The Bering-Aleutian Salmon International Survey (BASIS)

What is BASIS?

The Bering-Aleutian Salmon International Survey (BASIS) is NPAFC's coordinated program of cooperative research on Pacific salmon in the Bering Sea that was designed to clarify the mechanisms of biological response by salmon to the conditions caused by climate changes.

Scientific issues that provide necessary direction to the research include (but are not limited to):

• Seasonal-specific migration patterns of salmon and their relation to the Bering Sea ecosystem
• Key biological, climatic, and oceanographic factors affecting long-term changes in Bering Sea food production and salmon growth rates
• Similarities in production trends between salmon populations in the Bering Sea and common factors associated with their trends in survival
• Overall limit or carrying capacity of the Bering Sea ecosystem to produce salmon.
