2008 CIG Workshop on Mathematical and Computational Issues in the Solid Earth Geosciences

CIG Workshop on Mathematical and Computational Issues in the Solid Earth Geosciences

CIG sponsored a workshop on Sept. 15-17, 2008, in Santa Fe, NM, to bring together solid-earth geoscientists, mathematicians, and computational and computer scientists to focus on specific issues arising from a range of solid-Earth dynamics problems that have proven both difficult and critical for progress in studying and modeling the dynamics of the planet. These problems form the core activities for CIG and provide new challenges and opportunities in multiscale/multiphysics modeling and inference.

Workshop Goals

This workshop focused on three related “grand challenge problems” and their attendant mathematical/computational issues:

  1. Mantle Convection and Lithospheric Deformation (large scale solid deformation with complex rheologies)
  2. Magma Dynamics (multi-physics problems: Coupled fluid/solid flow in strongly deformable, reactive media)
  3. Crustal Dynamics and the Earthquake Cycle (Multiscale brittle mechanics and fault evolution)

The geophysical models at the heart of this workshop provided a common set of mathematical and computational problems that are essential for studying coupled natural systems. These include linear and nonlinear solvers and preconditioners for coupled problems, multi-scale methods for systems with space-time localization, multi-scale material modeling, and data-assimilation and inversion for integrating observations and dynamics.

These problems complement, but have significant differences from other application areas such as subsurface flow or climate modeling. Thus a primary goal of this workshop was to foster new collaborations between solid Earth scientists, mathematicians, computer scientists, and computational scientists that can make significant progress on these critical problems. The meeting format was two and a half days of talks and discussion that closely connected the Earth science applications and mathematical/computational problems and methods. In addition, the workshop discussed critical issues in developing, disseminating and supporting advanced, collaborative modeling software for the general community, which is central to the CIG mission.

Support and Expenses

Partial travel support will be available to attendees, which will be issued as a reimbursement after the meeting concludes. Air travel must be via a U.S.-based carrier in order to receive reimbursement.

Attendees must make and pay for their own travel arrangements. This includes reserving and paying for a hotel room. CIG has negotiated a discount for a certain number of hotel rooms (described below). However, the discount is only available on a first-come, first-served basis.



Santa Fe Hilton, 100 Sandoval Street, Santa Fe, New Mexico, 87501-2131, Tel: 1-505-988-2811, Fax: 1-505-986-6435.
Reservations must be received by August 23, 2008. After this date, reservations will be accepted on a space and rate availability basis only.

To register online:

  1. Go to Santa Fe Hilton website
  2. Click Reservations at the top left corner
  3. Use the form to request your dates, smoking preference, etc.
  4. Click "Need to Book Multiple Group Reservations?" and fill in code CIT to obtain special rate of $99 (plus tax) per night

If you have trouble using the online system (e.g., the wrong price comes up), call 800-336-3676. Again, the reservation is under the name California Institute of Technology or CIT. Rooms must be guaranteed at the time of reservation with a major credit card or first night's payment.

There will be a few rooms available on the 13th and the night of 17th, should you want to stay a bit later, but those nights are not eligible for reimbursement. Also, at this time the hotel is sold out for the 12th and 18th.

Cancellations must be made three days before midnight of the day of arrival in order to avoid charge for the first night (Group Policy). Reservations can only be canceled by calling the hotel directly and obtaining a cancellation number.

Travel to Santa Fe, New Mexico

Commercial jets no longer fly into Santa Fe airport, so flights should be booked into the Albuquerque International Sunport (ABQ).

  • Sandia Shuttle Services - The Sandia Shuttle is the main shuttle between ABQ and Santa Fe. We were able to get a discount, so the cost is $40 round trip. To get the discount, make a reservation (AFTER August 15 - they only reserve one month in advance) at 1-888-775-5696, and use the code CIG.

    Sandia operates on a schedule, leaving at certain times, so be sure to check Sandia Shuttle Services to make sure your departure time coincides with their schedule.
