This book investigates the precipitous decline of the Steller sea lion population in Alaskan waters, a phenomenon that has puzzled scientists and conservationists for decades. The National Research Council (US) convened a committee of experts to analyze the available data and identify the primary contributing factors. Their analysis considers a range of potential causes, including environmental changes, fisheries interactions, and disease, to present a comprehensive overview of the situation.

This comprehensive report is regarded as a critical scientific assessment of the Steller sea lion's population crisis. The authority perspective suggests it provides a detailed, evidence-based analysis for researchers, policymakers, and conservation organizations. The scope of the work indicates it is intended for a scientifically literate audience seeking an in-depth understanding of the complex factors affecting this marine mammal.
