Climate and Chlorophyll a: Long-Term Trends in the Central North Pacific Ocean

E L Venrick et al. Science. .

Abstract

Since 1968 a significant increase in total chlorophyll a in the water column during the summer in the central North Pacific Ocean has been observed. A concomitant increase in winter winds and a decrease in sea surface temperature suggest that long-period fluctuations in atmospheric characteristics have changed the carrying capacity of the central Pacific epipelagic ecosystem.
