This was 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 met for discussion each Wednesday 
at 4-530 pm in 211 Dow, beginning Jan 11. Discussions were held online, with students 
from other universities. The EHaz universities (Michigan Tech, Buffalo, McGill, UNAM 
and Colima) were the main participants, but lectures will came from many other sources. 
There were guest lectures every week delivered via PowerPoint files with narration or  
notes. Then the speaker joined the web discussions on Wednesday pm, to allow for 
questions and discussion. Each student received the PowerPoint lectures before the 
discussion, and reviewed them at their own convenience. The PowerPoint was online 
for the discussion to allow referring to figure material. The software used for teleconference 
discussions is Marratech, and Michigan Tech 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:

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.
