North Pacific High Sea

The Bering Sea opens north of the Aleutian chain, where the Alaskan Stream sends Pacific water through the passages between volcanic islands. These channels feed currents along the northern side of the archipelago, linking open ocean and sea. Fog and powerful storms are familiar features of the region, especially in the colder months. Between the island shores and the distant Pribilofs, a vessel must cross a broad stretch of exposed water.
