The waters north of Iceland are characterized by large hydrographic fluctuations. Warm and cold years are distinguished on the basis of the hydrography. Time-series data reveal that zooplankton biomass, capelin biomass, and capelin weight-at-age are all greater during warm years than during cold years. The chain of events that links hydrographic conditions with the observed ecological variations is discussed.
Keywords: capelin, environment, Icelandic waters, zooplankton
