Abstract

The record of atmospheric dust deposition as recorded by a deep sea sediment trap in the Sargasso Sea is presented. The record is shown to be consistent with the limited available data on directly measured atmospheric dust loadings. The seasonality of the sediment trap dust fluxis different from that of the atmospheric deposition as a result of seasonal biological cycles in the surface water. On the longer term thesediment trap dust flux undergoes quite large variations in the annual average flux from 3.6 to 9.4 mg m(-2) d(-1). These variations are shown to reflect changes in atmospheric transport efficiency from sourceregions in North Africa rather than changes in the strength of the dust source in that region. The changes in the dust inputs to this area of the Sargasso Sea appear not to have changed the flux of carbon reaching the deep water, and the implications of this are discussed.
