Outline of Final Research Achievements

In the Arctic Ocean, surface area of sea-ice has been decreasing in summer season over a few decades due to the global warming, which could lead to positive or negative feedback to the climate system via variations in air-sea exchange of gases related to the climate. In order to clarify the air-sea exchange of volatile organic carbon (VOC), CH4, and CO2, measurements of VOC, CH4, and CO2 were made on board the R/V Mirai (Japan Agency for Marine-Earth Science and Technology) in the Arctic Ocean during the summer period from FY 2014 to FY2016. In Canada Basin we found the water originated from sea-ice melting (less saline water) plays an important role in reducing the air-sea exchange of gases by forming shallow and strong stratification, while active biological activities exist about 30 m below the surface.
