Excerpt from North Pacific Oceanography, February April 1962 Good evidence was obtained of a significant westward velocity and transport in the Alaskan Stream southward of the Aleutian Islands and Alaska Peninsula as far westward as long. 175 Degrees W. Upwelling through the halocline was not evidenced south of the Aleutian Islands at long. 175 Degrees W., but it is suggested that, in years when the flow of the Alaskan Stream is not so pronounced, such a condition could occur. It does not appear that the temperature minimum stratum south of the Alaskan Stream at 150 to 200 meters could have been formed locally, and, therefore, the stratum must be the result of advection from the western Subarctic. The positions of the subsurface temperature front at lat. 46 Degrees N. And the surface salinity front at lat. 42 Degrees N. In the central North pacific revealed by analysis of summer data remained the same. This indicates that no seasonal shift of water masses occurs northward of the Subtropic boundary, and the dominant changes in the surface layer are the result of differen tial latitudinal heating and cooling rather than advection.
