Abstract: | Zooplankton collections from the subarctic Pacific were analyzed from two periods (1956–1962 and 1980–1989). In this report, we document: 1) a positive correlation between the intensity of winter winds and subsequent summer zooplankton biomass in the subarctic gyre within these periods; and 2) a doubling of zooplankton biomass and a similar increase in pelagic fish and squid abundance between these two periods of time. Some possible explanations for these changes are considered. |
