Chemical assessment of oceanic and terrestrial sulfur in the marine boundary layer over the Northern North Pacific during summer

Dimethylsulfide (DMS) in surface seawater and the air, methanesulfonic acid (MSA) and non-sea-salt sulfate (nss-SO^sub 4^^sup 2^-) in aerosol, and radon-222 (Rn-222) were measured in the northern North Pacific, including the Bering Sea, during summer (13 July - 6 September 1997). The mean atmospheri...

Zusammenfassung:	Dimethylsulfide (DMS) in surface seawater and the air, methanesulfonic acid (MSA) and non-sea-salt sulfate (nss-SO^sub 4^^sup 2^-) in aerosol, and radon-222 (Rn-222) were measured in the northern North Pacific, including the Bering Sea, during summer (13 July - 6 September 1997). The mean atmospheric DMS concentrations in the eastern region (21.0 ± 5.8 nmole/m^sup 3^ (mean ± S.D.), n=30) and Bering Sea (19.9 ± 9.8 nmole/m^sup 3^, n=10) were higher than that in the western region (11.1 ± 6.4 nmole/m^sup 3^, n=31) (p
