The International Conference on Mathematical Geophysics meets every two years and is sponsored by the Committee on Mathematical Geophysics of the International Union of Geodesy and Geophysics. The Committee invites scientists working in any quantitative area of the dynamic Earth Sciences to submit abstracts of less than one page prior to 27th March 1998. U.S. participants requiring financial support should contact Daniel Rothman; European scientists should contact Didier Sornette.





CONFERENCE PROGRAMME

The Conference Programme is now available on the web.





INFORMATION FOR DELEGATES

Information for Delegates is now available. This page provides details of registration and how to reach Cambridge by air, rail or road.





REGISTRATION AND ABSTRACT SUBMISSION

The registration fee will be 175 and the accompanying persons fee 50. A programme for accompanying persons will be arranged once numbers are known.

We invite registration and abstract submission on the internet with payment by post. The registration and abstract submission forms are now available for electronic submission. Because of the large numbers of people wishing to submit abstracts for this meeting, the deadline for submission has been extended by one week Abstracts should now be submitted by 27th March 1998.




AIMS AND TOPICS

The aim of the forthcoming CMG98 is to concentrate on the fundamental processes that control the evolution of the Earth. To that end the title of the conference has been chosen to be The Dynamic Earth. The aim of the meeting will be to present fundamental results of relevance in the various areas of the Earth to a broad selection of the most active researchers in the quantitative Earth Sciences. There will be eight sessions of presentations under six main topics, which are:

1) Magnetic field generation and core dynamics

2) Mantle processes

3) Coupled ocean-atmosphere dynamics

4) Crustal processes: deformation, friction and rupture

5) Inverse theory

6) Modern numerical investigations

Each session will commence with a broad review presentation aimed at explaining the latest results and their foundations to specialists in the different areas of the Earth Sciences. These reviews will be followed by shorter talks expanding further on the most recent scientific investigations. A prominent feature of the meeting in the new, spacious Isaac Newton Institute will be a number of posters sessions, which will be arranged to be at convenient times so that all present can see and take part in discussions of the posters.

Contributions are invited to a variety of topics including:

1) MAGNETIC FIELD GENERATION AND CORE DYNAMICS

super-rotation of the inner core; core-mantle coupling; solidification of the inner core; dynamo models; secular variations; boundary conditions for the outer core; precession.

2) LARGE SCALE MANTLE CONVECTION

numerical models; dynamic topography; three-dimensional stirring; one versus two layer convection; geochemical consequences; convection in Earth and Venus; time-dependent convection and plumes; lower mantle tomography; planetary thermal history; convection as a dynamical system.

3) SMALL SCALE PROCESSES IN THE MANTLE

two phase flow; flow of fluids and magma through rocks; compaction; isotopic signatures; flow focusing; melt extraction.

4) ATMOSPHERIC DYNAMICS AND SECULAR VARIATIONS

transport, stirring and mixing; nonlinear interaction with small scale processes; gravity wave breaking; cloud formation; large scale dynamics; severe storms and weather; oceanic influences on climate; tropospheric and surface coupling; ensemble prediction systems; balanced motions; anthropogenic influences.

5) OCEAN CIRCULATION, GLOBAL CLIMATE, HEAT TRANSFER AND TURBULENCE

global oceanic processes; transport, stirring and mixing; satellite observations; atmospheric coupling; large scale turbulent motions; seasonal to decadal variability.

6) CRUSTAL PROCESSES: DEFORMATION, FRICTION AND RUPTURE

spatio-temporal seismicity patterns; distributed and localized deformation; earthquake slip histories; geodetic data and models; fractals; scaling laws; statistical physics of earthquakes; fracture mechanics; friction laws; damage rheology; mechanics of granular media; earthquake source mechanisms; rupture in heterogeneous fault zones; imaging of structures; fault zone head and trapped waves; rupture nucleation; dilatancy; fluids in faults; geo-electric signals; triggering and migration of earthquakes; precursors; prediction algorithms and signals; quantitative geomorphology; hydrodynamics of granular flows; erosion.

7) GEOPHYSICAL INVERSE THEORY AND IMAGE RECONSTRUCTION

nonlinear inverse theory; simulated annealing; genetic algorithms;probabilistic inverse theory; resolution of inverse problems; linearized problems; evolutionary algorithms; parallelisation; Monte Carlo; importance sampling; uniqueness; local optimisation; industrial geophysics.

8) MODERN NUMERICAL INVESTIGATIONS

finite differences, finite elements and finite volume methods; pseudo-spectral methods; computational geometry; grid generation; 3-D methods; hybrid techniques; large-scale modelling; parallel algorithms; irregular grids; boundary problems; irregular boundaries; modelling on a planetary scale; verification and accuracy of 3-D algorithms; performance scaling; domains of applicability; spectral elements.





CONFERENCE ARRANGEMENTS

We expect that participants will arrive some time on Sunday 12 July and there will be a Welcome Party that evening.
Lectures will run from Monday to Friday lunch time.

Most participants will probably wish to stay in New Hall College where we have reserved modern en-suite accommodation at 50 per person (single room) for dinner, bed and breakfast. We have also reserved some double accommodation in hotels.

We plan a series of social events for evenings and Wednesday afternoon.
We will have the Conference Dinner on Thursday evening in King's College at 35 a head (including wines).
