This paper deals with the results of composition of CS-C1S hydrocarbons in the regions of the Bransfield Strait. The multivariate statistical analysis is made to recognize the characteristics of the sediments, resulting in that the C5-C15 hydrocarbons contain n-alkanes, iso-alkanes, cyclo-alkanes, aromatic compounds and their substituted compounds as well. The multivariate statistical analysis also shows that stations G-25 and G-27 have the extreme values of factor after rotation.
