Chemistry of the Arctic Atmosphere (Bill Simpson)

Dr. Bill Simpson talks about studying the Arctic. During springtime, the sea ice in the Arctic is laden with salts, which can be transformed into reactive species in the atmosphere known as reactive halogens. These halogens can react with long-lived species like ozone and mercury. His research aims to understand this process so as to determine the impacts of halogen chemistry on people and ecosystems.
