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 will be held at the Hotel Mercure in Châteauneuf-le-Rouge at the foothill of the Sainte Victoire Mountain.

The organiser will book hotel rooms for funded participants during the workshop.


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.

Working groups

All participants will choose 1 or 2 working groups:

Biological productivity
Oceanic circulation
Particle flux and sedimentation rate
Physical and/or biogeochemical modeling.

Travel support

Financial travel support will be available for about 60 participants in the form of subsidies for airfare and ground transportation (capped depending on travel origin). Hotel rooms and meals will be provided by the organizers: 2 nights for participants from Europe and 3 nights for participants from overseas (4 nights for US participants). Those who can cover their own travel expenses are encouraged to do so.

The planning committee will select participants to receive travel support based on a review of pre-registration information received by the deadline of 1 June 2018. The anticipated contribution to the workshop goals will be used as the basis for selection among the applicants.

Decisions will be communicated to participants in July. Selected participants will then be invited to finalize their registration for the workshop. The organizers will take care of the hotel booking for funded participants for the duration of the workshop.


The deadline for pre-registration is 1 June 2018.

You must pre-register for the workshop, as all participants will be chosen from those who have pre-registered. It is not possible to register to attend after the 1 June deadline.
