Commission on Earth Structure and Geodynamics

Commission Meeting at Hanoi, August 24, 2001

Meeting on Friday, 24/08/2001, 18:00

Attendance was so low that the meeting was moved to the restaurant of the Government Guest House. The small group discussed the two topics:

Joint Symposia at Sapporo
- The Earth’s core: structure, evolution and the generation of the magnetic field (with IAGA, IAVCEI, perhaps Geodesy)
- Mantle reservoirs constraints from geochemistry, seismology, mineral physics and geodynamics ( with IAVCEI).
- There was a feeling that an additional symposium (probably with IAVCEI) should address questions of the upper mantle and transition zone, such as subduction and deep earthquakes, deep continent ocean differences, generation of mantle melts, mapping of plumes in upper mantle, water in the transition zone etc- A good title has to be found.
- Barbara has suggested a symposium on "Continuously excited free oscillation" (with IAMAS). There were some doubt if there would be a critical mass of speakers.
There was a discussion on a possible task group on "Reference Earth Models". This could give some "official blessing" to the ongoing activities co-ordinated by Gabi Lashe ( who was present). Gabi thought that would be helpful and could attract people from outside the USA to participate. She would be the natural chairwoman for the task group.

Things I need to discuss with Barbara:

Exact title for joint symposia, keywords, possible convenors.
Members of the Commission on Earth Structure and Geodynamics to be appointed.
Members of the Task Group on Reference Earth Model ( in Coordination with Gabi, if she is going to be chairwoman)
