Research Abstract

Mesoscale eddies in the western and central subarctic North Pacific were studied through analyses of satellite altimeter data and data from shipboard and Argo float observations. We found that the core water of a Kenai eddy formed in December 2006 south of the Kenai Peninsula was modified by surface cooling, cold water intrusions and eddy-eddy interaction. We also found that mesoscale eddies had a significant impact on zooplankton community.
