SESE Surface Processes seminar Fall 2017

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. Our off-campus meeting time this term will as usual be 7:00pm-9:00pm on Thursdays.

The Theme this term will be Southwest US Geomorphology. We will read, discuss, critique and debate papers presenting disparate view points on key controversies in surface processes, broadly defined: Geomorphology, Hydrology, Ecology, Biogeochemistry of Surface Environments.

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 Ramon.

Schedule

Date and location	Discussion Leader(s)	Reading/topic
Thursday, August 31; at Kelin's house: 235 E Dawn Drive Tempe	Nari	We've taken this decision to maximally leverage the great colloquium speaker we have next week: Dr. Carmie Garzione, leading world expert on paleoaltimetry. Her applications are mostly in the Andes and Tibet, but it makes sense to kick off our tour through the SW with the fascinating problem of the uplift of the Colorado Plateau, so we are starting with a paleoaltimetry study. Please read by Wednesday and attend Colloquium with Prof. Garzione at 3:30 in Marston Theater. Technical talk following on Thursday 10-11 am, room TBA. Huntington, K., Wernicke, B., and Eiler, J.
