Objective(s): To examine the importance of the ocean as a source of organic bromine to the arctic atmosphere where it may affect ozone concentrations; to further our knowledge of the origins of a range of halogenated carbon compounds in the ocean; to distinguish between natural and anthropogenic sources of halocarbons to the atmosphere.

Project Description: Previous research has indicated that compounds containing bromine could play a role in the destruction of the ozone layer. This study is part of on-going research that is examining how important northern marine waters are as sources of bromine to the Arctic atmosphere. Seawater, snow and ice will be collected and assessed for bromine. In addition, measurements will be taken to determine if seaweeds contribute bromine to the environment.
