The 17th Symposium of SEDI, Study of the Earth's Deep Interior, a Committee of IUGG, will be held in Zurich, Switzerland, from 11th to 15th of July, 2022 (UTC+1).
The meeting took place at Earth Sciences building at ETH Zurich . The Institute of Geophysics, ETH Zurich and The Institute of Earth Sciences, Academia Sinica are co-organizing the SEDI 2022 in Zurich.
SEDI is an international scientific organization dedicated to the Study of the Earth's Deep Interior. The ultimate goal of SEDI is an enhanced understanding of the past evolution and current thermal, dynamical and chemical state of the Earth's deep interior and of the effect that the interior has on the structures and processes observed at the surface of the Earth. The 'deep interior' is generally considered to be the core and lower mantle, but interest may extend to the surface, for example, in the study of mantle plumes or dynamics of descending lithospheric slabs.

The scientific questions and problems of interest to SEDI cover all aspects of the evolution of the Earth's deep interior including composition, structure and dynamics of the inner and outer core, the geodynamo and the magnetic field secular variations, the core cooling, the core-mantle boundary region, the lower mantle structure, composition and dynamics as well as the nature and location of deep geochemical reservoirs.

Code of Conduct

SEDI symposiums are open and can be attended by anyone interested in the science related to the interior of the Earth and planets. SEDI is committed to providing a safe and welcoming environment for all meeting participants conducive to productive scientific exchanges. All participants of the meetings, including session chairs, speakers, poster presenters and all other attendants are expected to abide to the following guidelines which constitute the meeting's code of conduct:
  • Meeting participants are expected to communicate with one another in an open, considerate, mindful, respectful and collaborative manner- Diversity of views and opinions should focus on ideas rather than attacks on individuals or groups
  • Meeting participants are expected to follow the rules and policies of the meeting venue, accommodations, and field trip locations
  • Meeting participants are expected to be mindful of their surroundings
Reported unacceptable behavior by participants will lead to action by the SEDI meeting organisers and/or SEDI officers, which may include immediate removal from the meeting without warning or refund. Examples of unacceptable behavior include physical and verbal abuse of any form.
