Abstract

Millennial to submillennial marine oscillations that are linked with the North Atlantics Heinrich events and Dansgaard–Oeschger cycles have been reported recently from the Alboran Sea revealing a close oceanatmosphere coupling in the Mediterranean region We present a highresolution record of lithogenic fraction variability along IMAGES Core MD 952043 from the Alboran Sea that we use to infer fluctuations of fluvial and eolian inputs to the core site during periods of rapid climate change between 28000 and 48000 cal yr BP Comparison with geochemical and pollen records from the same core enables endmember compositions to be determined and to document fluctuations of fluvial and eolian inputs on millennial and faster timescales Our data document increases in northward Saharan dust transports during periods of strengthened atmospheric circulation in high northern latitudes From this we derive two atmospheric scenarios which are linked with the intensity of meridional atmospheric pressure gradients in the North Atlantic region
