Monthly and Annual Means of the 1st Principal Component of the position of the North Wall of the Gulf Stream 1966-2000. NOTE: Month to month variability in the data is high because of Gulf Stream meandering. It is therefore advisable to use either annual mean values or averages over several months.When using this data please cite:
Taylor, A.H. and J.A. Stephens, 1980. Latitudinal displacements of the Gulf Stream (1966 to1977) and their relation to changes in temperature and zooplankton abundance in the NE Atlantic. Oceanologica Acta, 3(2), 145-149.
