S32C:
Imaging the Earth II: From Data to Processes on Regional to Global Scales V

Submit an Abstract to this Session Please know the abstract submission deadline has passed. There are no exceptions to this deadline and no new abstracts can be submitted.
You can still search the program to see your colleague�s abstract submissions as well as the sessions submitted for the 2016 Fall Meeting. The final program will be released in early October.


Session ID#: 17875

Session Description:
Through seismic imaging we infer the Earth’s dynamics, composition and evolution. Our view of the Earth is transforming with time thanks to the advent of high-density networks, new modeling techniques, and unprecedented HPC capacity. We invite presentations on seismic imaging from regional to global scales with special focus on quantitative inferences of Earth dynamics as well as discussions on the imaging method resolution that could limit our interpretations. We also welcome presentations on novel techniques that harness large emerging data sets, original measurements, and modern computational methods to develop these intriguing images. Topics like the joint inversion of complementary geophysical data sets, forward and inverse modeling of full waveforms, seismic interferometry, and probabilistic approaches will be gladly received. This session is complementary to session "Imaging the Earth I: Theory and methods at reservoir and local scales". Together, they are intended to promote communication between exploration and global seismology.
