The influence of coastal origin eddies on oceanic plankton distributions in the eastern Gulf of Alaska

Author(s): Batten SD and Crawford WR

Abstract

Mesoscale anticyclonic eddies that form along the eastern continental margin of the Gulf of Alaska in winter transport large quantities of coastal water to the open ocean. The Continuous Plankton Recorder (CPR) sampled repeated transects that passed close to, or through these eddies in 2000 and 2001. Shelf species of diatoms and calanoid copepods were recorded in CPR samples within, or in close proximity to eddies and they persisted through the sampling period. Several oceanic taxa also showed higher concentrations within the eddies. Significantly reduced occurrences of shelf taxa in oceanic samples were seen in 2001, coinciding with a weaker eddy than observed in 2000.
