摘要：

DMS emissions and fluxes from the Australasian sector of the Antarctic and Subantarctic Oceans, bound by 46-68-degrees-S and 65.5-142.6-degrees-E, were determined from a limited number of samples (n = 32) collected during three summer resupply voyages to Australian Antarctic continental research bases between November 1988 and January 1989 (a 92 day period). The maximum DMS emission from this sector of the Antarctic Ocean was in an area near the Antarctic Divergence (60-63-degrees-S) and the minimum DMS emission was from the Antarctic coastal and offshelf waters. The greatest emission of DMS from this sector of the Southern Ocean was from the Subantarctic waters. DMS flux from the Australasian Antarctic Ocean was 64.3 x 10(6) (+/- 115) mol d-1 or 5.9 (+/-10.6) x 10(9) mol based on an emission of 10.9 (+/-19.5) mumol m-2 d-1 (n = 26). The flux of DMS from the Australasian sector of the Subantarctic Ocean was probably twice the flux of DMS from the adjacent Antarctic Ocean.
