Course
Description: This
seminar course focuses on introducing and discussing various research topics related
to geophysics. It includes presentations of ongoing research by faculty,
students, and visiting scholars, discussions of recently published papers, and
any current events or activities in relevance to geophysics.
Grading: This one-unit seminar
course is graded as pass or no pass. The grading is mainly based on
participation during class (presentation and discussion). Each enrolled student
is required to give at least one presentation about his or her current or
future research topic. Reading assigned papers thoroughly beforehand is
necessary for discussion in each class.
