Victoria, BC has become a favorite stopping point for cruise liners, the majority of which are en route to, or heading back from, Alaska. A record number of 184 ships and 352,000 passengers visited Victoria during the 2006 cruise season (April to October) and 163 calls are expected in 2007. To help understand the impact of the cruise traffic on the surrounding waterways, the intern will use CALPUFF atmospheric dispersion modeling to model emissions from visiting cruise ships and the associated bus and taxi traffic.
