An intersection model for estimating sea otter mortality along the Kenai Peninsula

January 1, 1994

We developed an intersection model to integrate parameters estimated from three distinct data sets that resulted from the Exxon Valdez oil spill: (1) the distribution,
amount, and movements of spilled oil; (2) the distribution and abundance of sea otters along the Kenai Peninsula; and (3) the estimates of site-specific sea otter
mortality relative to oil exposure from otters captured for rehabilitation and from collected carcasses. In this chapter, we describe the data sets and provide examples
of how they can be used in the model to generate acute loss estimates. We also examine the assumptions required for the model and provide suggestions for
improving and applying the model.
