Description

In order to study the chemical composition of marine aerosol and an impact caused by the primary production in spring season, aerosol sampling and measurement of dimethylsulfide (DMS) concentration were carried out on board of R/V Mirai during MR01-K02 cruise from May 14 to 28 2001.<BR> Based on the relationship between in-situ seawater DMS concentration and chlorophyll-a (CHL-a) estimated from satellite, amount of DMS emitted from the sea surface is estimated along the way of air parcel.<BR> MSA concentration observed on May 25 and 27 was about 2∼3 times higher than the average MSA concentration of this cruise. This enhancement is supposed to be due to a large amount of DMS supplied from high CHL-a area during an air parcel transport.<BR> Besides, nss-Ca2+ concentration between May 18 and 20 was about 3∼4 times higher than the average concentration of this cruise. Trajectory analysis and other approaches such as analysis of physical properties of aerosols in this period showed that Kosa particles were observed in the atmospheric marine boundary layer.<BR> An influence of Kosa particles on the marine production and succeeding sulfur emission should be explored.
