Abstract:

A hydrocast survey was conducted near the western Aleutian Islands and in the Bering Sea in September 1992. Presence of the Alaskan Stream was indicated by temperatures > 4°C to depths in excess of 200 m. Geopotential topography showed the Alaskan Stream flowing through Near Strait into the Bering Sea, with branches also flowing northward through Amchitka and Buldir passes. Satellite-tracked drifter paths were in general agreement with these features. Transport through Near Strait was ≈5 × 106 m3 s−1. Previous research indicated that the Stream had been absent from the Strait for more than a year. Data from three current moorings (13-mo duration), however, suggested that the Alaskan Stream started flowing through Near Strait in October 1991 and continued into September 1992. This inflow had periods of both steady and variable flow.

More about this publication?
  • The Journal of Marine Research publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. In the area of biology, studies involving coupling between ecological and physical processes are preferred over those that report systematics. Authors benefit from thorough reviews of their manuscripts, where an attempt is made to maximize clarity. The time between submission and publication is kept to a minimum; there is no page charge.
