Reconstruction of sea surface salinities in the eastern equatorial Pacific Ocean over the past 90,000 years detected strong millennial-scale fluctuations that are associated with the migration of the tropical Atlantic Intertropical Convergence Zone. Thus, millennial-scale fluctuations of moisture transport constitute an important feedback mechanism for abrupt climate changes, modulating the North Atlantic freshwater budget and hence North Atlantic ocean circulation.
