Long Distance Movements and Disjunct Spatial Use of Harbor Seals (Phoca vitulina) in the Inland Waters of the Pacific Northwest

Abstract
Worldwide, adult harbor seals (Phoca vitulina) typically limit their movements and activity to 400 km. Disjunct spatial use patterns observed provide new insight into general harbor seal behavior. Long-distance movements and disjunct spatial use of adult harbor seals have not been reported for the study region and are rare worldwide in such a large proportion of tagged individuals. Thus, the ecological influence of individual seals may reach farther than previously assumed.
