EMISSION AND FLUX OF DMS FROM THE AUSTRALIAN ANTARCTIC AND SUB-ANTARCTIC OCEANS DURING THE 1988-89 SUMMER

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-degr ees-E, were determined from a limited number of samples (n = 32) colle cted during three summer resupply voyages to Australian Antarctic cont inental research bases between November 1988 and January 1989 (a 92 da y period). The maximum DMS emission from this sector of the Antarctic Ocean was in an area near the Antarctic Divergence (60-63-degrees-S) a nd the minimum DMS emission was from the Antarctic coastal and offshel f waters. The greatest emission of DMS from this sector of the Souther n Ocean was from the Subantarctic waters. DMS flux from the Australasi an 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.
