Global surface temperatures are rising at an unprecedented rate, and the patterns of change during recent decades strongly point to increased man-made emissions of greenhouse gases as the dominant factor. The Arctic is particularly sensitive to this warming. One spectacular effect of this has been a rapid loss of Arctic sea ice in recent years, with major reductions in both its extent and thickness, especially in the summer. Another example is an anticipated increase in the flow of water from the Pacific to the Atlantic through the Canadian Arctic archipelago, which will affect water circulation, ice conditions and the marine microbial food chain. Biological processes in the world¿s oceans, especially those involving phytoplankton (microscopic plants) and bacteria play an important role in the cycles of various gases which influence climate, such as carbon dioxide (CO2), nitrous oxide (N2O), volatile organic compounds (VOCs), halocarbons, and dimethylsulfide (DMS). These gases affect the climate in various ways, either as greenhouse gases, or as sources of aerosols - microscopic dust particles which scatter and absorb sunlight in the atmosphere. It is not known for certain how Arctic climate change will influence the dynamics of these gases in the ocean, ice and atmosphere, but it is reasonable to expect that increased areas of open water, and changes in ocean circulation and temperature will alter the biological and chemical processes which produce and consume climate-active gases and aerosols. It is the goal of the Arctic SOLAS (Surface Ocean - Lower Atmosphere Study) program to explore the interactions between sea ice, water circulation, marine microbiological activity and emissions of these gases from the ocean to the Arctic atmosphere.

Summary: The atmosphere and ocean have a dynamic, lively relationship which is very sensitive to changes in climate and includes complicated chemical and biological processes. Of interest to this project is how changing sea ice and ocean processes affect the chemistry of oceans with the cycling of atmospheric gases and microbiological organisms being of most interest. After two trips on the Canadian research icebreaker CCGS Amundsen, initial findings are unraveling the relationship between the atmosphere and ocean with unexpected changes in such things as biological production and greenhouse gases adding to the complexity of this relationship. Research Program(s): IPY.
