Lake Guardian
Air Sampler
The Air Sampling equipment is located on the bow of the ship, constructed of aluminum booms with samplers attached at the end. The samplers are set up to point into the wind for several hours, so as to collect air upwind of exhaust stacks. This equipment is used to filter particles and gasses from the air, which are analyzed for atmospheric contaminants. Monitoring these samples enables scientists to determine the quantity of contaminants that enter the lake from the atmosphere.
