Term paper
Students will select and read a series of papers on a specific field in seismic
imaging (e.g., data preprocessing, migration in seismic reflection, teleseismic
receiver functions, teleseismic migration, waveform modeling). They will be
required to write a paper (5 pages double spaced) summarizing the field,
including recent advances and current challenges, and give a class presentation
(~20-30 minutes + questions) outlining their findings.
