Group Seminar

In this seminar, we give presentations about our own research. Newcomers to our group talk about their BSc research or previous experience. Sometimes, guest researchers or OB/OG give talks as well.

Held irregularly in the ILTS auditorium, lecture room or conference room.

Reading Circle

For studying basics of glacier physics, we hold this reading circle. Textbook is the most popular one about glacier physics, The Physics of Glaciers (4th. ed.) by Cuffey & Paterson.
Presenter read each part, explain to participants. All participants join discussion, deepen their understandings.

§1. Introduction
§2. Transformation of Snow to Ice
§4. Mass Balance Processes
