SESE Surface Processes seminar Spring 2014

The Earth Surface Processes Seminar (called "Geomorphology Seminar" in the GLG courses list) runs every term, for one unit credit (repeatable any number of times, and we prefer students do enroll) on a different theme each term. The theme for this term's focus is hillslope processes and the critical zone: the interface between the Earth's lithosphere, hydrosphere, biosphere and atmosphere. A broad and highly interdisciplinary topic, we hope this semester will attract faculty and students from a wide range of specialties and spark interesting discussion for all. This is a timely follow-up to a previous surface processes seminar on this same topic (Fall 2010), as new data emerges from the NSF Critical Zone Observatory (CZO) Program.

In a typical session we discuss a single research paper or two short ones. One or a pair of students have the charge to lead the discussion each session. Guiding a discussion, pointing out interesting angles to discuss and keeping the discussion on track are the main tasks. Usually this involves leading the group through the paper, but with an aim to highlighting discussion points rather than a report/summary of all points. Sometimes digging up essential background material from previous papers is essential to either understanding of the paper, or for drawing out key discussion points. Determining whether such ancillary material is needed is up to the student leaders.As we move forward we want to get into full discussion and debate mode -- everyone should make a point of saying at least a couple things in each meeting: a question, answer, comment, observation, whatever. We want all voices engaged in the conversation!

We're looking forward to a vibrant set of discussions this semester! Encouragement from Arjun and Ramón.
