Geoscience Subproject

From Minas

Team

• Aaron Velasco (Lead, GS)
• Leticia Velazquez (Math)
• Miguel Argaez (Math)
• Vladik Kreinovich (CS)

Goal

To advance the understanding of the Earth by studying and developing techniques and approaches for integrating data with varying accuracy and sensitivity.

Summary

Subproject 2 teams leading researchers in geophysics and computational mathematics to address a key problem in geophysics: data fusion of distinct information sources in order to determine physical properties of the Earth. This can only be addressed when the 3-D structure of a region of interest can be clearly defined by a velocity, density, anisotropy, and/or attenuation models. Analysis of individual geophysical and geological data sets, however, may lead to different models, mostly due to mischaracterization of errors. The team will apply current and novel techniques from optimization and trust models research (e.g., data assimilation and inversion methods using sensor information) that will advance our understanding of fundamental Earth processes and impact similar projects that collect or analyze large amounts of geophysical data, e.g., EarthScope and environmental sciences.
