Distribution and behavior of the lithogenic tracers aluminium and titanium in the upper water column of the Atlantic Ocean
Year: 2012
Type: dissertation
Abstract: The present thesis investigates the potential suitability of surface water dissolved titanium (Ti) concentrations as complementary dust tracer to dissolved aluminium (Al). Both metals reflect variations in the dust deposition into the surface ocean over different time scales, with seasonal timescales for Al and longer temporal scales for Ti. In order to lay the basis for future estimations of dust deposition from surface water concentrations of both metals, the behavior of Al and Ti is examined in the upper water column of the Atlantic Ocean. Detailed insights are given into the size distribution, removal processes and residence times of Al and Ti, in regions that largely differ in atmospheric inputs and biological productivity.
