This study combines a broad collection of fishery landing and survey data with data on Alaska Stellar Sea Lion and the physical environment tailored to the question of climate impacts on Alaska Stellar Sea Lion ecosystems. The analyses focus on the 1965-2002 period, a timeframe that spans a period of rapid declines in the western stock (western Gulf of Alaska, Aleutians, and Bering Sea) of Stellar Sea Lions. To date, it is not understood to what extent climate and natural ecosystem changes have influenced the declines in the western stock populations.
- Identify the space-time patterns of covariability between environmental and ecosystem indicators in the North Pacific, Gulf of Alaska, and Bering Sea
- Identify potential predictors for Alaska Stellar Sea Lion population changes
