Weekly Seminar
We are currently running an informal seminar centered around ice sheets
and glaciers and their interactions with the Earth's surface, oceans,
and atmosphere. Our group meets every Thursday at noon at UTIG in the
2nd floor conference room (2.201) for lunch and discussion of relevant
peer-reviewed papers. If you would like to attend these meetings,
please do!
Email Ginny to be added to our mailing list.
Papers are available online or in Ginny's public folder.
Over the summer, 2007, we will be reading about ice sheet hrounding
lines. The list of papers we will be discussing are as follows:
