Abstract
We measured atmospheric dimethyl sulfide (DMS) mixing ratios at approximately hourly intervals over a one-year period (April 2010–March 2011) in the Atlantic sector of the Arctic Ocean (Svalbard, Norway; 78.5¡ÆN, 11.8¡ÆE). The intensive monitoring of DMS levels at Svalbard enabled us to identify in situ production and the flux of oceanic DMS over the Arctic region. It thus constitutes a useful analytical tool for detecting changes in DMS production associated with variations in phytoplankton productivity resulting from changes in sea ice extent as a consequence of Arctic seasonality and warming.
