Poleward and equatorward currents in the Pacific Eastern Boundary Current in summer 1995 and 1998 and their relationship to the distribution of euphausiids

Differences in the north-south euphausiid distribution were observed between 1995 and 1998. In 1995, there was a much higher abundance of euphausiids in the region immediately north of Cape Blanco, while in 1998, euphausiid abundance was high throughout the survey area. We hypothesize this difference to be in part a result of differences in current patterns between the 2 years and the manner in which currents interact with euphausiid diel migration.
