Hi,
Welcome to LQ.
You are trying to find the menu entry for it? I think it is in
Applications -> Science -> Geoscience

I've never seen a science menu in Ubuntu, so I could be wrong. OTOH, the newest Ubuntu I have looked at is 6.10, and I ran across a thread from 2006 that indicated some people were trying to get such a menu added, so there could well be one by now.
