Study on pelagic ecosystem response to climate variability in the　transition zone of central North Pacific Ocean using satellite derived　ocean surface current data

North Pacific Ocean, climate shift, marine ecosystem, sea surface height, EOF analysis

Satellite-derived time series ocean surface current data were analyzed to assess the influence of ocean surface current and climate change on the pelagic ecosystem of the central North Pacific Transition Zone. The influence of the low primary production regime was noticed in the ecosystem during the most significant climate change event of 1999-2002 characterized by the northward shift of the phytoplankton front. Thus, it is important to understand the influence of ocean surface current variability and climate change on primary productivity.
