Experimental Course on Supervolcanoes

Spring 2006

This is a unique class, with a diversity of lectures and readings from many sources, meant to make the class cover a wide range of advanced topics, where there is little conventional wisdom from textbooks. The Class meets for discussion each wednesday at 4-530 pm in 211 Dow, beginning Jan 11. The discussions will be held online, with students from other universities. The EHaz universities (Michigan Tech, Buffalo, Mc Gill, Waterloo, UNAM and Colima) will be the main participants, but lectures will come from many other sources. There will be guest lectures every week delivered via powerpoint files with narration or notes. The speaker will join the web discussions on Wednesday pm, to allow for questions and discussion. Each student will receive the powerpoint lectures before the discussion, and review them at their own convenience. The powerpoint will be online for the discussion to allow referring to figure material. The software used for teleconference discussions is Marratech, and Michigan Tech has arranged for a web home connection for our class. Marratech can be accessed from any computer linked to the web and is designed for discussions online.

 

A tentative outline of the class topics follows with a progression from the deep earth to the surface. A rough time schedule is added (we are still filling the lecture schedule!):

Each week the students will read one article, absorb one lecture and participate in one discussion. Students also have an obligation to prepare for the upcoming caldera field trip, this coming May-June. These assignments will come in discussions. The local manager of this class is Karinne Knutsen (klknutse@mtu.edu). She will manage the web page and post the .pdf and .ppt files for downloading by participants. If you have technical issues getting Marratech to work, see this link.
