Gulf Apex Predator-Prey Project

The goal of the Gulf Apex Predator-Prey Project (GAP) is to better understand predator-prey interactions in the western Gulf of Alaska as they relate to the decline of the western stock of Steller sea lions.

This website was created for laypeople and scientists alike. We invite you to explore the site to learn about the wide variety of GAP projects and how they have evolved since GAP began in 1999. Here you will find detailed information on the integrated components of GAP, including the suite of species and methodologies that have been used to explore the Kodiak marine ecosystem.
