I just got word back from the ISO about the location of the Earth and Marine Sciences building. It is just East of Nat Sci II, near the science library (new location or old location doesn't matter) for us old townies who don't know about the new campus buildings. A map can be found here:

A map of the entire campus can be found here:

Just click on whatever area you want to have enlarged, and a map simillar to the first one will appear.
