Following seminar by guests has been postponed due to US government shutdown. We are on discussion to arrange alternative date of their visit.

We will invite Justin Rubinstein (US Geological Survey, Menlo Park, CA) and Jack Norbeck (US Geological Survey, Menlo Park, CA/UC Berkeley).
They will give talks at IFS on 10th of January, 10am.
