Talk 1:Tracing present and past ocean circulation and continental weathering with radiogenic isotopes
IFM-GEOMAR
Leibniz Institute of Marine Sciences at the University of Kiel
Talk Abstract
The budget and isotopic distribution of dissolved elements in seawater has been controlled by the style and intensity of continental weathering and for some elements also by ocean circulation. The radiogenic isotope composition of dissolved trace metals in the ocean represents a set of powerful tracers with a large potential for oceanographic and paleoceanographic research on time scales from the present back to the more distant geological past. I will provide an oversight on the present day processes controlling their distributions, which is also a subject of the GEOTRACES programme and will discuss some examples for applications to reconstruct the past marine environment.
