03.12 - 05.12.2018  
Aix-Marseille, France

The joint GEOTRACES/PAGES workshop, titled "Trace element and isotope proxies in paleoceanography: A synthesis workshop" will be held from 3-5 December 2018 in Aix-Marseille, France.


The workshop on the synthesis of geochemical proxies used in paleoceanography aims to establish the strength, limits and conditions of application of a given proxy.

There is a vital need for a synthesis of geochemical proxies used in paleoceanography to improve interpretation of commonly used proxies. This synthesis is timely in view of the wealth of new data coming from GEOTRACES and contemporary programs.

The workshop will bring together expertise from GEOTRACES, PAGES and the broader oceanographic community of observationalists and modelers that will exploit new data to provide a more rigorous calibration of proxies and interpretation of their records.
