Abstract. Dall’s porpoise, Phocoenoides dalli (True), is commonly encountered over the continental shelf of North America and in offshore and pelagic waters of the western and eastern North Pacific Ocean.

In North American Arctic regions, herds of caribou (Rangifer tarandus) settle during the summer in the barrens—rather flat wasteland with little vegetation.

INTRODUCTION – SELECTED SPECIES AND STUDY AREA SPECIES SELECTION PROCESS The goal of this project is to describe th e habitat of fourteen highly migratory marine mammal and seabird species in the Eastern North Pacific and based on this habitat, to suggest locations for future marine protected areas.

Albacore Distribution. Albacore are widely distributed throughout the world's marine ecosystems in tropical, sub-tropical, and temperate zones of the Pacific, Atlantic, and Indian Oceans. In the Pacific Ocean, it is generally believed that there exists two stocks of albacore, one in the North Pacific hemisphere and one in the South Pacific hemisphere.

These marine mammals inhabit the nearshore coastal waters of the northeast Pacific Ocean and the marine waters in and adjacent to Alaska’s parklands. Changes in the distribution and seasonal migrations of these pinnipeds have been documented and linked to the availability of high-quality prey that varies both temporally and spatially (Womble.

The eastern North Pacific is a species-rich area with a total of 30 marine mammal species known to occur in Oregon and Washington waters. The seasonal abundance and distribution of marine mammals in Oregon’s near-shore waters is not well understood.
