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 seminar is held in the evening, in recent years always on Thursday evening, 7-9 (or 9:30) each week. The seminar is a causal, no-stress, beverage-in-hand, free-ranging discussion of science and the philosophy of science. Location rotates each week among faculty and student houses.
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.
Each week the paper to be discussed, the student leaders, and the location of each seminar will be posted here .
Encouragement from Arjun and Ramón.
The idea for this term's focus is the relationship between climate and erosion and the approaches/techniques available to suss out said relationship. Ideally this week will serve as a springboard to future readings that may range from earlier conceptual papers that dropped the tectonics/climate/erosion gauntlet (e.g., Molnar and England, 1990 and/or Raymo and Ruddiman, 1992), to more recent papers that outline pointed efforts to quantify geomorphic process rates and integrate them into landscape evolution models (likely names include: Roering, Perron, Riebe, Dietrich, Montgomery, Dixon, Granger, Heimsath, Whipple, and other usual suspects). Expect the scope of papers to range from the hillslope scale to the orogen scale to the global scale.
