Over the past two decades the earth sciences have acquired a wealth of new and high quality data from new and greatly improved observing systems. Because this volume of data poses a major challenge for traditional analysis methods, only a fraction of their potential has yet been exploited. Similarly, results of many advanced numerical simulations of earth processes are only partially analyzed. Hence neither the data nor the modeling are being used to their full potential, leaving crucial questions unresolved. This situation arises in a wide range of areas including earthquake and volcano dynamics, earth structure and geodynamics, climate and weather, and planetary science.

Addressing this situation calls for the application of mathematical methods not currently used, which requires a deeper and long-term dialogue and interaction between the mathematical and geoscience communities. To this end, a workshop was funded by the NSF programs in mathematics and earth sciences to study the feasibility of establishing a semi-virtual institute in Chicago to facilitate a fruitful interaction between a broad and geographically distributed group of mathematicians and geoscientists. Its goal was for earth scientists and mathematicians to identify and explore jointly crucial unsolved problems amenable to mathematical approaches not currently used. This seems feasible if both groups develop a long-term relationship giving each reasonable sophistication with the other's language, problems, and techniques. To set the stage, the meeting illustrated some areas in which collaborative efforts are likely to yield significant advances.
