[Aqualist] EGU session on past changes in the Atlantic Meridional Overturning Circulation

[Laurie Menviel]

Dear Colleagues,

We would like to draw your attention to our session CL1.20/OS1.6: “Past changes in Atlantic Meridional Overturning Circulation (AMOC) structure, variability, and their impact on climate and biogeochemistry” at the upcoming EGU (European Geosciences Union) conference in Vienna 8-13th April 2018.

Full description of the sessions can be found at the end of this e-mail and also here:
http://meetingorganizer.copernicus.org/EGU2018/session/27934

The session will have two invited talks given by Jerry McManus and Bette Otto-Bliesner. We look forward to many excellent contributions. Please feel free to distribute this to interested colleagues and mailing lists.

Note the submission deadline: 10 January 2018, 13:00 CET.

Thank you,

Jerry Tjiputra, Jörg Lippold, Laurie Menviel, and Pepijn Bakker (conveners)


Session description:
The AMOC influences surface temperature and precipitation patterns around the globe by regulating the transport of heat, freshwater and carbon. The AMOC – e.g. its overall strength, the contributions of different water masses and the locations where deep waters are formed and ventilated - have varied significantly in the past, impacting not only North Atlantic climate but also other regions through both atmospheric and oceanic teleconnections. The mechanisms leading to these changes in AMOC are still poorly constrained. Our ability to predict anthropogenic climate change, therefore, depends critically on our understanding of AMOC structure, variability and sensitivity to past climate changes. This session aims to bring together paleoproxy records (e.g., d13C, 231Pa/230Th, and εNd, among others), modelling studies, as well as novel methodologies that combine both approaches, to characterize the spatial structure and temporal variability of the AMOC on all timescales and advance our understanding of its impact on climate and biogeochemistry.
