Water samples were collected during a summer bloom of Phaeocystis pouchetii from the beginning, of November 1988, in a 15 m water column 10 km off shore of Davis Station, Vestfold Hill, Antarctica. Results of acrylic acid and DMS determined by HPLC and GC show that concentrations of acrylic acid varied from 0.001 to 0.51 μmol L^<-1> and DMS from 0.003 to 0.588 μmol L^<-1>. Both showed an increase after late December 1988 and maximum concentrations in early January 1989 followed by a rapid decrease to low level by middle January to February. The observed changes of both substances showed good agreement with variations in cell numbers of P. pouchetii, the correlative coefficients of acrylic, acid and DMS against cell numbers of P. pouchetii are all 0:998. The observed highest productivities of acrylic acid and DMS were 9.76×10^<-8> μmol cell^<-1> and 13.09×10^<-8> μmol cell^<-1>, respectively.
