, hunting, recreational fishing)

13. 13 Impacting Factors Impacting factors are those aspects of an action that result in impact Examples: –Noise generated by seismic surveys –Habitat disturbance caused by trenching –Ship traffic during operations

14. 14 Resources Resources are biological, physical, cultural, and socioeconomic components of the Basin Examples: –Sea otter –Groundfish –Nearshore ecological communities –Demographic patterns –Subsistence –Jobs –Public services

15. 15 Resource Attributes Resource attributes are those characteristics of the resource that are of greatest concern or importance for sustainability Examples: –Migration pathways –Food resources –Breeding areas –Important life stages

16. 16 Simple Impact Model Oil and Gas Development Exploration Resources And Resource Attributes Affected Resources And Resource Attributes Affected Resources and Resource Attributes Affected Operation Resources and Resource Attributes Affected Decommissioning Resources and Resource Attributes Affected Seismic Surveys and Test Wells Spills Seismic Surveys and Test Wells Spills Construction Noise Vessel Traffic Spills Noise Vessel Traffic Spills Noise Explosives Vessel Traffic Noise Explosives Vessel Traffic Platform and Production Well Construction Pipeline Trenching Spills Platform and Production Well Construction Pipeline Trenching Spills

17. 17 Considerations for Identifying Information Needs and Recommended Studies Need to view North Aleutian Basin as a “system” of interdependent parts Focus on important parts (resources) of the system that are relevant to assessment of impacts –Which resources could be most affected by oil and gas development actions? –Which activities and impacting factors could have the most important effects? –What other factors could affect the resources of interest? Look for opportunities to identify representative species or groups for study

18. 18 We Will Focus on a Series of Questions to Arrive at Study Recommendations 1.What aspects of oil and gas development could affect resources in the Basin? 2.What are the important resources of concern in the Basin? 3.What are the important resource attributes for consideration? 4.What are the most important oil and gas impacts that affect resources of concern? 5.How well do we understand each resource in the Basin and the potential effects of oil and gas development?

19. 19 What makes a resource or resource attribute important? –Ecological value Importance to system Sustainability of resource or system Rarity –Economic value –Societal or cultural value What makes an impacting factor important? –Duration –Magnitude –Spatial extent of effect –Importance of the resource affected Prioritization
