Latitudinal displacements of the gulf-stream (1966 to 1977) and their relation to changes in temperature and zooplankton abundance in the ne atlantic

Abstract

lt is shown that the north wall of the Gulf Stream was displaced southward during 1966 to 1971 and returned north ward after 1973. While there was no clear relation with any of severa! relevant wind and .. PtS:.~~ ure i?dices, there were similar trends in sea-surface temperature, salinity and abundance-ofzooplankton in the NE Atlantic. The displacements of the Gulf Stream are therefore part of a large-scale change encompassing most of the North Atlantic. These changes are either separate manifestations of variations in the global atmospheric circulation, or the changes in the NE Atlantic are the indirect result of variations in the Gulf Stream.
