Research Abstract

Formation and propagation of Alaskan Stream eddies and their impact on the chlorophyll a (chl-a) distribution in the western and central subarctic North Pacific were investigated through analysis of satellite data. Formation and propagation were suggested to be affected by wind stress and bottom topography, respectively. Alaskan Stream eddies contributed significantly to the chl-a distribution in the deep-sea region of the subarctic North Pacific thorough chlorophyll/nutrient-rich water transport from the Aleutian Islands to the deep-sea region of the subarctic North Pacific.
